Updated: April 16, 2026 | By Sino-Inst Engineering Team

Tank level sensors selection guide by tank content

Most tank level sensor guides start with the sensor — radar, ultrasonic, hydrostatic, capacitance — and tell you what each one does. That is the wrong way around. The fluid you are measuring eliminates more than half the sensor types before you even think about budget. This guide flips the lookup: pick your tank content first, and the right sensor narrows to one or two choices. Use it for new specifications or to second-guess an existing installation that keeps failing.

Step 1: Define what’s in the tank

“Liquid” is not a content category. Conductive vs non-conductive matters for capacitance probes. Dielectric constant matters for radar. Foam matters for ultrasonic. Vapor pressure matters for any non-contact tech. Before specifying anything, write down these six properties of your fluid:

  • Density (kg/m³ at operating temperature)
  • Dielectric constant εr (water = 80, hydrocarbons = 2-4, plastics = 1.5-3)
  • Conductivity (water with salts = high, distilled water = low, oils = none)
  • Viscosity at operating temperature
  • Foam tendency (yes / no / sometimes)
  • Vapor or condensate above the surface (steam, solvent vapor, etc.)

If you cannot get this from the SDS, ask the process engineer who designed the tank. Specifying a level sensor without these numbers is what produces the field calls we get six months later.

Step 2: Continuous reading or point switch?

Continuous transmitters give you a 4-20 mA reading anywhere in the tank’s range. Point switches just close a contact at one fixed level. They cost different orders of magnitude and they fail differently.

NeedUse continuousUse point switch
Inventory trackingYesNo
PID loop / blending controlYesNo
Pump start / stop onlyOptionalYes (cheaper)
Overflow safety / dry-run cutoutNo (use both)Yes (SIL-rated)
Custody transferYes (servo or magnetostrictive)No
Budget under $200Rare (hydrostatic + display)Yes (float, fork)

For pump control, a continuous transmitter feeding the PLC plus an independent float switch as backup is a far more reliable arrangement than two transmitters in voting. The float switch covers the failure mode where the transmitter fails high or stuck. For pump-only switching, see our float switch wiring guide.

Clean water and potable storage

Submersible hydrostatic transmitters are the default. The probe sits at the tank bottom, measures the pressure of the water column above it, and outputs 4-20 mA proportional to depth. Accuracy is ±0.1% FS for quality units, the cable doubles as a vent (atmospheric reference), and there are no moving parts to wear out.

For potable water, choose a NSF/ANSI 61 certified probe. For elevated towers (over 15 m head), check the cable’s vent tube doesn’t sag and form condensate traps — a saturated vent tube reads erratically. The non-contact alternative is 80 GHz radar mounted on the top, which avoids any in-tank hardware but costs roughly 3x.

Fuel, diesel and lubricating oil

Magnetostrictive transmitters dominate this category because hydrocarbons have stable density, low foam, and the float-on-stem principle gives the ±1 mm accuracy that fuel inventory needs. The same probe can carry up to 8 RTDs for ATG (automatic tank gauging) compliance. For an underground or buried tank with restricted top access, the flexible-cable version of the same technology installs through a 2″ riser.

Avoid ultrasonic on diesel — vapor density above the liquid changes the speed of sound, which throws the level reading off by 1-3% as temperature swings. Use it only on water; on fuel it always disappoints in field service.

Acids, caustics and corrosive chemicals

Guided wave radar with a PFA or PTFE-coated probe is the safe specification for sulfuric acid, sodium hydroxide, hydrogen peroxide, and other aggressive chemicals. The radar pulse travels along the probe regardless of dielectric constant, vapor density, or foam. The PFA coating isolates everything but the probe end from the medium.

For storage tanks where in-tank hardware is forbidden by safety policy, fall back to a bubbler system (DP transmitter with a purge gas line). Bubblers are old technology but they are bulletproof on the most aggressive chemicals — nothing wetted is in contact with the tank except the dip tube.

Slurry, sludge and abrasive media

Anything in contact with mining slurry, raw sewage, paper pulp, or cement gets coated, eroded, or both. The default specification is non-contact 80 GHz radar mounted above the tank with a 6° narrow beam and a self-cleaning antenna. Build-up on the antenna is what kills slurry radars; the 80 GHz devices have small antenna footprints and air-purge ports for periodic cleaning.

If radar isn’t an option (sealed tank with no top opening), DP transmitters with remote diaphragm seals on the tank’s high and low pressure taps work — but every cleaning cycle becomes a maintenance event. Avoid floats and capacitance in slurry; both will be disabled within a month.

Food, beverage and pharmaceutical

3A and EHEDG certifications are non-negotiable. Sanitary radar is the dominant choice — flush-mount on a tri-clamp connection, no crevices for product to harbor in, full CIP/SIP cleanability. For low-cost agitated tanks, sanitary capacitance probes work for water-based products but struggle when fat content varies (changing dielectric).

Avoid bubblers (purge gas in product is unacceptable) and avoid contact floats (cleaning impossible).

Cryogenic and extreme temperature

Below -40°C and above 200°C is where most general-purpose level sensors quietly drift out of spec. Magnetostrictive transmitters with cryogenic seal extensions work down to liquid nitrogen temperatures. For LNG bullets, a servo gauge with a stainless float is the API standard.

For molten sulfur, asphalt, and hot oil up to 400°C, guided wave radar with a high-temperature antenna assembly is the only practical continuous solution. Hydrostatic submersibles are not rated; capacitance probes drift severely with temperature. For more on hot-tank installation specifics, see our high-temperature radar level guide.

The common mistake: defaulting to ultrasonic

Ultrasonic level transmitters are cheap, non-contact, and look like a universal solution. They are not. Ultrasonics measure the time-of-flight of a sound pulse to the liquid surface and back. Anything that disrupts the air column between the sensor and the surface throws the reading off.

  • Vapor: any solvent vapor, condensing steam, or even rapid temperature gradients change the speed of sound by several percent.
  • Foam: the pulse reflects off foam, not the actual liquid surface.
  • Dust or fog: attenuates the signal until it reads “lost echo.”
  • Stratified temperature: outdoor tanks in summer have a cool layer near the liquid and hot air at the top — a refraction lens that bends the pulse.

Ultrasonics are appropriate for clean water in open atmospheric tanks at stable temperatures. That is a small slice of real applications. When in doubt, switch to 80 GHz radar — same non-contact installation, immune to all the conditions above, costs about 1.5x.

Featured tank level sensors

Submersible Hydrostatic (Water)

SMT3151TR submersible hydrostatic level transmitter with 316L stainless probe. Drops straight into wells, reservoirs and storage tanks — 4-20mA output for continuous level monitoring.

Magnetostrictive (Fuel)

Magnetostrictive level transmitter with ±1 mm resolution for high-accuracy tank gauging. Preferred choice on fuel depots, API terminals and chemical inventory measurement.

DP Transmitter (Chemical)

DP transmitters measure pressure difference across gas, liquid or steam. 4-20mA / 0-5V output drives liquid level, density and flow loops across process plants.

FAQ

What is the most accurate tank level sensor?

Magnetostrictive transmitters reach ±0.1 mm in custody-transfer configurations, the highest of any commercial tank level technology. Servo gauges (Honeywell Enraf, Endress+Hauser Proservo) match this for tall storage tanks. Hydrostatic and radar are typically ±2-5 mm at best.

What is the cheapest reliable tank level sensor?

For continuous reading on water, a basic submersible hydrostatic transmitter runs $150-300 and works for 5+ years with no maintenance. For point-only level switching, a cable-tilt float switch is under $40. Don’t pay more for fancier tech if your application doesn’t need it.

Can one sensor replace multiple float switches?

Yes. A continuous transmitter feeding a PLC can derive any number of virtual setpoints in software — high-high alarm, high pump-stop, low pump-start, low-low cutoff — from one 4-20 mA reading. The trade-off is single point of failure; most safety systems still keep one independent float switch as a backup.

Do I need radar or ultrasonic for an outdoor tank?

Radar. Ultrasonic readings drift in summer when the air column above the liquid stratifies into hot upper / cool lower zones, and they fail outright in heavy rain or fog. 80 GHz radar is unaffected by atmospheric conditions.

How do I measure level in a tank with foam on top?

Guided wave radar — the radar pulse travels along a probe into the foam and reflects off the actual liquid surface below it. Free-space radar and ultrasonic both reflect off the foam itself and read incorrectly. The other option is a magnetic level gauge with an external chamber: foam stays in the main tank, the chamber sees clean liquid.

What sensor works for solid material in tanks (powders, pellets)?

80 GHz radar with a dust-shielded antenna is the modern default. Guided wave radar with a single rope probe works for tanks under 30 m where the rope can swing freely. Avoid ultrasonic — solids have an irregular angle of repose that scatters the pulse.

How often should tank level sensors be calibrated?

Hydrostatic and DP transmitters drift slowly and benefit from annual zero/span verification. Magnetostrictive and servo gauges measure time-of-flight and don’t drift mechanically — every 2-3 years is usually enough. Radar gauges have no moving parts and need calibration only when something physically changes inside the tank (new internals, repositioned nozzle).

The Secret of Ultrasonic Level Measurement

Posted on by

Updated: April 13, 2026

An ultrasonic level sensor measures liquid or solid levels by sending a sound pulse and timing the echo. No contact with the media. No moving parts. That makes it one of the most reliable options for corrosive, hot, or dirty liquids where other sensors fail fast.

This guide covers how ultrasonic level sensors work, what types are available, where they perform best, and how to avoid the most common sizing and installation mistakes.

Contents

How Does an Ultrasonic Level Sensor Work?

An ultrasonic level sensor emits a short burst of high-frequency sound (typically 20–200 kHz) from a piezoelectric transducer mounted at the top of a tank. The sound pulse travels through air, hits the liquid surface, and bounces back. The sensor measures the round-trip time and calculates distance using a simple formula:

Distance = (Speed of Sound × Time) ÷ 2

The speed of sound in air is roughly 343 m/s at 20°C. Since this speed changes with temperature—about 0.17% per °C—every practical ultrasonic sensor includes a built-in temperature compensation circuit. Without it, a 30°C temperature swing can introduce 1.5% measurement error.

Ultrasonic level sensor measurement diagram: the sensor calculates level from the echo transit time.

The sensor’s microprocessor filters out false echoes from tank internals—pipe fittings, agitator blades, weld seams—using echo suppression algorithms. This is called “false echo mapping” and is configured during commissioning.

What Are the Types of Ultrasonic Level Sensors?

Ultrasonic level sensors fall into two main categories based on output type and measurement method.

By output:

  • Continuous level transmitters — Output a 4–20 mA or digital signal proportional to the level. Used for process monitoring and control.
  • Point level switches — Trigger an alarm or relay at a preset level. Used for overfill protection or low-level alarms.

By mounting:

  • Top-mount (non-contact) — Sensor sits above the liquid. Most common type. Measures through air gap.
  • External clamp-on — Mounts on the outside of the tank wall. Sound travels through the tank material. No process penetration needed. Works on metal and plastic tanks up to 30 mm wall thickness.
TypeRangeAccuracyBest For
Compact transmitter (2-wire)0.3–8 m±3 mmSmall tanks, water treatment
Standard transmitter (4-wire)0.5–15 m±3 mmChemical tanks, open channels
Long-range transmitter1–30 m±5 mmLarge storage tanks, silos
Clamp-on (external)0.1–5 m±5 mmSealed tanks, hazardous media

Ultrasonic vs Radar Level Sensor: Which One Should You Use?

Ultrasonic sensors use sound waves. Radar sensors use electromagnetic waves. That single difference drives all the practical trade-offs.

FactorUltrasonicRadar (non-contact)
Affected by temperatureYes — needs compensationNo
Affected by vapor/foamYes — can lose echoMinimal
Works in vacuumNo — needs air to propagateYes
Max range~30 m~70 m
CostLower ($200–$800)Higher ($500–$3000)
Best applicationWater, wastewater, chemicalsHigh-temp, high-pressure, volatile

Use ultrasonic when the application is straightforward: open tanks, water and wastewater, non-foaming chemicals, and ambient conditions below 80°C. Switch to radar level sensors when you have heavy foam, vapor blankets, high temperature, vacuum, or tanks deeper than 20 m.

What Applications Are Ultrasonic Level Sensors Best For?

Ultrasonic level sensors handle most ambient-condition liquid applications well. Here are the areas where they are the default choice in the field.

Water and Wastewater Treatment

Wastewater plants use ultrasonic sensors in equalization tanks, wet wells, clarifiers, and sludge holding tanks. The non-contact design means no fouling from grease, sludge, or chemical dosing agents. Most municipal plants standardize on ultrasonic for open-top tanks. For more on water tank level sensors, see our selection guide.

Chemical Storage Tanks

Acids, caustic solutions, and solvents corrode contact-type sensors within months. An ultrasonic sensor mounted above the liquid avoids all media contact. Common media include sulfuric acid, sodium hydroxide, hydrochloric acid, and various organic solvents.

Open Channel Flow

Paired with a Parshall flume or V-notch weir, an ultrasonic sensor measures the head (water height) to calculate flow rate. This is a standard setup in irrigation canals, stormwater outfalls, and treatment plant influent channels.

Bulk Solids and Powder

Grain bins, cement silos, and aggregate hoppers use ultrasonic sensors for inventory management. The key: use a sensor rated for twice the actual distance. Dust and irregular surfaces weaken the echo, so the extra power margin ensures a clean return signal. Mount the sensor perpendicular to the material’s angle of repose.

How to Install an Ultrasonic Level Sensor Correctly

Installation errors cause more ultrasonic sensor failures than product defects. Follow these five rules.

  1. Respect the dead zone (blocking distance). Every sensor has a minimum distance (typically 15–50 cm) below the transducer face where it cannot measure. Make sure the maximum liquid level never enters this dead zone.
  2. Mount perpendicular to the liquid surface. Even a 3° tilt sends the echo away from the sensor. Use a level to verify the mounting angle.
  3. Keep away from fill streams. Mount the sensor at least 30 cm from the inlet pipe. Turbulence, splashing, and foam near the fill point cause false echoes.
  4. Avoid obstructions in the beam path. The ultrasonic beam spreads at roughly 5–12° depending on frequency. Ladders, baffles, and heating coils within the beam cone will generate interference. For guidance on stilling well installations, refer to our design guide.
  5. Use a sun shade outdoors. Direct sunlight heats the transducer housing and creates a temperature gradient between the sensor and the air path. This introduces measurement drift. A simple sun shade solves the problem.

How to Select the Right Ultrasonic Level Sensor

Choosing the right ultrasonic level sensor comes down to four parameters.

ParameterWhat to CheckTypical Range
Measurement rangeTank height from sensor to lowest level0.3–30 m
Process temperatureAir temperature at sensor face, not media temp-40 to +80°C
Process connectionThread type and size matching your tank nozzleG1½”, G2″, 2″ NPT, DN50 flange
Output signalMatch your PLC/DCS input card4–20 mA, HART, RS485 Modbus

Also check: Is there heavy foam? (Consider guided wave radar instead.) Is the tank under pressure or vacuum? (Ultrasonic will not work — the sound pulse cannot propagate.) Is the atmosphere dusty or full of vapor? (Select a higher-power sensor or switch technology.)

For explosion-hazard areas, specify an ATEX/IECEx certified ultrasonic sensor. Sino-Inst offers Ex d (flameproof) and Ex ia (intrinsically safe) versions. See our Class 1 Div 1 vs Div 2 guide for zone classification details.

FAQ

Can an ultrasonic sensor measure level through a closed tank?

A standard top-mount ultrasonic sensor works fine in sealed tanks as long as the tank is not pressurized or under vacuum. For sealed tanks where you cannot install a nozzle, use a clamp-on (external mount) ultrasonic sensor that transmits sound through the tank wall.

What is the maximum temperature for an ultrasonic level sensor?

Most standard ultrasonic sensors operate up to 80°C process temperature. The limiting factor is the air temperature at the transducer face, not the liquid temperature at the bottom of the tank. For higher temperatures, consider a radar level sensor.

Does foam affect ultrasonic level measurement?

Yes. Dense foam absorbs the sound pulse and prevents a clean echo return. Light surface foam (less than 5 cm thick) usually does not cause issues. Heavy or thick foam requires switching to a guided wave radar or contact-type sensor.

How accurate is an ultrasonic level sensor?

Typical accuracy is ±3 mm for ranges up to 10 m. Longer-range models (15–30 m) usually spec ±5 mm. These figures apply under stable conditions. Turbulence, temperature gradients, and vapor can degrade accuracy to ±0.5% of range in worst cases.

Can ultrasonic sensors measure solid levels in silos?

Yes. Ultrasonic sensors measure grain, cement, powder, and aggregate levels. The key is to select a sensor with twice the actual required range. The uneven surface of bulk solids scatters the echo, so the extra power compensates for signal loss. Mount the sensor perpendicular to the material’s angle of repose for best results.

What is the difference between an ultrasonic level sensor and an ultrasonic level transmitter?

Functionally, they are the same device. “Sensor” often refers to the transducer element alone. “Transmitter” refers to the complete instrument with signal processing, display, and a calibrated output (4–20 mA or digital). In practice, most people use both terms interchangeably.

Magnetostrictive Level Sensor in Storage Tank Level Measurement

Posted on by

Tank Level Measurement is important for industry storage tank. For example, level measurement of fuel oil tanks and the interface measurement of chemical storage tanks. The liquid level sensor is a kind of level instrument. Hydrostatic, Ultrasonic, Magnetostrictive, Radar, Differential Pressure are commonly choices for tank level measurement. Here, we mainly analyze the magnetostrictive liquid level sensor in the tank applications.

Liquefied petroleum gas is one of the most widely used fuels in civil and industrial production. During the storage and transportation of liquefied petroleum gas, liquid level measurement is an important task of the project. It is required not only to have high accuracy for liquid level measurement. It must also be able to adapt well to the working conditions of closed pressure vessels. At the same time, in order to meet the needs of remote monitoring and management. It must also require the measurement data to have the function of long-distance transmission.

Analysis and comparison with other level sensors

(1) Optical fiber level gauge
Based on optical technology. Use optical fiber as the sensor unit. Take out the sensitive state as an optical signal. Then photoelectric conversion. So it is easy to match with highly developed electronic control devices.

Compared with other conventional sensors, optical fiber sensors have high sensitivity, fast response speed, and strong resistance to electromagnetic interference. Corrosion resistance, good electrical insulation, small size and easy to form a remote monitoring network with optical fiber transmission system. Especially in the harsh environment of flammable and explosive, it is widely used.

(2) Differential pressure level gauge.Differential pressure level gauges use the principle of liquid pressure. At the bottom of the liquid, check the pressure difference between the liquid pressure and the standard atmospheric pressure. It deforms the semiconductor diffusion silicon film through the pressure of the liquid bottom.

Cause the bridge to be unbalanced. The circuit outputs a voltage corresponding to the liquid level height. In order to obtain the liquid level signal. It has the characteristics of high precision (0.7%), small drift and strong anti-overload capability.

But when the density of the medium changes with the temperature, pressure and composition of the medium, the differential pressure level gauge will produce a false level.

Extended reading: Hydrostatic Level Measurement

(3) Servo level gauge.
The servo liquid level gauge controls the float to follow the liquid level or interface changes through the servo motor. The servo float level gauge is subjected to different buoyancy forces on the liquid surface, in the liquid and on the interface through the float.

The gravity sensor is used to measure the weight of the float. It can send out long-distance signals at the same time. Use microcomputer for remote control. Its dynamic tracking error can reach 0.1mm.

At the same time, it can also compensate for the additional weight error caused by the low liquid level. The measurement accuracy of the liquid level can reach 0.7mm. The sensitivity can reach 0.1mm.

In addition, it also has self-diagnosis and communication functions. The level gauge has high reliability. But the price is relatively high.

(4) Radar level gaugeThe use of radar waves to measure the liquid level is a technology that has been paid close attention at home and abroad in recent years. It uses a horn-shaped waveguide to emit low-power microwaves (tens of microwatts).

Extended reading: Radar Oil Tank Level Sensor

After encountering the tested interface, part of the microwave is reflected back. Received by the transmitter and receiver combination level gauge system. Indirectly measure the liquid level by measuring the time difference between transmission and reception.

The biggest feature of the radar level gauge is that it is suitable for the environment where the application effect of the ultrasonic level gauge is not ideal.

Its maximum range can reach 35m, and the measurement accuracy can reach millimeter level. But its disadvantage is that the price is too high. Can not withstand high temperature and high pressure.

Advantages of stainless steel magnetostrictive level sensor for oil Tank Level Measurement:

  1. High precision: the magnetostrictive liquid level gauge uses waveguide pulse to work. During the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse. Therefore, its measurement accuracy is high. The resolution is better than 0.01% FS. This is an accuracy that is difficult to achieve with other sensors.
  2. Good safety: the magnetostrictive liquid level gauge has high explosion-proof performance. Safer to use. Especially suitable for the measurement of chemical raw materials and flammable liquids. It is not necessary to open the tank lid during measurement. There is no insecurity for manual measurement.
  3. Strong reliability: Because the magnetostrictive liquid level gauge uses the waveguide principle. There are no mechanically movable parts. So there is no friction and no wear. The entire converter is enclosed in a stainless steel tube and does not contact the measuring medium. The sensor works more reliably and has a longer life.
  4. Facilitate system automation: The secondary instrument of the magnetostrictive liquid level gauge adopts standard output signal. Help the computer to process the signal. It is easy to work on the Internet. Improve the automation of the entire measurement system.
  5. Simple installation and maintenance: the magnetostrictive liquid level gauge is usually installed through the existing nozzle on the tank top. It is especially suitable for the installation of underground storage tanks and already put into operation. And will not affect normal production during the installation process.

What is tank level measurement

Tank level measurement is a general term for measuring the static storage of liquid products in large storage tanks. It can be used for inventory measurement, which is to determine the total amount of products in the storage tank.

It can also be used for transmission and transfer measurement, that is, as a basis for product purchase, sale and tax payment. There are two main methods: volume-based and mass-based measurement.

Tank level measurement using pressure

Pressure level sensors can be used to establish levels in rivers, tanks, wells or other liquids. The pressure at the bottom of the liquid-filled container is directly related to the height of the liquid.

The transmitter measures this hydrostatic head and provides a final level. In order to obtain an accurate reading, the measuring device must be located at the lower point where you want to measure; it is usually installed or placed at the bottom of the container.

When measuring the liquid level, the specific gravity must be considered. Consider the following equation:

     H = P / SG or P = SG? H

H-the height of the measured liquid. It is usually measured in inches, centimeters, meters, feet, etc.
P-Hydrostatic head at the bottom of the tank. Usually in inches of water column, feet of water column, horizontal bar, psi, Pascal’s, etc.
SG-the proportion of the medium. The dimensionless number is calculated from: measured medium density ÷ water density at 4 ° C. For example, the density of kerosene is equal to 0.82 g / cm 3. Therefore, the kerosene of SG is 0.82g / cm 3 · 1.00g / cm 3 = 0.82.

Radar tank level measurement

Radar level transmitter, also called Radar level gauge. Non-contact Continuous level measurement in liquids and solids with free space radar sensors. Non-contacting radar, based on microwave technology, detects only surfaces that reflect energy.

These transmitters work on the principle of a radar by using radio wave emissions. Mounted at the top of a tank filled with a liquid. The transmitter sends a radar signal into the liquid, and receives a reflection of the signal. The transmitters then analyze the current fill level of the tank based on the time taken by the transmitted signal to return.

Hydraulic oil is the hydraulic medium.

Hydraulic oil is used in hydraulic systems that utilize fluid pressure energy.

Its role is Energy transfer, anti-wear, system lubrication, Anti-corrosion, anti-rust, cooling, etc.

1. Hydraulic systems for automobiles and construction machinery use hydraulic oil as the working medium. In this type of hydraulic system, the fluid velocity is not large and the pressure is high, so it is called static pressure transmission.

2. Hydraulic oil is widely used, and it is the most used product in industrial oil. Hydraulic components are developing in the direction of small size and high power. The system pressure is getting higher and higher, and some have exceeded 50 MPa.

More:

  1. Hydraulic pressure is a term for the machinery industry and electromechanical industry. Hydraulic power can be powered by hydraulic power. Hydraulic pressure can also be used as a control method, which is called hydraulic pressure control.

The hydraulic flow meter is a flowmeter that can measure hydraulic oil. The hydraulic flow meter is a name called according to the measurement medium in the industry.

There is no hydraulic oil flow meter in the strict sense. It is not accurate to say which flowmeter is a hydraulic flow meter. Which one to use depends on the specific flow measurement conditions.

For example, the hydraulic oil is also labeled, 40 #, 46 #, or other viscosity properties. Then choose a suitable flow meter according to the relevant information such as flow, pressure, viscosity, and so on.

Here are some common types of hydraulic oil flow meters and what they do:

  • Gear Flow Meters: These meters have gears that rotate to measure oil flow. They work well with thick fluids.
  • Turbine Flow Meters: These meters use a spinning part to measure flow. They work with different flow rates and clean fluids.
  • Variable Area Flow Meters: Also called rotameters, these meters use a tube and a moving float to measure flow. They’re simple and work with many fluid types.
  • Positive Displacement Flow Meters: These meters measure fluid flow by trapping and counting fluid. They’re accurate and good for thick fluids like hydraulic oil.
  • Mass Flow Meters: These meters measure the mass of fluid flowing through a system instead of volume. They are useful in situations where fluid density changes can impact the accuracy of volumetric flow meters.
  • Ultrasonic Flow Meters: These meters use sound waves to measure flow without touching the fluid. They’re good when you want to avoid fluid contamination or pressure loss.

Knowing the different types of hydraulic oil flow meters helps you pick the best one for your needs.

High-Pressure Turbine Flow Meter series of turbine flow meters is ideal when measuring the flow of fluids under high pressure, such as in hydraulic testing.

How to use a hydraulic flow meter?

  • A flow meter can be placed in any location of the hydraulic line to detect the flow rate. Flow meters with variable port sizes are available that are suitable for different hydraulic systems.
  • When the hydraulic system operates, the fluid is passed towards the flow meter.
  • A flow meter mainly contains 3 parts; the primary device, a transducer and a transmitter. The transducer senses the hydraulic fluid passing through the primary device.
  • And a usable flow signal is generated by the transmitter when the sensed signal is sent by the transducer.
  • The volume is calculated based on the principle that the volume of fluid passing is directly proportional to the cross-sectional area and the fluid velocity.
  • Also, the mass flow is directly proportional to fluid density and volume.
  • Then, this calculated hydraulic measurement is displayed on the hydraulic flow meter gauge.
  • All standard hydraulic oil flow meters supports unidirectional flow.
  • But, reverse flow by-pass options are also available with some selected flow meters.
  • Selecting a hydraulic flow meter is a difficult procedure. A wrong selection will cause errors in the diagnosed result.
  • The factors that need to be considered while selecting a hydraulic flow meter are:
    • the hydraulic fluid properties.
    • operating condition of the hydraulic system.
    • the need for measuring flow.
    • the level of accuracy required.
    • the effect of fluid on flow meter and vice-versa.
    • and finally the budget.

What is an inline flow meter?

The online flow meter is actually a flow meter displayed on the spot. At present, all integrated flow meters are online flow meters. All have local display function.

For example, the split-type flowmeter has no local display function. Its meter head and sensor are connected through conduction, and the online flowmeter is the mainstream measuring instrument in current flow measurement.

What are the advantages of online flow meters in the flow measurement process? In some measurements with a control system, the advantage of the online flowmeter is not great. Because the size of the flow can be monitored through the PLC system. And there is no PLC system in the working condition. The online flowmeter can show its advantages, and it can display the accumulated flow and instantaneous flow online.

The D represents the diameter of the pipe. For the orifice plate in the orifice plate flowmeter, the minimum requirements for the front and rear straight pipe sections are 10D Upstream and 5D Downstream. If there is a pump or regulating valve in front of the orifice plate, then the requirements for the straight pipe section are greater.

There are many types of flow meters.

According to the different structural principles of the flowmeter, it is divided into:

  1. Differential pressure flowmeter: orifice plate, bar type such as Annubar, V cone, wedge type, elbow, nozzle, target type, etc.

Extended reading: Metal Tube Flow Meter-Variable Area Flow Meters Principle

Flow is the amount of fluid that passes through a pipe or device at a cross-section in a unit of time. This quantity is expressed by mass and is called mass flow. Expressed by volume, called volume flow. Expressed by weight, called weight flow.

Because the density of a fluid changes with changes in the state parameters of the fluid, the volume state must be given while specifying the state of the fluid.

Especially for gas, its density varies significantly with pressure and temperature. In order to facilitate the comparison of the volume flow rate, the volume flow rate in the working state is often converted to the volume flow rate in the standard state (temperature is 20 ° C and absolute pressure is 101325Pa).

Commonly used flow measurement methods include speed-type flow measurement methods, volumetric flow measurement methods, and direct or indirect methods to measure the mass of fluid flowing through the cross section of the pipe per unit time.

In the above method, more speed-type flow measurement method instruments are applied.

Except for the standard throttling device which does not need to be tested for the current flowmeter, almost all other flowmeters need to be calibrated when leaving the factory. During the use of the flowmeter, it should also be calibrated frequently.

The volume method is most commonly used. This is a method of measuring the volume of fluid flowing into a constant volume container within a measurement time to obtain the flow rate.

The mass method is a method of weighing the mass of a fluid flowing into a container within a measurement time to obtain a flow rate.

During calibration, a pump is used to draw the test fluid from the liquid storage container through the calibrated flowmeter and enter the liquid container.

The temperature of the fluid is measured while the weight is weighed to determine the density of the measured fluid at that temperature.

Divide the weight of the measured fluid by the density of the fluid at the measured temperature to obtain the volume of the fluid.

Comparing it with the meter’s volume indication (accumulated pulse number), the meter constant and accuracy of the calibrated flowmeter can be determined. The accuracy of this system can reach 0.1%.

The working principle of the standard volume tube method is based on the volumetric method (standard volumetric method), but it is a dynamic measurement.

The standard flowmeter comparison method is to connect the calibrated flowmeter and the standard flowmeter in series to the pipeline flowing through the test fluid, and compare the two measured values ​​to find the error. The accuracy of the standard flowmeter is 2 to 3 times higher than that of the calibrated flowmeter.

Where are flow meters used? Or, What does a flow meter measure?

At industrial sites, meters that measure fluid flow are referred to as flow meters or flow sensors.

It is one of the most important instruments in industrial measurement.

With the development of industry, the accuracy and range of flow measurement requirements are getting higher and higher.

In order to adapt to various purposes, various types of flowmeters have been successively launched,

widely used in oil and gas, petrochemical, water treatment, food and beverage.

Industries such as pharmaceuticals, energy, metallurgy, pulp and paper, and building materials.

  1. Measurement of gas mass flow in industrial pipelines
  2. Smoke flow rate measurement from the chimney
  3. Calciner flue gas flow measurement
  4. Air flow measurement during gas process
  5. Compressed air flow measurement
  6. Gas flow measurement during semiconductor chip manufacturing process
  7. Gas flow measurement in sewage treatment
  8. Gas flow measurement in heating ventilation and air conditioning systems
  9. Flux recovery system gas flow measurement
  10. Measurement of combustion gas flow in a combustion boiler
  11. Gas flow measurement of natural gas, flare gas, hydrogen, etc.
  12. Measurement of carbon dioxide gas flow during beer production
  13. Measurement of gas mass flow in the production process of cement, cigarette and glass factory
  14. Open channel

Flowmeters are devices that measure the rate of liquid, gas or vapor that passes through them.

Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute).

Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).

Flow measurement can be described by :
Q = A x v

Q is flow rate, A is the crosssectional area of the pipe, and v is the average fluid velocity in the pipe.

Putting this equation into action, the flow of a fluid traveling at an average velocity of a 1 meter per second,

through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second.

Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate.

Now consider the following equation:
W = rho x Q

Where W is flow rate (again – read on), and rho is the fluid density.

Putting this equation into action, the flow rate will be 1 kilogram per second,

when 1 cubic meter per second of a fluid with a density of 1 kilogram per cubic meter is flowing.

(The same can be done for the commonly-used “pounds”. Without getting into details — a pound is assumed to be a mass unit.)

Note that W is a mass per unit time, so W is commonly denoted as the “mass” flow rate.

Now — which flow do you want to measure? Not sure? In some applications, measuring the volumetric flow is the thing to do.

Consider filling a tank.

Volumetric flow may be of interest to avoid overflowing a tank,

where liquids of differing densities can be added.

(Then again, a level transmitter and high level switch/shutoff may obviate the need for a flowmeter.)

Consider controlling fluid flow into a process that can only accept a limited volume per unit time.

Volumetric flow measurement would seem applicable.

In other processes, mass flow is important.

Consider chemical reactions,where it is desirable to react substances A, B and C.

Of interest is the number of molecules present (its mass), not its volume.

Similarly, when buying and selling products (custody transfer) the mass is important, not its volume.

In recent years, flow measurement technology has developed rapidly. Most of the steam flow measurement uses differential pressure flowmeters and vortex flowmeters.

In practical applications, the maximum diameter of the high temperature vortex flowmeter can only be 300mm and the maximum temperature is 450℃. Therefore, in the measurement of high temperature and high pressure large-diameter steam flow, the differential pressure flowmeter still has unique advantages. For example, Annubar flowmeter, differential pressure orifice flowmeter, etc.

Differential pressure flowmeter manufacturing technology and national and international standards are quite mature. With the introduction of the multivariable transmitter dynamic full compensation intelligent technology, the accuracy of high temperature pressure and large diameter steam flow measurement has been greatly improved, and the installation and maintenance workload has been reduced.

Fuel flowmeter refers to the flowmeter used to measure the flow rate of fuel. Commonly referred to as turbine flow meters and oval gear flow meters.

A flow meter is used to measure the quantity of fluid that has been moved during the transfer process. They have a visual display, which can be either mechanical or digital, for the user to read off the measurement. Flow meters are used within a variety of fluid transfer applications. And therefore whilst they are always used to measure the fluid, the ways in which they work are slightly different.
Of course, the fuel flow meter also has some characteristics of its own, such as:
Explosion proof
Pulse output
Unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

If you need more accurate measurement, you can choose a mass flow meter. Coriolis mass flowmeters have zero drift but the impact is relatively small. Higher operating costs. Mass flow meters can measure temperature and density online. Oval gears are relatively stable for mechanical flow meters.

Turbine Flow Meters are the most widely used diesel fuel flow meters. Measure your diesel fuel or oil consumption with our fuel flow meter.

Diesel Flow Meter Working Principle

The working principle of the turbine flow meter:

Fluid flows through the sensor housing.Because the blade of the impeller has a certain angle with the flow direction, the impulse of the fluid causes the blade to have a rotating moment.

Blades rotate after overcoming frictional torque and fluid resistance.After the torque is balanced, the speed is stable.Under certain conditions, the speed is directly proportional to the flow rate.

Because the blade is magnetically permeable, it is in the magnetic field of a signal detector (made of permanent magnetic steel and coils).

The rotating blade cuts the magnetic field lines and periodically changes the magnetic flux of the coil.

Thereby, an electric pulse signal is induced at both ends of the coil.This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude.

Remotely transmitted to the display instrument, show the instantaneous flow rate and cumulative amount of the fluid.In a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.

In addition to supplying diesel flowmeters, Sino-Inst also supplies various diesel level sensors.

A flow meter is an instrument that indicates the flow rate to be measured and/or the total amount of fluid in a selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.

Flowmeters are devices that measure the rate of liquid, gas or vapor that passes through them.

Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute).

Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).

Flow measurement can be described by :
Q = A x v

Q is flow rate, A is the crosssectional area of the pipe, and v is the average fluid velocity in the pipe.

Putting this equation into action, the flow of a fluid traveling at an average velocity of a 1 meter per second, through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second.

Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate.

Now consider the following equation:
W = rho x Q

Where W is flow rate (again – read on), and rho is the fluid density.

Flow Meters Pulse Output

The signal output by the flowmeter is generally a pulse signal or a 4-20mA current signal. Both types of signals output instantaneous flow (also used by relays to output cumulative signals. The principle is the same, and will not be repeated).

Our purpose is to PLC Calculate and display the instantaneous flow value and calculate the cumulative value. When the input signal is a pulse signal. When calculating the instantaneous flow rate, you must follow a strict time interval to ensure the accuracy of the instantaneous flow rate.

So, when calculating the instantaneous flow rate, This must be done using timed interrupts. Moreover, only one interrupt program can be run in a PLC system. No other interrupts are allowed (even low priority interrupts are not allowed to run).

Prevents interference with the accuracy of timed intervals. Calculating the instantaneous flow rate is to convert the accumulated pulse number of this time period into the accumulated flow rate. Divided by time is the instantaneous flow.

For the 4-20mA input, the instantaneous flow rate can be directly obtained by simply converting according to its corresponding range. The cumulative flow is the cumulative flow accumulated in each time period is the cumulative flow.

Flow meters with a pulse output essentially use pulses per litre to measure the amount of fluid being dispensed. And then send a signal to an external piece of equipment to tell them this information.

A fuel pulse meter for example is often connected to a remote display or a fuel management system.

Our range of fuel pulse meters include models suitable for different fluids and are compatible with pumps with differing flow rates. Ensure that when selecting your meter, its flow range meets your pump’s flow capabilities.

Of course, in addition to measuring Diesel Fuel flow meters. Other flow meters can also output pulses or 4-20mA signals.

For example, if you need to measure the waste water flow of a 2-inch pipe, then you can refer to: Magnetic Flow Meters Guides.

Fuel Flow Meters for Diesel Engine Fuel Consumption

For generators, boats, trains to hydraulic packs applications. Diesel engines are becoming increasingly popular.

Fuel consumption and efficiency are generally not monitored in Diesel Engines. And the unit’s performance has to be gauged from the manufacturer’s test figures and often never checked again.

With increases in fuel prices, the possibility of theft from remote installations along with many other factors. So the monitoring the fuel consumption of diesel engines has become increasingly important with the transport industries in particular taking a lot more interest in their vehicles fuel consumption.

This chart approximates the fuel consumption of a diesel generator. Based on the size of the generator and the load at which the generator is operating at. Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation. And is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed.

Fuel flow meter aircraft

A fuel flowmeter for plane indicates an engine’s fuel use in real time. This can be useful to the pilot for ascertaining engine performance and for flight planning calculations.

The types of fuel flow meter used on an aircraft depends primarily on the powerplant being used and the associated fuel system. Not every plane or associated system uses the same kind of flow meter to get the job done.

In most cases, many flow meters perform tasks related to maintaining a single plane. Some of the more common flow meters in use include:

  • A mass flow fuel flow indicating system used on turbine-engine aircraft uses the direct relationship between viscosity and mass to display fuel flow in pounds per hour
  • A turbine flow transducer in this fuel flow sensor produces a current pulse signal from an opto-electronic pickup with a preamplifier
  • A transducer and microprocessor for control functions are located in the base of this turbine fuel flow sensor. The gauge is menu driven with numerous display options

https://www.aircraftsystemstech.com/2017/06/fuel-system-indicators.html

Every flow meter must be properly maintained and calibrated. All flow meters become inaccurate over time through regular use. Regular re-calibrations and general standards to ensure proper operation.

Flow meters designed for the aviation industry are made of the highest quality materials and to specific industry standards. That way, everyone working in the industry and flying the skies can be in the safest environment possible at all times.

  • How much fuel is consumed onboard a ship, is directly related to the performance. The better the performance, the lower the fuel consumption during operation. In this equation, accuracy is not negligible.
  • An offset of 1% in measurement on a vessel operating 200 days a year consuming an average of 100 tons a day equals an offset of 200 tons a year. Depending on the price of HFO or MGO used, this misread has the potential to range up to USD 100,000.
  • The Coriolis Mass Flow Meters used in our Fuel Consumption System has an accuracy better than 0,2% of nominal flow directly measured in mass. Whereas most volumetric flow meters are in the range 0,5% to 2,0%. And they rely on volumetric conversion which depends on the temperature to calculate a mass flow.
  • By installing one or more mass flow meters (depending on engine supply line layout and desired insight) fuel consumption can be monitored closely in real-time.
  • The main principle is to measure the flow of fuel before and after the engine and/or generators. When you compare the consumption data with measurements of actual speed and position (based on speed log and GPS signals). You are able to directly measure the fuel efficiency.
  • If you require more detailed readings, for example, one set of meters per consumer or one set for the ship’s entire consumption. Additional flow meters can be installed.

Air flow meters types

The Carmen vortex refers to the placement of a cylindrical or triangular object in the fluid. Two rows of vortices with opposite rotation directions will be generated downstream of this object.

More about Types Of Air Flow Measurement Instruments.

An ultrasonic transmitting probe and a receiving probe are oppositely installed on both sides of the downstream pipeline of the Carmen vortex generator. Due to the influence of the Carmen vortex on the air density, the time from the transmitting probe to the receiving probe of the ultrasonic wave becomes later than that of the non-vortex and a phase difference occurs. By processing this phase signal, a vortex pulse signal can be obtained.

The working principle of the hot film type air flow meter is similar to that of the hot wire type air flow meter, and they all work with Wheatstone bridge. The difference is that the hot film type does not use platinum wire as a hot wire. But uses a thick film process to make the hot wire resistance, compensation resistance, and bridge resistance on the same ceramic substrate.

In the process of generating the Carmen vortex, the air pressure on both sides of the vortex generator will change. The pressure acts on the metal foil through the pilot hole, causing it to vibrate. When light from a light-emitting diode strikes a vibrating metal foil. The reflected light on the metal foil received by the phototransistor is vortex-modulated light. And its output is demodulated to obtain a frequency signal representing the air flow.

When no air flows, the bridge is in equilibrium. The control circuit outputs a certain heating current to the hot wire resistance RH. When there is air flowing, the heat of RH is absorbed by the air and becomes cold. Its resistance value changes. The bridge loses Balance. If the temperature difference between the hot wire resistance and the intake air is kept constant and constant, the current IH flowing through the hot wire resistance must be increased. Therefore, the hot-wire current IH is a function of the mass air flow.

The vane type air flow meter has a simple structure and high reliability. Yet, it has a large volume, large intake resistance and slow response.

Working Principle of Slurry Flow Meters

Different types and designs of flow meter are available. Choose the best one depends on the application and the type of liquid being measured. Electro-magnetic meters are typically used for slurry and corrosive liquids. Because magnetic flow meters are able to measure these substances accurately.

Keeping accurate records is essential. Because we need to know exactly how much slurry has been spread in every field, and to demonstrate full regulatory compliance.  Today’s modern slurry flow meter designs can help to achieve this.

What is the principle of magnetic flow meter? – Faraday’s Formula

Faraday’s Formula
E is proportional to V x B x D where:

E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor

To apply this principle to flow measurement with a magnetic flow meter. First is to state that the fluid being measured must be electrically conductive for the Faraday principle to apply.As applied to the design of magnetic flow meters, Faraday’s Law indicates that:the signal voltage (E) is dependent on V, B, D.V is the average liquid velocity ;B is the magnetic field strength ;D is the length of the conductor ( which in this instance is the distance between the electrodes).

Why do you need a slurry flow meter?

When spreading any type of slurry or digestate, accuracy is essential. This means it is important to monitor the spreading process with a slurry flow meter. So that you can be sure of consistent application across the area which is being treated.

At the same time as ensuring that enough slurry is applied, however, it is equally vital not to use more than is needed. This is important for several reasons. One is that over-application is a waste of valuable slurry resources, meaning you spend more than is necessary. Slurry is one of the most cost-effective ways of fertilising agricultural land. But only the application carried out properly..

Spreading too much slurry can also lead to a number of pollution issues. Which could risk failing to comply with legal regulations. Especially if it involves contamination of soil or water courses.

Challenges for Slurry Flow Meter

Flow meters designed for slurries depend on several factors:

  • The flow velocity and profile. A balance of keeping solids moving, but not too fast.
  • The amount of solids in the carrier fluid.
  • The solids properties in the carrier fluid.  They vary in many qualities including shape and size.
  • Chemical composition of the fluid. Liners for corrosive fluids.
  • Solid Abrasiveness. Rough solids cause system noise that interferes with the measurement. Abrasiveness liners can be used if needed.
  • Heavy slurry noise may affect on the measurement accuracy and stability
  • Shorter replacement cycle because of the mechanical damage caused by slurry.
  • High density red-mud covered on the electrodes requires frequent maintenance for the cleaning.

Sino-Instrument’s solutions for Slurry and Solids flow

Looking for a meter to monitor slurry spreading? Sino-Instrument offers high-quality magnetic flow meters which complies with many official standards. It is known for being highly reliable and durable, needing little maintenance to keep it in good working order. The magnetic flow meter is used in the waste water industry and other sectors as well as for slurry, which is a testament to its quality.
To monitor slurry application, the magnetic flow meter can be easily installed within the pipeline, positioned either near to the pump or on the applicator. It has strong liners which are resistant to slurry, and will measure the flow rate accurately, usually in m3 per hour.
Non-retained liners (extruded liner) are susceptible to failures as a result of vacuum conditions that can be created due to a pump or valve failure. Besides, meters that have extruded liners generally have a shorter life due to the aggressiveness of the chemicals used. Sino-Instrument uses an injected molded PFA liner with a retaining grid. This retaining grid plate, used to reinforce the PFA liner, acts like rebar in concrete. This rugged construction holds the liner in place and prevents the liner from caving in due to vacuum conditions. The thickness and durability of the injection molded PFA liner provides a flow tube that is capable of handling the most severe applications.

Industrial Vortex Flow Meter

Compressed air flow meter working principle

There are a variety of measurement principles can be used to measure compresses gas.

Turbine gas meters are robust meters, used to measure gas consumption. In gas distribution, transmission, industrial plants and for commercial users. The meter tracks the flow rate continuously, offers little resistance to flow, and has a unique cartridge design that allows removal of all internal parts as one assembly.The meter also exhibits little sensitivity to gas density above two atmospheres pressure.The low inertia of the rotor and vee bearings, allows overhanging of the meter to twice its rated capacity, without damage for intermittent flow variations.  Orifice plates and venturi tubes rely on detecting the differential pressure across a restriction in the pipe,and this pressure is directly proportional to the media velocity. Given knowledge of the pipe dimensions and media characteristics,a differential pressure instrument can give a reading directly in flow units. The accuracy of these systems are reliant on very fine tolerance machining of the orifice or venturi and the pressure drop incurred,through the installation of these devices may not suit all situations. These can be highly accurate and reliable but are expensive and complicated to install and maintain. Pitot tube systems work on a very similar principle and remove the issue of the pipe restriction,as there is only a small diameter tube inserted at right angles to the flow. These can be inserted through ball valves, making removal for service or calibration very simple. This method does not need perfectly dry and pure gases to be accurate,and is very tolerant of wet gases and contaminants which makes it ideal for measuring in difficult places. Such as compressor outlets. Vortex meters place a bluff restriction in the pipe,that causes vortices to form alternately on the 2 rear edges. Sensors are used to detect the formation of these vortices, the frequency of which is directly proportional to the flow rate. These instruments are accurate but again introduce a large restriction into the pipe,and are often employed on steam applications.

What about Thermal Mass?

Thermal mass meters and calorimetric flow sensors sense the cooling effect on a heated element,which is directly proportional to the mass flow rate rather than the volumetric flow rate. This removes the subsequent calculations needed to determine mass flow rate,using other methods of flow measurement, and there is no pressure or temperature compensation necessary.The actual sensing tips are small and thus the restriction placed,in the pipe produces very little back pressure, making this method ideal for very low and very high flow rates.Thermal mass meters are available in a range of accuracies and are ideal for dry, clean gas flow measurement. Some designs have all stainless steel wetted parts making them better suited to contaminated or corrosive gases,which would damage the exposed sensing elements of unprotected designs. They are not suitable for wet gases or steam. For those applications a pitot tube design or possibly a vortex meter would be the better choice. Thermal mass is also an excellent principle for use in flow switches,as there are no moving parts in the media and the sensor produces very little back pressure due to its minimal size. These flow switches are very sensitive and some models can be used to determine flow direction as well as flow/no flow.

If you let me answer this question. I would like to divide flow meters into two categories: mass flow meters and volumetric flow meters.

Of course, it can also be divided according to the measurement medium. There are two types of flow meters for measuring gas and measuring liquid.

Perhaps, we can also divide into closed pipeline measurement and open channel measurement according to the situation of the pipeline.

Finally, we may also be able to divide into contact and non-contact measurements according to the contact situation of the medium.

There are differences in the allowable error of the measurement accuracy of the commonly used flowmeters, as follows.

  • Mass flow meter 0.05%;
  • Positive displacement flowmeter 0.25～0.5;
  • Electromagnetic flowmeter 0.25～1.0;
  • Turbine flowmeter 0.15～0.5;
  • Vortex flowmeter 0.15;
  • Ultrasonic flowmeter 0.10 (multi-channel is better than 0.5);
  • Orifice plate, micro cone, uniform velocity tube flowmeter 1 to 1.5, nozzle 0.10.

Relatively speaking, mass flow meters have the highest accuracy.

Both the accuracy and error of a flowmeter characterize the ability of a measuring instrument to approximate the actual true value of the measurement results. The higher the accuracy of the instrument, the closer the measured value is to the actual true value. The higher the accuracy, the smaller the error.

Many people feel that the flow meter (flow meter) is the same as the water meter to measure water, but it has the essence but different. However, a water meter is a type of flow meter (flow meter). Let’s talk about the difference between the two of them.

The flow meter (flow meter) can measure the instantaneous flow, and can understand the usage of each site. The water meter mainly has the accumulation function, and the instantaneous flow Q cannot be seen.

A water meter is also a type of flowmeter. It is a volumetric measurement with an accumulation function. The household water meter is a small flow measurement flow meter. It is not resistant to high pressure and high temperature, and cannot output linear signals. Unable to participate in the automation control of modern industry. Basically only metering water, certainly not for metering gas. Some liquid media also cannot be applied.

To put it simply, water meters are generally only used to measure water and have a wide range. Flow meters can measure liquids, gases, vapors, or two-phase.

The installation positions of different flowmeters have different requirements for straight pipe sections.

Liquid flow meters are generally better installed at low places. Because this can make the part of the liquid passing through the flow meter reach the state of full pipe.

Gas flow meters are generally installed high in the pipeline.

And almost all flow meters require a certain length of straight pipe. Different flow meters require different straight pipe lengths.

If there is anything you want to know, please contact us.

The general measurement is to use an electromagnetic flowmeter.

Magnetic flowmeters use the principle of Faraday’s Law of Electromagnetic Induction to measure the flow rate of liquid in a pipe. In the magnetic flowmeter pipe parts, a magnetic field is generated and channeled into the liquid flowing through the pipe.

As fluid flows through the magnetic field, conductive particles in the fluid create changes. This variation is used to measure and calculate the velocity of water flow through the pipe. When the fluid moves faster, more voltage is generated. The electronic transmitter processes the voltage signal to determine the liquid flow.

It is a key type of rate flow meter. It uses a multi-leaf motor rotor (turbocharger) to experience the average water flow of the fluid. Then it calculates the total flow or total output.

A meter that measures the total flow rate based on the efficacy of the fluid fluidity on the ultrasonic beam (or ultrasonic single pulse).

The thermal flowmeter sensor includes 2 sensing technology components. A speed sensor and a temperature sensor. They compensate and calibrate the gas temperature changes fully automatically.

The electric heater part of the instrument heats the speed sensor to a certain time constant higher than the temperature of the working condition. A stable temperature difference is generated between the speed sensor and the sensor that measures the temperature of the working condition.

When the temperature difference does not change, the kinetic energy consumed by the electric heater. It can also be said that the heat dissipation value is proportional to the mass flow rate of the passing gas. It is suitable for the measurement of single gas and a fixed proportion of multiple gases.

The basic principle is to use the Coriolis force caused by the fluidity of the fluid in the vibrating tube. The force can be measured immediately or indirectly to obtain the fluid mass flow.

Gas mass flow meter working principle

The thermal flowmeter is a flowmeter designed based on the principle of thermal diffusion.

That is, when the fluid flows through the heat-generating object, the heat loss of the heat-generating object is proportional to the flow rate of the fluid.

The sensors of the series flowmeter have two standards RTD,

one for the heat source, and one for measuring the temperature of the fluid.

When the fluid flows, the temperature difference between the two is linear with the flow rate,

and then the relationship is controlled by microelectronic control technology.

Converted to a linear output that measures the flow signal.
