Turbine Flow Meter Working Principle

Turbine meters are simple to operate and maintain,

and in-service worldwide as a reliable, cost-effective method,

for achieving accurate flow measurement.

Turbine flow meters are designed to maximize throughput,

and minimize pressure drop, maintain high flow rates over an extended flow range,

and offer pulse output that is linear to the flow rate.

The turbine meters also minimize fiscal measurement uncertainty,

by delivering high-frequency pulse resolution,

to account for minute increments of the flow rate.

Turbine flow meters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream.

Blades on the rotor are angled to transform energy,

from the flow stream into rotational energy.

The rotor shaft spins on bearings.

When the fluid moves faster, the rotor spins proportionally faster.

Turbine flow meters now constitute 7% of the world market.

Shaft rotation can be sensed mechanically or by detecting the movement of the blades.

Blade movement is often detected magnetically,

with each blade or embedded piece of metal generating a pulse.

Turbine flowmeter sensors are typically located external to the flowing stream,

to avoid material of construction constraints that would result,

if wetted sensors were used.

When the fluid moves faster, more pulses are generated.

The transmitter processes the pulse signal to determine the flow of the fluid.

Transmitters and sensing systems are available to sense flow,

in both the forward and reverse flow directions.

Turbine flow meter equation

The relationship between volumetric flow rate of the turbine flowmeter and the frequency of the pulses generated by the pickup sensor can be expressed in the form of the equation:

f = kQ

f = Frequency of pulses generated by pickup sensor(Hz, equivalent to pulses per second)
Q = Volumetric flow rate (e.g. litres/min)
k = “K” factor of the turbine meter (e.g. pulses per litre)

Turbine Meter K-Factor
The turbine meter measures volumetric flow, however the pulses produced vary depending on the meter. The variation is accounted for by a K-factor. The K-factor is the number of pulses per unit volume. It is primarily determined by the size and type of the turbine meter. Due to manufacturing tolerances, the actual K-factor can vary between similar models. The K-factor is applicable only to the fluid for which the meter was calibrated in the factory.

How does A Magnetostrictive Sensor work?

  1. When the sensor of the magnetostrictive level transmitter works, the circuit part of the sensor will excite a pulse current on the waveguide wire.
  2. When this current propagates along the waveguide wire, a pulsed current magnetic field is generated around the waveguide wire.
  3. There is a float outside the sensor rod of the magnetostrictive liquid level gauge. This float can move up and down along the rod with the change of liquid level.
  4. Inside the float there is a set of permanent magnetic rings. When the pulsed current magnetic field and the magnetic ring magnetic field generated by the float want to meet. The magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the float.
  5. This pulse is transmitted back along the waveguide wire at a fixed speed and detected by the detection mechanism.
  6. The position of the float, that is, the position of the liquid surface can be accurately determined by measuring the time difference between the pulse current and the torsional wave.

They can measure both levels and the interface between two media. Continuous level measurement in liquids and solids with guided wave radar sensors. These transmitters work by sending a microwave pulse through a sensor cable or rod. The signal hits the surface of the liquid, and travels back to the sensor, and then to the transmitter housing. Based on the time taken by the signal to travel down the sensor and back up again. The electronics integrated into the transmitter housing determine the filling level.

Hydrostatic level transmitter

Hydrostatic level transmitters are also called submersible level transmitters, or pressure level transmitters. For Hydrostatic level measurement, Continuous level measurement in liquid applications with pressure sensors. These transmitters help in determining the fluid level of a container. By measuring the pressure of the resting body of the fluid within it.

Ultrasonic level transmitter

Ultrasonic Level Indicator, also called Ultrasonic level sensor, or ultrasonic level transmitter. In this type of transmitter, an ultrasonic transducer is mounted at, or near the top of a container containing liquid. The transducer sends out an ultrasonic pulse. The pulse hits the surface of the liquid and gets reflected. The sensor then calculates the fill level based on the time between the transmitted and received signal.

How does a level transmitter work?

The level of the liquid medium in the container is called the liquid level. And the instrument that measures the liquid level is called the liquid level transmitter. Level transmitter is a kind of level instrument. There are two types of level transmitterss, one is continuous and the other is point-off. The continuous level transmitter is a real-time monitor of the height of the liquid in the container. The point type, which generally takes two points, high and low, and outputs an alarm signal when the medium in the container reaches these two points.The types of liquid level transmitters is very wide. Specific include: magnetic flap liquid level gauge, tuning fork vibration type, differential pressure type, pressure type. Ultrasonic, magnetostrictive liquid level gauge, magnetic flap, radar and so on.
Levels of media such as: water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.
Level measurement transmitter are used in a myriad of applications that require level measurement within containers or tanks. These transmitters often find their application in material handling, food and beverage, power, chemical, and water treatment industries.

What is radar level transmitter?

Radar level transmitter is a kind of liquid level transmitter which uses the principle of radar operation.
Radar Level Sensor also called radar level transmitter, are the indicating transmitter for liquid level.
Non-contact Continuous level measurement in liquids and solids with free space radar sensors.
RADAR (Radio Detection And Ranging) is a device which can detect the presence of faraway objects by obtaining a reflection of electromagnetic waves emitted from the device itself. Although invented much earlier, wide deployment of radar was done by Britain during the Second World War to detect oncoming German bombers.
Radar level measurement is a safe solution. Even under extreme process conditions (pressure, temperature) and vapors. Various antenna versions for every kind of radar applications are available.
In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.

How does capacitance level measurement work?

Capacitive level sensor is a device that converts the change of the measured object position into capacitance. Capacitance level gauge has simple structure, high resolution, reliable operation and fast dynamic response. It can be measured non-contact, and can work under harsh conditions such as high temperature, radiation and strong vibration. It has been applied in various fields of industrial and agricultural production. But traditional capacitive level meters all use analog circuits.

How Does a Coriolis Flow Meter Work?

As shown in the figure, when a mass point with a mass of m moves at a speed υ in a pipe rotating at an angular velocity ω on the p axis, the mass point is subjected to the acceleration and force of two components.

a. Normal acceleration is the centripetal force acceleration αr, its magnitude is equal to ω2r, and the direction is toward the P axis;
b. Tangential acceleration αt is Coriolis acceleration, its magnitude is equal to 2ωυ, and the direction is perpendicular to αr.
Due to the compound motion, Coriolis Fc=2ωυm acts in the αt direction of the particle, and the pipe acts on the particle with a reverse force -Fc= -2ωυm.

When a fluid with a density of ρ flows at a constant speed υ in a rotating pipe, any pipe with a length of Δx will experience a tangential Coriolis force of ΔFc.


In the formula, A-the internal cross-sectional area of the pipeline. Since the mass flow rate is δm, δm=ρυA.
And so


Therefore, the mass flow can be measured by directly or indirectly measuring the Coriolis force generated by the fluid flowing in the rotating pipe. This is the basic principle of the Coriolis mass flowmeter.

However, it is difficult to generate Coriolis force by rotating motion. The current products are all replaced by pipe vibration, which is a thin-walled measuring tube fixed by two broken ends. At the midpoint, it is excited at or near the resonance of the measuring tube. The fluid flowing in the tube generates Coriolis force, which causes the two halves of the measuring tube to be deflected in opposite directions. Electromagnetic method is used to detect the amount of deflection to obtain the mass flow rate.

The fluid density will affect the vibration frequency of the measuring tube. The density has a fixed relationship with frequency. Therefore, mass flow meters can also measure fluid density.

Advantages and Disadvantages of coriolis flow meter


  • The Coriolis mass flow meter directly measures the mass flow rate with high measurement accuracy.
  • It can measure a wide range of fluids, including high-viscosity liquids, slurries containing solids, liquids containing trace gases, and medium and high-pressure gases with sufficient density.
  • The measuring tube has a small vibration amplitude and can be regarded as a non-moving part, and there are no obstructions and moving parts in the measuring pipe.
  • It is not sensitive to the flow velocity distribution of the upflow, so there is no requirement for upstream and downstream straight pipes.
  • The measured value is not sensitive to the fluid viscosity, and the change of fluid density has little effect on the measured value.
  • Multi-parameter measurement can be done, such as measuring density at the same time, and deriving the concentration of solute in the measurement solution from this.


  • The instability of the zero point of the Coriolis mass flowmeter results in zero drift, which affects the further improvement of its accuracy. Many types of meters have to divide the total error into two parts, the basic error and the zero point instability measurement.
  • Coriolis mass flow meters cannot be used to measure low-density media and low-pressure gases; the gas content in the liquid exceeds a certain limit (varies by model), which will significantly affect the measured value.
  • Coriolis mass flowmeters are more sensitive to external vibration interference. In order to prevent the impact of pipeline vibration, most models of Coriolis mass flowmeters require relatively high installation and fixation of flow sensors.
  • It cannot be used for larger pipe diameters, and is currently limited to 150 (200) mm or less.
  • The inner wall of the measuring tube is worn, corroded, or deposited and scaled, which will affect the measurement accuracy, especially for the Coriolis mass flowmeter of the thin-walled tube.
  • The pressure loss is relatively large, which is equivalent to that of volumetric meters. Some Coriolis mass flow meters are even 100% larger than volumetric meters.
  • Most models of Coriolis mass flow meters are larger in weight and volume.
  • Expensive. The overseas price is 5,000 to 10,000 US dollars for a set, which is about 2 to 5 times that of the electromagnetic flowmeter of the same caliber; the Chinese price is about 2 to 8 times that of the electromagnetic flowmeter.

Coriolis flow meter installation

Installation Requirements for Coriolis Mass Flowmeters

When choose Flowmeter, many enterprises will choose Coriolis mass Flowmeter under reasonable cost. Under the correct installation, Coriolis mass Flowmeter can directy measure the mass and density of fluid. Only reasonable installation can ensure the accuracy and stability of mass Flowmeter.

1. Conventional of Coriolis Mass Flowmeter Installation

At least 0.6 m distance between the sensor and a large transmitter or motor. Since the sensor depends on the electromagnetic field. It is necessary to avoid installing the sensor near the large interference electromagnetic field. In addition, the installation position should be carefully selected to avoid vibration as far as possible.

2. Installation Direction

The requirements of the process and the location of the process pipeline have determined the installation direction of most sensors.While the sensor installation angle does not affect the flowmeter operation, the following recommendations should be considered to the extent possible:

  • (1) When measuring the liquid. The sensor housing shall be mounted downward to avoid air gathering in the flow tube;
  • (2) When measuring the gas. The sensor housing shall be mounted upward to avoid condensation water gathering in the flow tube;
  • (3) When measuring liquid slurry. The sensor shall be mounted vertically, like a flag, to avoid the accumulation of particles in the flow tube. The process medium should flow from the bottom up to avoid the jet tube.

3. Valves

In order to facilitate Flowmeter zero adjustment, the downstream sensor should be installed globe valve. To facilitate batch operation, sensors and globe valves should be as close as possible to the receiving container.

Hose should not be installed between sensor and globe valve to avoid batch error caused by expansion or compression. Also, control valves can be installed downstream to prevent vaporization or emptying of the medium.

4. Flow direction of mass flow meter installation

No matter what flow direction, the flow sensor can accurately measure the flow rate. The normal flow direction of the fluid is indicated by arrows on the general sensor.

5. Gas&liquid two-phase flow

If the process medium produces a gas-liquid two-phase flow, the sensor housing should be installed down or on a vertical pipe. This installation can effectively avoid the accumulation of gas in the medium in the flow tube.

In loading and unloading metering applications, the sensor housing should be mounted upwards or vertically. One-way valves should be installed downstream of the sensor to prevent medium reflux. One-way valves should be installed as close as possible to the sensor.

In some cases, the process medium can not be completely excluded from the pipeline. And flag installation is generally recommended.

When Coriolis mass Flowmeter is installed, the direction of installation is very important. The direction of installation is determined according to the position of the process pipeline arranged on the spot.

Reasonable installation can ensure the long-term stable work of Coriolis mass Flowmeter. Installation Requirements for Coriolis Mass Flowmeters.

Four Installation Methods of Coriolis Mass Flowmeters

I. Normal installation, medium/large Coriolis mass flowmeter

It is recommended to release and empty the gas that may be stored in the Coriolis mass Flowmeter pipeline of Shanghai Automation instrument Co., Ltd before installation.

 II. Inverted installation, medium/large Coriolis mass flowmeter

It is recommended to use an inverted installation to measure gas (e.g. steam). Because only in this way, the liquid that may be stored in the Coriolis mass Flowmeter can be released and emptied.

III. Flag type installation, medium/large Coriolis mass flowmeter

Flag installation is the installation of Coriolis mass Flowmeter perpendicular to horizontal line.

Flag type mounting is recommended to measure the suspension and liquid and solid biphasic liquids.

For example, for liquids that are easy to solidify under temperature change, for liquids with high viscosity, it is necessary to empty the liquid left in the measuring pipe after measurement.

Flag mounting will not affect the measurement accuracy of any type of liquid measured. but the direction of the measurement flow must be bottom-up.

IV. Miniature Pipe Size Coriolis Instrument Installation

Sino-Inst small size Coriolis mass Flowmeter has a very small flow range and high accuracy requirements. In this way, stable mounting plates and supports are necessary. The mounting plate and Coriolis mass Flowmeter must be completely flat without any space.

If not, use horizontal bolts to adjust the balance. The small size Coriolis mass flowmeter is installed as follows:

Features of Remote Magnetic Sewage Flow Meter

  • Electromagnetic flowmeter is an instrument for measuring volumetric flow. Flow measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow rate, and the measurement accuracy is high.
  • There are no obstructions and moving parts in the measuring tube, which will not cause additional energy loss or blockage. Therefore, the energy-saving effect is significant, and it is especially suitable for the measurement of liquid-solid two-phase flow such as sewage, mud, mineral pulp, coal water slurry, paper pulp, etc.
  • The electromagnetic flowmeter has no mechanical inertia and is sensitive. It can measure instantaneous pulsating flow and has good linearity.
  • Installation requirements are low. The straight pipe section required by the sensor is relatively short, generally the first 5D and the rear 3D (D is the inner diameter of the selected instrument).
  • The sensor part only has the lining and the electrode in contact with the medium. As long as the electrode and the lining material are selected reasonably, it can resist corrosion and abrasion, ensuring long-term use.
  • When the power is off, the EEPROM can protect the set parameters and accumulated values.
  • The converter uses a low-power single-chip microcomputer to process data. It uses SMD electronic components and surface mount SMT technology. Reliable performance, high precision, low power consumption, and zero point stability. LCD display, display cumulative flow, instantaneous flow, flow rate, flow percentage and other parameters.
  • It adopts multi-electrode structure with high accuracy. Equipped with ground electrode, no grounding ring is needed, which saves cost.
  • The low-frequency rectangular wave excitation improves the stability of the flow. The power loss is low and the low flow rate is superior.
  • Two-way measurement system. It can measure forward flow and reverse flow.

Electromagnetic Flow Meter for Sewage

According to the situation of the wastewater treatment site, there are two general wastewater discharge methods. One is to discharge through pipes, and the other is to discharge through ditches. The two types of flow meters selected are therefore different.

1.Waste water is used for pipeline discharge, and most of them choose electromagnetic flowmeter to measure. Because there are no obstructions in the sensor, there is no fear of debris in the medium.

But need to pay attention to the medium must be full. If the pipe is not full, a pipe must be used to lead a section of the sinking pipe to ensure that the flowmeter is in a full pipe.

Note that the electromagnetic flowmeter cannot be installed at the drain of the pipeline, and the length of the straight pipe must meet the requirements of the flowmeter.

Extended Reading: Guide: Magnetic Flowmeter Installation

2.Wastewater is used for ditch discharge, mostly using ultrasonic open channel flow meters.

A measuring groove is installed at the discharge port, and an ultrasonic probe is installed directly above the groove. In this way, the flow of wastewater flowing through can be measured. This instrument generally uses 24V power supply, output: 4-20MA.

When selecting the electromagnetic flowmeter for waste water, it is necessary to know the temperature of the medium, the pressure of the medium, the flow range of the medium, the composition of the medium, the power supply requirements, and the on-site installation requirements. The key point of the selection is to choose which product to measure well. The second is to consider the convenience of installation, operation and maintenance. Finally, the product price can be considered.

Wastewater/Sewage Flow Meter Calibration

A flow meter’s deviation from the standard can be measured in two ways: with a master meter or by weighing mass flow.

Master meters are calibrated to peak accuracy by specified, accredited laboratories.

These labs are ones that are certified by the National Institute of Standards and Technology (NIST). Subsequently, this means that flow meters. Which are calibrated to master meter accuracy in such a lab will be backed by NIST certification and traceability.

The second method of flow meter calibration involves weighing the amount of fluid that flows through the meter, during the calibration procedure. This is typically done using a supremely accurate weigh scale, which must also be approved by NIST.

This method is often regarded as the most accurate way to measure the volume of flow.

Flow meters can also be calibrated in the field, also known as “wet” calibration.

However, this method is frequently scrutinized because it lacks the involvement of national standards.

Additionally, field calibrations are usually not an option in most applications. Because challenging an installed flowmeter with a given volume of water is just not practical.

Insertion magnetic flow meter principle

All MAG Meters operate under the same fundamental principle of classical physics (Faraday’s Law of Electromagnetic Induction):

E = CONSTANT x B x D x V

The law states that the magnitude of the voltage (E) induced in a conductive medium, moving through a magnetic field is directly proportional to the strength of the magnetic field (B), the path length between the probes (D), and the velocity of the medium (V).

In principle and implementation, it is possible to fix all parameters except velocity.

Thus a MAG Meter responds only to “velocity” and is extremely insensitive to changes in fluid conditions (density, viscosity, etc.) and application constraints (pressure, temperature, and mechanical vibrations, as well as fluid pulsation).

The operation of a MAG Meter is completely analogous to an electrical generator.

A voltage is induced in a conductor that is moving at right angles through a magnetic field.

The faster the conductor moves, the more voltage is generated.

Choice of installation environment

  1. It should be installed at the lower part of the horizontal pipeline and vertically upwards, avoid installing at the highest point of the pipeline and vertically downwards;
  2. It should be installed on the rising part of the pipeline;
  3. Installation in the open discharge pipe should be installed at the lower part of the pipe;
  4. If the pipeline drop exceeds 5m, install an exhaust valve downstream of the sensor;
  5. The control valve and shut-off valve should be installed downstream of the sensor, not upstream of the sensor;
  6. The sensor must not be installed at the inlet and outlet of the pump, it should be installed at the outlet of the pump.
  7. Keep away from equipment with strong fields, such as large motors and large transformers.
  8. There should be no strong vibration in the installation place, and the pipeline should be firmly fixed. The ambient temperature should not change much.
  9. The installation environment should be easy to install and maintain.

Choice of installation location

The installation location must ensure that the pipeline is always filled with the fluid under test.
Choose a place where the fluid flow pulse is small, that is, away from the pump, valves, elbows and other local resistance parts.

When measuring two-phase (solid, liquid or gas, liquid) fluids, choose a place that is not easy to cause phase separation.

Avoid negative pressure at the measurement site.

The diameter or circumference of the side pipe is easy to measure, and the ovality should be small.

Length of straight pipe

The length of the straight pipe section on the upstream side of the sensor installation pipeline should be greater than or equal to 10D, and the downstream side should be no less than 5D (D is the diameter of the pipeline being tested).

The flow control valve should be installed on the pipe under test on the upstream side of the sensor, and the flow control valve should be installed on the downstream side of the sensor. When measuring, usually the flow control valve should be fully open.

Installation method

Vertical installation, when the sensor is inserted into the pipeline, it should be perpendicular to the central axis of the pipeline, and the included angle with the pipe section is less than 50. It is suitable for measuring clean media with small pipeline vibration.

There are two ways to insert the insertion point of the electromagnetic flow sensor. One is to insert at 1/4 of the inner diameter of the pipe. The other is to insert at 1/2 of the inner diameter of the pipe.

Correctly weld the mounting base to the pipe. Clean up welding slag and burrs on the mounting base of the pipe under test.

Turn off the upstream flow control valve or use a low-pressure water supply.

Install the DN50 ball valve on the mounting base. Note that the long cavity of the ball valve faces upwards. Check whether the ball valve can be fully opened and closed. If there is any problem, repair it. Install the compression threaded seat, compression nut and rubber sealing ring on the ball valve. Loosen the positioning screw and the compression nut, and insert the sensor through the ball valve into the pipe under test. Tighten the compression nut and the positioning screw, and at the same time, pay attention to the insertion direction of the sensor direction sign and the fluid flow direction.

Insertion depth

(1) When selecting the electrode to insert to the average flow rate, the average flow rate point is about H=0.25D from the pipe wall (D: pipe inner diameter) according to the pipeline turbulent flow conditions. Press the handle to make the insertion rod enter the pipe H deep. (L2 at this time = original L2-H)

(2) After confirming that the insertion depth is correct, turn the flow direction rod to make its connection parallel to the centerline of the pipeline. At this time, the connection between the two electrodes will be perpendicular to the centerline of the pipeline. That is, the connection between the electrodes is perpendicular to the flow rate.

(3) After adjustment, first tighten the lock nut firmly, and then tighten the three locknuts separately. One of their functions is to ensure that the insertion rod is not pushed out by the pressure in the tube. The other is to ensure that the insertion rod does not vibrate.

(4) During actual on-site installation, the insertion depth is only allowed to be 0.25D, which is a quarter of the diameter of the pipe. The insertion depth is 0.5D, which is the center of the pipe.

(5) Loosen the fastening screws under the junction box. Rotate the junction box to the position you are satisfied with and tighten the nuts.

The Insertion flowmeter is a type of flowmeter divided by structure. It includes various flowmeters with different working principles.

Usually, the flowmeter and the pipeline are flanged. Only when the processing pipeline is cut off is allowed to be disassembled, repaired, and replaced. This has a great impact on the reliable operation of the system. The Insertion flowmeter fundamentally solves this defect. Although the measurement accuracy is slightly lower. But on some large-caliber occasions, Insertion flowmeters have been used to measure the total amount of fluid.

There are many forms of Insertion flowmeters that have been promoted. According to the working principle of Insertion flowmeter detection heads, they can be divided into Insertion turbine, Insertion vortex, Insertion electromagnetic, uniform velocity tube, and thermal flowmeter. The number of measuring points of the Insertion flowmeter can be divided into two categories: point flow type and runoff type.

The accuracy of the magnetic flowmeter has been calibrated by the calibration line when it leaves the factory. However, at the use site, due to environmental conditions, fluid characteristics, and instrument damage such as component damage. It often causes instrument operation failures. Therefore, the electromagnetic flowmeter needs calibration. Ensuring accurate flow meter performance is an inestimable part of business planning and costing.

More Featured Insertion flowmeters

At present, there are many kinds of Insertion flowmeters in use. According to the working principle of the Insertion flowmeter detection head, it can be divided into Insertion turbine, Insertion vortex, Insertion electromagnetic, Insertion ultrasonic, and Insertion target flowmeter.

The correct choice of the flowmeter is of great significance for flow measurement. Choosing different flow meters under the same working conditions will definitely have a considerable difference in the final measurement results.

If the initial selection is improper, it may even lead to the inability to perform quantitative measurements and cause damage to the instrument. Therefore, it is necessary for users to have a correct understanding of how to choose a suitable flow meter. Knowing some basic selection methods will help make mistakes when choosing meters.

In order to ensure the use of the flow meter in the production site process. The choice of flowmeter, in general, must be determined according to the medium that needs to be measured at the production site.

The advantages of the insertion vortex flowmeter are particularly good anti-vibration performance, no zero drift, and high reliability. Through a large number of waveform analyses and frequency spectrum analyses on the vortex flowmeter for a long time, the probe shape, wall thickness, height, probe rod diameter, and matching piezoelectric crystals are designed.

Insertion Vortex Flow Meter

It adopts an advanced numerical control lathe for processing. It ensures the coaxiality and smoothness of processing and other technical parameters and cooperates with special processing. It overcomes the common problem of the influence of the inherent self-oscillation frequency of the vortex flowmeter on the signal.

The insertion vortex flowmeter is mainly used for the flow measurement of large-caliber gas, liquid, and steam medium fluids in industrial pipelines in various industries.

It is characterized by small pressure loss, a large measuring range, and high accuracy. It is almost not affected by fluid density, pressure, temperature, viscosity, and other parameters when measuring volume flow under working conditions.

Insertion ultrasonic flowmeter can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam shift method, Doppler method, and cross-correlation method according to the principle of signal detection. , Spatial filtering method and noise method, etc.

Ultrasonic Insertion Flow Meter

Ultrasonic flowmeters are the same as electromagnetic flowmeters. Because the flow channel of the instrument is not equipped with any obstructions, it is an unobstructed flowmeter. It is a type of flowmeter suitable for solving difficult problems in flow measurement. Especially in large-caliber flow measurement. The advantages.

Insertion ultrasonic flowmeter is mainly used in petroleum, chemical industry, metallurgy, electric power, water supply, and drainage, and other fields.

The structure of the Insertion turbine flowmeter is an explosion-proof design. It can display the total flow, instantaneous flow, and the percentage of flow full scale. The battery adopts a long-term lithium battery. The battery life of a single-function integrator can reach more than 5 years, and the battery life of a multi-function indicator can reach more than 12 months.

Turbine Insertion Flow Meter

Insertion turbine flowmeter can display many flow units, including cubic meters, gallons, liters, standard cubic meters, standard liters, etc. The fixed pressure and temperature parameters can be set to compensate for the gas. For occasions where the pressure and temperature parameters do not change much, the instrument can be used for fixed compensation accumulation.

Insertion turbine flowmeters are mainly used in metering and control systems in the fields of petroleum, chemical industry, metallurgy, scientific research, and so on.

The Insertion target flowmeter is based on the traditional target flowmeter. With the development of new sensors and microelectronics technology, a new type of capacitive force induction flow Insertion target flowmeter has been developed. It has the characteristics that the flowmeter has no movable parts such as an orifice plate and vortex street. At the same time, it has high sensitivity and accuracy comparable to positive displacement flow meters. The measuring range is wide.
