Working Principle of Micro Motion Flow Transmitter

The micro motion flow transmitter works by measuring the flow rate of liquids and gases using the Coriolis Effect. This means that when a fluid flows through a tube, it causes the tube to vibrate in a specific way. The sensor inside the micro motion flow transmitter detects these vibrations and calculates the mass flow rate of the fluid.

Imagine a tube filled with water. As the water flows through the tube, it causes the tube to twist and turn, similar to a twisting rope. The sensor within the micro motion flow transmitter detects these twists and turns and uses them to measure the amount of water flowing through the tube. This allows the transmitter to accurately measure the mass flow rate of the fluid. Making it an important tool for industries that rely on accurate flow measurements.

In simpler terms, the micro motion flow transmitter works like a detective. It senses the movements of the fluid flowing through the tube and uses them to determine how much of the fluid is flowing. This makes it an essential device for ensuring precise and accurate flow measurements in a variety of industries.

Types of Micro Motion Flow Transmitter

There are a few different types of micro motion flow transmitter available, each with its own unique features and benefits. These include:

• Fork vibrating flow meters: These have a sensor that vibrates like a tuning fork to detect the movement of the fluid.
• Straight tube flow meters: These have a straight tube that the fluid flows through, which makes them ideal for applications where the fluid is very viscous.
• Dual tube flow meters: These have two tubes that vibrate in opposite directions, which makes them very accurate and precise.

Each type of flow meter has its own strengths and weaknesses, so it’s important to choose the right one for your needs.

For example, a straight tube flow meter might be best if you’re measuring the flow of a thick liquid. While a dual tube flow meter might be best if you need extremely precise measurements.

By understanding the different types of micro motion flow transmitter available, you can choose the one that’s right for your specific application.

Different Types of Flowmeters Flowmeters are devices used to measure the flow rate of different liquids, steam or gases in a line. They come in different types, such as mechanical, ultrasonic, and magnetic flowmeters.
Mechanical flowmeters use a positive displacement flow measuring device to determine the volume of the fluid passing through. Ultrasonic flowmeters use an ultrasonic sensor to determine the velocity of the fluid, while thermal flowmeters use heat to measure the flow rate. Orifice plates and magnetic flowmeters are some of the most common types of flowmeters used in industry.
Understanding the different types of flowmeters and their principles of operation is essential to selecting the right measuring device for a particular application.

RFQ Digital FlowMeters

What is a Flow Meter?

A flow meter is a device that measures the amount of liquid, steam or gas that passes through a specific point in a pipe or conduit. It is used in various industries to monitor and control the flow of fluids in pipelines, such as water, oil , gas, or chemicals.

Flow meters can be mechanical, electronic, or ultrasonic, and they work by measuring the velocity, volume, or mass of the fluid.

Flow meters are essential for ensuring that fluid flow rates remain within acceptable limits. And they help prevent damage to equipment and systems due to overloading or underloading. They are also critical in maintaining product quality and process efficiency.

Types of Flowmeters

There are various types of flowmeters used to measure fluid flow, including mechanical, electronic, and ultrasonic. Each type measures the flow rate of a fluid in a different way. Each type of flowmeter has its advantages and disadvantages.

We’ll take a look at the 5 main types of flowmeters that can be found on the market today. Includes differential pressure flowmeters, velocity flowmeters, positive displacement flowmeters, mass flowmeters and open channel flowmeters. More types of flowmeters from Wikipedia.

Differential Pressure (DP) Flowmeters

Differential Pressure (DP) Flowmeters measure fluid flow by detecting the pressure drop across an throttle placed in the flow path, such as an orifice plate, venturi tube, or flow nozzle. The greater the flow rate, the higher the pressure drop, and the flow rate can be calculated based on the pressure difference. DP Flowmeters are widely used due to their simplicity and low cost, and they can be used to measure both liquids and gases.

There are several types of DP Flowmeters, each with its unique design and advantages. Here are some of the most common types:

• Orifice Plate Flowmeters: They have a circular plate with a hole in the middle that creates a pressure drop as the fluid flows through it.
• Venturi Flowmeters: They have a conical shape that narrows down the flow path, which causes an increase in fluid velocity and a decrease in pressure.
• Flow Nozzle Flowmeters: They have a converging inlet section, a throat section, and a diverging outlet section that create a pressure drop across the nozzle.
• Pitot Tubes: They measure the fluid velocity by detecting the pressure difference between the stagnation point and the point where the fluid flow is parallel to the tube’s axis.

Each type of DP Flowmeter has its advantages and disadvantages, and the best choice depends on the specific application requirements.

Positive Displacement (PD) Flowmeters

Positive Displacement (PD) Flowmeters measure fluid flow by trapping and measuring the amount of fluid that moves through the meter. The principle of operation is based on the movement of the fluid through a chamber of fixed volume, causing a displacement of the fluid. The flow rate is calculated based on the number of times the chamber is filled and emptied. PD Flowmeters are highly accurate and suitable for measuring low flow rates of both viscous and non-viscous liquids.

There are several types of PD Flowmeters, each with its unique design and advantages. Here are some of the most common types, along with their advantages and disadvantages:

More details about: PD Flow Meters Selection and Application | Oil-Liquid

Velocity Flowmeters

Velocity Flowmeters measure fluid flow by determining the velocity of the fluid as it flows through the meter. The principle of operation is based on the relationship between the velocity of the fluid and the pressure difference created by the fluid’s motion. Velocity Flowmeters are commonly used for measuring high flow rates of fluids such as water, steam, and gases, and they are often less expensive than other types of flowmeters.

Here are some of the most common types of Velocity Flowmeters along with their advantages and disadvantages:

Mass Flowmeters

Mass Flowmeters measure the mass flow rate of fluids passing through them, rather than measuring volume or velocity. They work on the principle of thermal dispersion or Coriolis effect, and they can measure the flow rate of both liquids and gases accurately. Mass Flowmeters are highly sensitive and provide accurate readings even with changes in fluid properties, making them ideal for a wide range of industrial applications.

Coriolis Meters:

Coriolis Meters measure fluid flow using the Coriolis effect. The meter consists of a vibrating tube, and as the fluid flows through the tube, it causes a change in the tube’s vibration frequency, which is measured by sensors.

The advantages of Coriolis meters include high accuracy and stability, excellent repeatability, and the ability to measure a wide range of fluids, including liquids and gases.

However, they can be costly, and their performance can be affected by the presence of solid particles or gas bubbles.

Thermal Mass Flow Meters:

Thermal Mass Flow Meters measure the mass flow rate of fluids by detecting the heat transfer from a heated element to the fluid. As the fluid flows over the heated element, it cools it down, and the change in temperature is measured by temperature sensors.

The advantages of Thermal Mass Flow Meters include high accuracy, the ability to measure both liquids and gases, and their simplicity of design.

However, they can be affected by changes in fluid temperature and viscosity, and they may require recalibration if the fluid properties change.

Open Channel Flowmeters

Open Channel Flowmeters are used to measure the flow rate of liquids in open channels, such as rivers, streams, and irrigation canals. They work by using a primary device, such as a flume or weir, to create a constriction in the channel, which causes the liquid to rise and flow through the device. The flow rate is then determined by measuring the height of the liquid above the device and using a formula to calculate the flow rate.

How to select a flow meter?

Here are some of the key parameters that can affect the selection of a flowmeter for a particular application:

1. Fluid type and properties, such as viscosity, density, and corrosiveness
2. Flow rate range and required accuracy
3. Operating conditions, such as temperature, pressure, and fluid velocity

What Is Turndown Ratio in Flow Meters? In simple terms, turndown ratio refers to the range of flow rates that a flow meter can accurately measure. This ratio is a crucial factor in selecting the right flow meter for your application, as it determines the meter’s ability to measure low and high flow rates with precision and accuracy.

Choosing a flow meter with a high turnover ratio can save you money and increase efficiency by eliminating the need for multiple flow meters or reducing maintenance and calibration costs. In this blog post, we will explore turnover ratio in flow meters, its importance, and how it impacts various industries.

RFQ Flow Meters

Definition of turndown ratio

So, what exactly is turndown ratio?

Well, it’s the measurement range of a flow meter from the highest to the lowest flow rate it can accurately measure. Essentially, it tells you how much the flow rate can be turned down or decreased while still maintaining accurate readings.

For example, a flow meter with a turndown ratio of 10:1 can accurately measure flow rates from 100 L/H down to 10 L/H.

This ratio is an important consideration when selecting a flow meter for your application, as it determines the meter’s versatility and ability to handle varying flow rates.

A higher turndown ratio means more flexibility and potentially cost savings, as you may not need multiple flow meters for different flow rates.

Why is Turndown Ratio important?

In flow measurement, the turndown ratio indicates the range of flow over which the flowmeter can measure with acceptable accuracy. It is also known as adjustable range. This is very important when selecting a flow meter technology for a specific application.

If the airflow to be measured is expected to vary between 100,000 cubic meters per day and 1,000,000 cubic meters per day. The turndown ratio for a specific application is then at least 10:1. Therefore, the meter requires at least a 10:1 turndown ratio.

Formula for calculating Turndown Ratio

The turndown ratio can be expressed as:
TR = Q(max)/Q(min)

TR = Regulation Ratio
Q(max) = maximum flow
Q (min) = minimum flow

Example calculation

If the gas to be measured varies between 100000 m3/day and 1000000 m3/day.
This particular application has TR = 10:1.
The TR of the required flow meter should be at least 10:1
If the flow meter has a maximum flow rate of 2000000 m3/day, then the required turndown ratio (TR) will be 20:1

Typical turndown ratios for various flowmeters

The examples here are for gas flow, but the same gauge type can be used for liquids, with similar turndown ratios.

Different types of flow meters have varying turnover ratios. Here are some common flow meters and their typical turnover ratios:

• Differential Pressure Flow Meters: 10:1 to 100:1
• Turbine Flow Meters: 10:1
• Magnetic Flow Meters: 20:1 to 100:1
• Coriolis Flow Meters: 10:1 to 100:1
• Ultrasonic Flow Meters: 100:1 to 1000:1
• Vortex Flow Meters: 10:1 to 100:1
• The turndown ratio of the thermal mass flow meter is 1000:1.
• The actual adjustment ratio of the orifice meter is 3:1.

It’s important to note that these are general ranges and actual turnover ratios may vary depending on the specific model, size, and operating conditions. When selecting a flow meter, it’s crucial to consider the turnover ratio and ensure that it can accurately measure the flow rate needed for your application.

What is pressure drop in a pipe? Pressure drop is the decrease in pressure that occurs as fluids flow through pipes due to friction and other factors. When we choose and use various flowmeters, we may all hear the parameter of pressure loss or pressure drop.

It’s important to know how to calculate pressure drop in pipes, as it can help you troubleshoot issues, optimize your system’s performance. In this blog, we’ll show you how to calculate pressure drop in pipes and provide tips to minimize it in your system. Let’s dive in!

RFQ

5 Factors Affecting Pressure Drop

In industrial settings, pipes are often used to transport liquids, gases, and other materials over long distances. When fluids flow through pipes, they experience pressure drop due to various factors, which can affect the efficiency of the system and even cause equipment failure.

In an industrial pipe system, several factors contribute to pressure drop, including the flow rate, pipe diameter, pipe length, fluid properties (like density and viscosity). And the presence of fittings and valves. These factors must be carefully considered when designing or troubleshooting an industrial pipe system to ensure that it operates safely, efficiently, and reliably.

In this section, we’ll explore each of these factors in more detail and discuss their impact on pressure drop in industrial pipes.

Calculation of Pressure Drop

Calculating pressure drop in a pipeline involves several steps, including:

• Determine the flow rate of the fluid in the pipeline.
• Determine the properties of the fluid, such as density and viscosity.
• Measure the pipe length, diameter, and roughness.
• Determine the number and type of fittings and valves in the pipeline.
• Select the appropriate pressure drop equation based on the specific pipeline conditions and design.
• Calculate the Reynolds number to determine if the flow is laminar or turbulent.
• Use the selected pressure drop equation to calculate the pressure drop.
• Compare the calculated pressure drop with the maximum allowable pressure drop to ensure that the pipeline operates safely.

It’s important to note that pressure drop calculations may need to be repeated several times to ensure that the pipeline design meets the required pressure and flow rate specifications. It’s also important to ensure that accurate and up-to-date data is used in the calculation to ensure the safety and efficiency of the pipeline.

Pressure Drop Equations

Pressure drop equations are mathematical formulas that engineers and designers use to calculate the pressure loss in a pipeline. There are many different equations, but three of the most common are Bernoulli’s equation, the Darcy-Weisbach equation, and the Hazen-Williams equation.

• Bernoulli’s equation
• Darcy-Weisbach equation

Online Pressure Drop Calculators and Software

Online pressure drop calculators and software have made it easier than ever to calculate the pressure drop in a pipeline. These tools provide users with an easy and efficient way to input pipeline data and receive accurate pressure drop calculations.

Online calculators typically require the user to input pipeline data such as flow rate, pipe diameter, length, fluid density and viscosity, and fittings and valve information. The software then uses algorithms and equations to provide an estimate of the pressure drop in the pipeline.

These tools are particularly useful for engineers, technicians, and operators who need to quickly and accurately calculate pressure drops for a wide range of pipeline applications.

For example: Pressure Drop Online-Calculator

Flow Meter Pressure Drop

Flow Meter Pressure Drop, also known as Pressure loss, is one of the key indicators of flow meters.

Flow Meter Pressure Drop is used to describe the pressure difference (P1-P2) before and after the flow meter input (P1) and output (P2). It is also the minimum pressure difference to ensure the normal operation of the flowmeter. It is one of the basic parameters of the flowmeter.

The pressure loss of the flowmeter generally increases with the increase of the flow rate. Also affected by the solution. For example, the pressure loss of flowmeters based on ultrasonic flowmeters and MEMS (micro-electromechanical systems) is much smaller than that of vortex flowmeters and differential pressure flowmeters.

Featured Inline Flow Meters

So is there any flowmeter that does not cause pipeline pressure loss?
Yes. Ultrasonic flowmeter, clamp-on sensor, does not need to cut the pipeline, and will not affect the pressure of the pipeline.

Understanding the Pressure Drop of the pipeline helps us to design the pipeline system reasonably.

The Pressure Drop of the flowmeter is also an important parameter to consider. The pressure loss of the flowmeter will cause energy consumption, which is an important parameter to characterize the performance of the flowmeter. It is also more and more people’s attention and become one of the important indicators of flow meter selection.

Vertical Flow Meters refers to a type of flow meter installed in vertical pipes. Can Flow Meters Be Installed Vertically? We all take this into consideration when installing flow meters. In fact, most flow meters can be installed vertically. However, certain measurement conditions also need to be met. Next, let’s analyze together.

RFQ Flow Meters

Electromagnetic flowmeter is the most widely used type of flowmeter. Can the electromagnetic flowmeter be installed vertically?

vertical installation of magnetic flow meter

Electromagnetic flowmeters can be installed horizontally or vertically. However, vertical installation needs to pay attention to the following aspects, whether it is installed at the water inlet or the water outlet.

Standard installed in the middle of the vertical position where the water flows upwards. This installation complies with gravity.
If it is installed downstream, it will not be a full pipe, and the water flow from bottom to top is always full. This facilitates accurate measurement of the flow meter.
The straight pipe section is required to be 10D in front and 5D in back to ensure the use and accuracy requirements of the electromagnetic flowmeter.

Electromagnetic flowmeter vertical installation requirements:

1. Installed at the inlet of the pipeline (that is, upstream), so that the pipeline is always full.
2. The electromagnetic flowmeter should be installed in the lower part of the horizontal pipeline, vertically upward. Avoid installing at high places and vertically downward positions in the pipeline.
3. Requirements for straight pipe section: inlet/outlet straight pipe section: inlet ≥ 10×DN; water outlet ≥ 5×DN
4. In order to facilitate the detection of the flowmeter, a bypass channel is set in the measuring pipeline.
5. Grounding point requirements: In order to make the instrument work reliably, improve the measurement accuracy, and not be disturbed by strong external electromagnetic fields, the sensor should be well grounded, and the grounding resistance should be less than 10 ohms.

Precautions when choosing the installation location of the electromagnetic flowmeter:

1. Try to avoid ferrous objects and equipment with strong electromagnetic fields (such as large transmitters and generators).
2. The flow meter should be installed at the rear of the pump, never on the suction side, and the valve should be installed on the downstream side of the flow meter.
3. It should be installed in a dry and ventilated place as much as possible to avoid sun and rain. Avoid ambient temperatures above 60°C and relative humidity above 95%.
4. Choose a place with convenient installation and maintenance and convenient activities.

Can ultrasonic flow meters be installed vertically?

Ultrasonic flowmeters can be installed vertically.
However, there are conditions. If the pipeline is vertical, then the vertical installation of the ultrasonic flowmeter requires the liquid flow to be bottom-up. It is also best to ensure that the pipeline is full during the measurement period. Otherwise, the error is quite large.
Do not install vertically if the liquid flow is from top to bottom.

Can the turbine flowmeter be installed vertically?

The turbine flowmeter has many good functions, and it can have different application characteristics in different environments. Today we will talk about can the turbine flowmeter be installed vertically?

First of all, what we need to know is that it is very important to choose a suitable installation location to ensure the good use of the turbine flowmeter. In general, vertical installation and horizontal installation are both possible.

However, vertical installation needs to ensure that the turbine flowmeter is installed just above the direction of the liquid and in the direction of the liquid.

Second, debugging is required after installation. In this way, various problems that may arise during use can be avoided. The service life of the flowmeter is extended. And there is no need to worry about machine failure.

Can the vortex flowmeter be installed vertically?

The fluid flows from top to bottom, and the vortex flowmeter can be installed vertically. Just make sure there are no air bubbles in the tubing.

But one thing to remember is to make it clear with the supplier in advance when purchasing, so as not to affect its use in time. Although the vortex flowmeter can be installed vertically, you must pay attention to the installation direction of the flowmeter during installation, and it cannot be reversed.

When the medium measured by the vortex flowmeter is different, its installation direction is also different. For example, when measuring liquid flow, the installation direction needs to be from bottom to top. When measuring gas flow, the installation direction needs to be installed from top to bottom.

Can the orifice flowmeter be installed vertically?

When the orifice flowmeter is installed vertically, attention should be paid to the flow direction of the gas. Gas flows from bottom to top, which is also an important consideration for vertical installation of orifice flowmeters. Of course, it is also possible to flow from top to bottom.

In theory, when measuring gas flow, the orifice flowmeter is installed horizontally. The installation position of the flow sensor should be selected at a high place in the pipeline. to make sure the tube is full. It is not recommended to install in the low part of the pipeline. Because liquid will accumulate at the bottom of the pipe, the measurement will be inaccurate.

Can the mass flow meter be installed vertically?

Mass flow meters can be installed on horizontal or vertical pipes. The mounting orientation depends on the application.

Mass flowmeters with some geometries (except for straight tubes) will accumulate some solid or gaseous matter in a certain installation orientation.

If it must be installed vertically and the fluid flows from top to bottom. Measures must be taken to ensure that gas cannot enter the sensor from the sensor inlet pipe.

Oilfield wastewater, the water that is extracted from oil wells along with crude oil. Usually contains oil, salt, mechanical impurities, dissolved oxygen and saprophytic bacteria. Pollution to the oil field and the surrounding environment. After treatment, it can be reinjected back into the oil layer to be used as an oil displacement agent. Most of the time, electromagnetic flowmeters are used to measure oilfield wastewater.

RFQ Flowmeters

Difficulties in Oilfield Wastewater Measurement

With the growth of oil demand and the improvement of oil extraction technology, the amount of oil extraction wastewater treatment is increasing day by day. Effective control of oil production wastewater pollution and the utilization of wastewater resources have become key issues facing oilfield development.

The first thing to do in wastewater treatment is to accurately measure the oil production wastewater. Only by accurately measuring the amount of wastewater can scientific and reasonable wastewater treatment and wastewater scheduling be carried out. After the wastewater is treated up to the standard, most of it will be used as mining injection water and re-injected into the formation.

Turbine flowmeters used in some early Oilfield Wastewater. The error between the instrument measurement data and the measurement tank data reaches more than 20%, which causes a great waste of on-site resources.

1. Oil production wastewater carries a large amount of suspended solids. The inner blades of the turbine flowmeter are easy to be jammed and damaged, and need to be dismantled and maintained regularly;
2. Turbine flowmeters used in different pipelines and process links are not universal. On-site instrument maintenance is difficult;
3. The flow rate of the 2-inch pipe is less than 70 cubic meters per day. The micro-flow turbine flowmeter cannot measure accurately;
4. The lower end of the coupling device is easy to accumulate impurities, which makes the measurement accuracy low. The tiny traffic of some sites cannot even be measured;
5. Oil production wastewater has a high temperature and contains different salts and other impurities. It is easy to corrode the turbine flowmeter.

Oilfield wastewater classification

Before sewage treatment, it is particularly important to determine its composition. The sewage on the oil field is divided into general sewage and drilling sewage:

Application of Electromagnetic Flowmeter in Oilfield Wastewater and Oilfield

The advantages and working principles of electromagnetic flowmeters have been mentioned in many pages. I won’t repeat it here.

Electromagnetic flowmeters play an important role in water irrigation, polymer injection and sewage metering in oil fields.

The use of electromagnetic flowmeters in the measurement of oilfield wastewater has the following advantages.

①The structure of the sensor is simple and reliable. The diameter is the same as that of the front and rear straight pipe sections. And there are no moving parts in the flow channel. There are no parts to block the flow of the measured liquid and save equipment. There will be no jamming or jamming;

② The measured medium flows through the measuring tube. There is almost no loss of pressure, which can significantly reduce the consumption of the driving force of the pump;

③ The output current and frequency of the electromagnetic flowmeter have a linear relationship with the measured flow. It is not affected by the measured medium (temperature, pressure, viscosity). Therefore, the electromagnetic flowmeter can be used to measure crude oil with sandy content or high water content only after being calibrated with water without modification;

④ Electromagnetic flowmeter has no mechanical inertia and quick response. Instantaneous pulsating flow can be measured. It is convenient for the monitoring of the production site.

Selection of Electromagnetic Flowmeter for Measuring Oilfield Wastewater

It is very important to choose the type of instrument including the magnetic flowmeter. Some failures of instruments in practical applications are caused by wrong selection or improper use. Therefore, after selecting an electromagnetic flowmeter, the following factors should be considered:

1. Aperture Selection

According to the process pipe diameter, pipe pressure and sewage flow provided by the sewage treatment plant. Choose an electromagnetic flowmeter with an appropriate diameter, and there is no need for pipe shrinkage and expansion at the installation site.

2. Selection of Liner and Electrode Materials

Electromagnetic flowmeters are mainly used to measure fluid flow with a conductivity greater than or equal to 5 pressure S/cm. Different lining and electrode materials should be selected according to the corrosiveness, wear, temperature and condensation characteristics of the tested material and its bearing capacity.

3. Select the protection level

According to national standards, the sensor has two levels of protection: IP65 water jet type and IP68 submersible type. According to the actual installation position of the user in the low well, the sensor adopts IP68 dustproof submersible type.

4. Select other functions

(1) For the selected basic type, the electromagnetic flowmeter has LCD display, 4-20ma current output and 0-1khz frequency output. The function of the Rs-485 communication port should be added according to the communication requirements of the flowmeter and the computer.

(2) For sensors installed underground, split type should be selected.

More solutions for wastewater flow measurement

The flow of Oilfield Wastewater varies greatly, contains impurities, and is less corrosive, regardless of general sewage or drilling sewage. It contains many ions and has high conductivity. Combined with the unique characteristics of not being disturbed by external factors such as temperature, pressure and viscosity. Electromagnetic flowmeter is undoubtedly the most suitable choice for oil field sewage flow measurement.

In addition, in the sewage treatment process, large-diameter flowmeters are mostly split. One part is installed underground and the other part is installed on the ground. The small caliber is mainly integrated. In the water supply and drainage and sewage treatment industries, electromagnetic flowmeters, especially large-caliber electromagnetic flowmeters, have great advantages.

If you encounter a situation where the electromagnetic flowmeter is not applicable for Oilfield Wastewater. I think the target flow meter is a good choice. It is accurate in measurement, and the measurement structure is not affected by the physical characteristics of the medium temperature, pressure, conductivity, and the amount of impurities that are easily contained. The operation is stable and reliable, and it is resistant to high temperature, shock and wear. Long service life, easy to install and use.

A flow meter is an instrument used to measure and indicate the volume or mass of a gas or liquid. Simply put, it is an instrument used to measure the flow of fluid in pipes or open channels. Also known as flow indicator, liquid flow meter, flow sensor, etc.

Flowmeters are further divided into differential pressure flowmeters, rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. According to the medium, it can be divided into: liquid flowmeter and gas flowmeter.

RFQ Flowmeters

What is Flow Meter Calibration?

Flow meter calibration is carried out according to the verification regulations of various flow meters promulgated by the National Metrology Bureau.

For the flowmeters used, except for the standard throttling device, no experimental verification is required. The rest of the flowmeters are almost all verified when they leave the factory. During the use of the flowmeter, it should also be calibrated frequently.

The calibration methods of liquid flowmeter mainly include volumetric method, mass method, standard volume tube method and standard flowmeter comparison method.

The calibration methods of gas flowmeter mainly include sonic nozzle method, servo standard flowmeter comparison method and bell jar method.

Why is it important to calibrate a flow meter?

Most people recognize that a flow meter should be calibrated before it is put into service, but why is flow meter calibration so important?

The flow meter calibration process involves comparing the flow meter to a reference device used as a calibration standard. Calibration of reference equipment should be traceable to national or international standards. The next step involves adjusting the flow meter (if necessary) to counteract any errors.

If, like thousands of other facilities, flow meters are used in your process, it makes good business sense to ensure that the flow meters you use are giving you accurate and consistent information.

No matter what fluid you are metering, the liquid, gas or steam used in the process is most likely a valuable commodity. Accurate flow meter performance is therefore an invaluable part of business planning and costing.

At the same time, Calibration Flow Meters are also very important for the control of material consumption in our industrial production process. Can effectively improve production efficiency. reduce manufacturing cost.

Flow Meter Calibration vs. Recalibration

Flow Meter Verification (Verification): Refers to the process of identifying and confirming whether measuring instruments meet the statutory requirements. It includes inspection, marking and/or issuing a certificate.

Flow Meter Calibration (Calibration): refers to the determination of the value indicated by a measuring instrument or measuring system, or the value represented by a physical measuring tool or reference material, and the corresponding value reproduced by a standard under specified conditions. A set of operations on relationships.

After reading the definition, there must be some confusion, right?
We usually summarize the main differences between verification and calibration into nine aspects:

• Different purposes;
• Objects are different;
• According to different;
• Different in nature;
• The cycle is different;
• In different ways;
• The content of the certificate is different;
• Different conclusions;
• The authorities are different.

For quick understanding, we simply organize the following table:

How to Calibrate a Flow Meter？

Volume method

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

The figure below is a schematic diagram of the typical structure of the static volume method water flow verification device. Verify the flow meter with pulse output, and replace 21 for verification of other output flow meters.

The commutator 13 is used to change the flow direction of the fluid so that water flows into the standard container (the standard container 15 or 16 can be selected according to the flow rate). The pulse counting controller 21 is triggered when the commutator 13 starts. To ensure the simultaneous measurement of water and pulse signal counts.

When calibrating, use the pump to draw the test fluid from the liquid storage container into the high level water tank. Then through the school flow meter. If standard container 15 is selected, then close drain valve 17, open drain valve 18, and commutator 13 is placed in the position that makes water flow to standard container 16.

After the flow is stabilized, the commutator 13 is started. Water flow is changed into standard container 15 by standard container 16. At the same time, the trigger pulse counter accumulates the pulse number of the calibrated flowmeter. When the predetermined water volume or preset pulse number is reached, the commutator will automatically change direction. Water flow is changed into standard container 16 by standard container 15. Read off the volume V of the fluid that enters the standard container during this period of time from the scale on the reading glass tube of the container. Record the number of pulses N displayed by the pulse count control 21 for the flow meter being calibrated.

Compare the pulse number N of the calibrated flowmeter with the obtained standard volume V to determine the instrument constant and accuracy of the calibrated flowmeter. The instantaneous flow rate of the flowmeter is indicated by the frequency indicator 20 .

The system accuracy of this method can reach 0.2%.

Mass method

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

When calibrating, use a pump to draw the test fluid from the liquid storage container through the flowmeter to be calibrated and then enter the container containing the liquid. Measure the temperature of the fluid while weighing it out. It is used to determine the density value of the measured fluid at this temperature.

The volume of the fluid can be obtained by dividing the weight of the measured fluid by the density of the fluid at the measured temperature. Compare it with the volume indication (accumulated pulse number) of the meter. The meter constant and accuracy of the flowmeter to be calibrated can be determined.

The accuracy of this method system can reach 0.1%

standard volume tube method

The working principle of the standard volumetric 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 flowmeter to be calibrated and the standard flowmeter in series on the pipeline flowing through the test fluid. The error is calculated by comparing the two measured values. The accuracy of the standard flowmeter is 2 to 3 times higher than that of the schooled flowmeter.

Sonic Nozzle

The sonic nozzle gas flow standard device is a standard instrument based on the sonic nozzle. It is used to verify mass flowmeters, velocity flowmeters, volume flowmeters, rotameters, differential pressure flowmeters or other types of flowmeters. It is a standard device for measurement and testing units and large enterprises to measure and calibrate gas flowmeters.

According to the principle of aerodynamics, when the pressure ratio between the upstream and downstream of the factor nozzle reaches a critical state, the throat airflow reaches the peak velocity, and the mass flow through the nozzle also reaches the peak value. This value is only related to the parameter at the nozzle inlet and is not affected by changes in downstream conditions. Based on the above principles, this system uses the sonic nozzle as a standard meter to calibrate the measured flowmeter.

Field Calibration Method You Must Know

Many users search How to Calibrate a Flow Meter? In order to understand how to adjust the accuracy of the flowmeter in your own working conditions.

On-site “flow comparison” means that the flowmeter is compared with other “reference flows” on site.

For example, the measured value of the temporarily clamped ultrasonic flowmeter, the volume of the liquid that has been measured over the flow in the piping system, etc. can be used as the “reference flow”.

For the meaning of terms such as on-site calibration, comparison and verification, please refer to the standard definitions in relevant documents, and will not repeat them here.

In practice, many professionals have explored various on-site comparison methods and indirect inspection methods. There are mainly 3 types:

(1) Use the container weighing method comparison of storage containers, working containers, pools or weighing instruments in the process. The pool volume comparison method is often used by water supply companies. Water plants can obtain high comparison accuracy by taking advantage of the favorable conditions of large-volume clear water pools.

(2) Reserve a position in the pipeline of the flowmeter to be tested for the flowmeter comparison method of connecting the reference flowmeter.

(3) Ultrasonic flowmeter comparison method of Clamp-on ultrasonic transducer. Clamp-on ultrasonic flowmeter is one of the three most promising methods of flow measurement. Especially the measurement accuracy error of existing foreign products is < ± 0.5%. This is conducive to the establishment of high-precision comparative detection and on-site online calibration system. It is convenient for the metrology and verification department to go to the site for calibration and testing.

Turbine Flow Meter Installation Guidelines and Troubleshooting is compiled based on our Sino-Inst’s many years of experience in producing and supplying turbine flow meters.
Whether it is a liquid turbine flow meter or a gas turbine flow meter. In order to ensure that the measurement of the turbine flowmeter is accurate. The installation location and installation precautions must be correctly selected.

RFQ Turbine Flow Meters

Liquid Turbine Flow Meter Installation Guidelines

Installation Location

The sensor should be installed in a place that is easy to maintain, has no vibration in the pipeline, and is not affected by strong electromagnetic interference and heat radiation.

A typical installation piping system for a turbine flowmeter is shown in the figure.

1 – entrance;
2-valve;
3 – filter;
4 – air eliminator;
5- front straight pipe section;
6 – sensor;
7- rear straight pipe section;
8-Bypass

The configuration of each part in the figure depends on the situation of the measured object, not necessarily all of them.

Turbine flowmeters are sensitive to distortion of flow velocity distribution and swirling flow in the pipeline, and the flow into the sensor should be fully developed. Therefore, the necessary straight pipe section or flow regulator should be equipped according to the type of choke on the upstream side of the sensor, as shown in the table below.

If the condition of the upstream side choke is not clear, it is generally recommended that the length of the upstream straight pipe section is not less than 20D, and the length of the downstream straight pipe section is not less than 5D. If the installation space cannot meet the above requirements, a flow regulator can be installed between the choke and the sensor.

When the sensor is installed outdoors, measures should be taken to avoid direct sunlight and rain.

Installation Requirements for Connecting Pipelines

The sensor installed horizontally requires that the pipeline should not have a visually detectable inclination (generally within 5°). The verticality deviation of the sensor pipe installed vertically should also be less than 5°. The fluid direction must be upward when installed vertically.

Where continuous operation is required and the flow cannot be stopped, bypass pipes and reliable stop valves should be installed. When measuring, make sure that there is no leakage in the bypass pipe.

In the position where the sensor is installed in the newly laid pipeline, a short pipe is first inserted to replace the sensor. After the “line sweeping” work is completed and the pipeline is cleaned, the sensor is formally connected. Due to neglect of this task, it is not uncommon for wire sweeping to damage the sensor.

If the fluid contains impurities, a filter should be installed on the upstream side of the sensor. For those that cannot stop the flow, two sets of filters should be installed in parallel to remove impurities in turn, or self-cleaning filters should be selected.

If the measured liquid contains gas, a muffler should be installed on the upstream side of the sensor. The sewage outlet and air elimination outlet of the filter and muffler should lead to a safe place.

If the installation position of the sensor is at the low point of the pipeline, in order to prevent the impurities in the fluid from settling and stagnating. A discharge valve should be installed in the subsequent pipeline to discharge the precipitated impurities regularly.

The flow regulating valve should be installed downstream of the sensor, and the stop valve on the upstream side should be fully open when measuring. And these valves must not produce vibration and leak outward. For processes that may generate reverse flow, check valves should be added to prevent reverse flow of fluid.

The sensor should be concentric with the pipe, and the sealing gasket should not protrude into the pipe. Liquid sensors should not be installed at the highest point of the horizontal pipeline. In order to prevent the gas accumulated in the pipeline (such as mixed gas when the flow is stopped) staying at the sensor, it is not easy to discharge and affect the measurement.

The pipelines before and after the sensor should be supported firmly without vibration. For condensable fluids, thermal insulation measures should be taken for the sensor and its front and rear pipelines.

Installation Requirements

1. The pipe must be completely filled with liquid. It is important to keep the tubing completely filled with fluid at all times. Otherwise the traffic display will be affected. Measurement errors may result.
2. Avoid air bubbles. If air bubbles enter the measuring tube, the flow display may be affected, possibly causing measurement errors.

Straight pipe requirements

1. Generally
2. 90° elbow
3. Two 90° elbows on the same plane
4. Two 90° elbows on different planes
5. shrink tube
6. Expansion
7. Fully open valve
8. half open valve
9. If the condition of the upstream side choke is not clear, it is generally recommended that the length of the upstream straight pipe section is not less than 20D, and the length of the downstream straight pipe section is not less than 5D.
10. If the installation control cannot meet the above requirements, a rectifier can be installed between the baffle and the sensor.

Gas Turbine Flow Meter Installation Guidelines

When installing the Gas Turbine Flow Meter, the user must carefully read the following content. Because the condition of the installation of the flowmeter directly affects the accuracy and life of the flowmeter, and even safety issues during work.

• The installation work must be performed by personnel with corresponding pipeline equipment installation skills;
• The flowmeter should be installed in a place that is convenient for maintenance, no strong electromagnetic field interference, no mechanical vibration and thermal radiation influence;
• When the flowmeter is installed outdoors, there should be a cover on the upper part to prevent rainwater and hot sun from affecting the service life of the flowmeter;
• When the flowmeter is installed, it is strictly forbidden to conduct electric welding directly at its inlet flange to avoid burning the internal parts of the flowmeter;
• The newly installed or overhauled pipeline must be cleaned, and the flowmeter can be installed after removing the debris in the pipeline;
• The flowmeter can only be installed horizontally, not vertically. The fluid flow direction should be consistent with the direction marked on the housing. There should be a straight pipe section ≥ 2DN upstream of the flowmeter, and a straight pipe section ≥ 1DN downstream of the flowmeter. Straight pipe section, and the filter of the corresponding specification must be installed at the upstream of the flowmeter (≥2DN) (the company can match) to prevent excessive particulate impurities in the pipeline from entering the flowmeter and affecting the service life of the meter;
• The flowmeter should not be used in occasions where the flow is frequently interrupted and there is a strong pulsating flow or pressure pulsation;
• Ensure that the connection between the pipeline and the inlet and outlet of the flowmeter is coaxial, and prevent gaskets and welds from protruding into the pipeline, otherwise the flow profile will be disturbed;
• In order to facilitate the maintenance of the instrument, it is recommended to install the bypass pipeline according to Figure 6. Open the bypass when the instrument is maintained so as not to affect the normal production, and close the bypass pipeline during normal use.
• When the flowmeter is put into operation, the upstream valve of the flowmeter should be slowly opened, and then the downstream valve of the flowmeter should be slowly opened, so as to avoid the instantaneous air flow that will destroy the turbine flowmeter;
• The flowmeter must be reliably grounded as specified, but must not share the ground wire with the strong current system; during pipeline installation or maintenance, the ground wire of the electric welding system must not be overlapped with the flowmeter;
• During use, users are not allowed to change the connection method of the explosion-proof system and change the lead interface arbitrarily;
