What is a mass flow controller?

The mass flow controller (abbreviated as MFC) not only has the function of the mass flow meter. More importantly, it can automatically control the gas flow. That is, users can set the flow according to their needs. MFC automatically keeps the flow constant at the set value. Even if the system pressure fluctuates or the ambient temperature changes. It will not deviate from the set value.

Simply put, the mass flow controller is a steady flow device. It is a gas steady flow device that can be set manually or connected to a computer for automatic control.

What is the principle of a mass flow controller?

The mass flow controller is composed of a flow sensor, a diverter channel, a flow regulating valve and an amplifying controller.

The flow sensor uses the principle of capillary heat transfer thermometry to measure the mass flow of gas (without temperature and pressure compensation).

The flow signal measured by the sensor heating bridge is sent to the amplifier for amplification. The amplified flow detection voltage is compared with the set voltage, and then the difference signal is amplified to control the regulating valve. The closed loop controls the flow through the channel to make it equal to the set flow.

The flow divider determines the flow of the main channel.

A regulated power supply and a digital voltmeter are provided on the flow display instrument matched with the mass flow controller. Set potentiometer, peripherals, built-in conversion and three-position valve control switch, etc.

How to understand the flow unit of a mass flow meter/mass flow controller?

Gas mass flow units are generally expressed in sccm (Standard Cubic Centimeter per Minute, standard milliliters per minute) and slm (Standard Liter per Minute, standard liters per minute).

This means that under different conditions of use, the indicated flow rate is the flow rate in the standard state.

The standard state requirements are: air pressure—101325Pa (760mm Hg); temperature—0℃ (273.15K). This is an important difference between this meter and other flow meters, and it is also the difference between sccm and slm from mL/min and L/min.

For most users, the expression method of volume flow is very habitual. Easy to use. But there are also users who need to know the mass of the medium flowing in a unit of time (such as g/min). This requirement is very easy to achieve. Because the gas density in the standard state is a constant. , Can be easily found, so it can be realized by simply doing a multiplication (multiplying the density by several slm). Therefore, the volume flow rate in the standard state is equivalent to the mass flow rate.

When to use a mass flow meter and when to use a mass flow controller?

Generally speaking, when only measuring or monitoring the flow, use a mass flow meter.

When you need to control the flow, use a mass flow controller.

For some measurement occasions, both can be used. For example, when measuring the flow capacity of capillary tubes, use a mass flow meter when measuring flow at a constant pressure.

When measuring pressure with constant flow, a mass flow controller is required.

Note that when the mass flow controller is in the cleaning state. It can also be used as a mass flow meter. It’s just that the pressure drop is larger than that of ordinary mass flow meters.

What are the main advantages of mass flow meters/mass flow controllers?

(1) Flow measurement and control are not inaccurate due to temperature or pressure fluctuations.

For most flow measurement and control systems, it is difficult to avoid system pressure fluctuations and environmental and medium temperature changes. For ordinary flow meters, fluctuations in pressure and temperature will cause larger errors. For mass flow meters/mass flow controllers, it can generally be ignored.

(2) Automation of measurement control

The mass flow meter/mass flow controller can output the flow measurement value as a standard electrical signal output.

In this way, it is easy to realize digital display of flow, automatic measurement of accumulated flow, automatic data recording, computer management, etc.

For mass flow controllers, automatic flow control can also be realized.

Generally, the analog MFC/MFM input and output signals are 0~+5V or 4~20mA, and the digital MFC/MFM is also equipped with RS232 or RS485 digital serial communication ports. It can be easily connected to a computer for automatic control.

(3) Accurately control flow

The mass flow controller can accurately control the given amount of gas. This is particularly useful for flow control in many processes, and for proportional control of different gases.

(4) Wide scope of application

• With a wide working pressure range, our products can range from vacuum to 10MPa.
• Can be applied to a variety of gas media (including some corrosive gases, such as HCL).
• There is a wide flow range. The minimum flow range of our products can reach 0～5 sccm, and the maximum flow range can reach 0～200 slm.
• The resolution of the flow display can reach 0.1% of the full scale.
• The flow control range is 2~100% of full scale (range ratio is –50:1). Therefore, it is widely used in many fields.

What are the disadvantages of mass flow meters? What are the fears of using mass flow controllers?

Relative to cheap rotameters, the main disadvantage of mass flow meters is that they are relatively expensive.

There are four fears when using a mass flow controller:

First fear of dust. If dust enters the flowmeter, it will block the sensor and the diverter, causing measurement errors. It is required to install a filter before the air inlet;

The second fear is that liquid and oil will enter the MFC. It will cause loss of control. If the outlet of the MFC is connected to a liquid tank, a check valve must be added to the outlet of the MFC to prevent the liquid from returning;

The third fear of using moist corrosive gas. Moist and corrosive gases will rust the stainless steel and cause damage to the MFC channel. Therefore, it is required to dry the gas and the MFC piping system before using the corrosive gas;

Fourth, fear not operating in accordance with safety rules when using highly corrosive, flammable, explosive, toxic, and other hazardous gases. It may cause product damage and other more serious losses. Correct use and safe operation are important to every user.

Can mass flow controllers be used to control corrosive and special gases? How to choose sealing materials?

Mass flow controllers can be used to control various gases, including corrosive gases and special gases.

But it should be noted that for the use of corrosive gas and special gas, it is necessary to select the model and sealing material appropriately.

When ordering, the user needs to make a special statement to the supplier that the gas is used. In order to avoid serious losses due to wrong selection or selection of sealing materials.

Generally, the wet materials of the gas mass flow controller that contact the working gas are 316L stainless steel, polytetrafluoroethylene, and sealing materials. Sealing materials are divided into two categories: metal seals and rubber seals.

The material of the metal seal is generally corrosion-resistant materials such as stainless steel, gold or nickel.

In principle, MFC with metal seal can be used for any gas. Including various corrosive gases and special gases.

For strong corrosive gases such as boron tribromide, boron trichloride, hydrogen fluoride, and metal oxide gases used in MOCVD, it is recommended to use metal-sealed MFC.

Due to the high price of metal-sealed MFCs, rubber-sealed MFCs are usually used where the requirements are not high.

If there is no special statement, all MFCs are sealed with fluorine rubber. It can be used for most acidic and alkaline corrosive gases. For example, it can be used for halogenated dry gases such as hydrogen chloride.

Some other special corrosive gases require special rubber.

Ammonia-Ammonia resistant rubber, such as ethylene-propylene rubber, neoprene rubber or nitrile rubber is required. Organic solvent vapor (acetone, toluene, etc.)-silicone rubber is required. Boron tribromide, boron trichloride, hydrogen fluoride, etc.-need to use perfluoro rubber.

Why is magnetic flow meter calibration necessary?

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.

2 Magnetic flow meter calibration methods

At present, there are 2 solutions for Magnetic flow meter calibration: direct and indirect.

Direct Magnetic flow meter calibration is the excitation coil inspection method. This method is also known as the “dry standard” method of electromagnetic flowmeters. Indirect calibration is the external clamp-on ultrasonic flowmeter calibration method. Also known as the “non-contact measurement method”.

However, in the “dry standard” method, the standard coil is directly designed into the meter body of the flowmeter. The performance of its resistance and other indicators cannot be traced regularly.

As a result, it is impossible to determine whether the measurement characteristics of the standard coil change after a period of time. Therefore, “dry standard” is difficult to effectively realize the traceability of the value.

Compared with the “dry standard” method of detection. The external clamp ultrasonic flowmeter is capable of non-stop flow and non-cutting of pipes. The advantages of on-site Magnetic flow meter calibration are not affected by the temperature, pressure, and density of the fluid being measured.

The external ultrasonic flowmeter calibration method is used for on-site calibration. The inspector should first check whether the input of the key parameters that affect the accuracy of the measurement built in the flowmeter converter is correct.

Ask the staff about the daily flow rate, and observe and calculate the average flow rate of the flowmeter over a period of time.

Big data compared with standard equipment in the laboratory according to the standard table. Enter the pipe diameter of the standard meter and the flow meter to be inspected. Calibration coefficients, outer diameter, wall thickness and other parameters similar to the flow rate. According to the flowmeter’s online operating instructions on-site actual measurement input.

The cumulative flow method is used when calculating the indication error. Read the cumulative value of the flow of the standard meter and the meter under inspection for a certain period of time in three times. As the standard value of the measurement standard meter and the displayed value of the tested flow meter. Each measurement time is 30min.

Conditions permit or when the flow rate changes significantly within a day. Three flow points with obvious differences can be measured.

How do you calibrate a magnetic flow meter?

• Select the corresponding pump according to the pipe diameter and flow rate for the verification test;
• If the system uses compressed air power. Turn on the air compressor to reach the air source pressure required by the system. To ensure the rapid switching of the commutator and the normal operation of the clamp meter;
• After the flowmeter is correctly installed and connected. It should be energized and preheated for about 30 minutes under the requirements of the verification regulations;
• If the high tank water source is used, check whether the overflow signal of the stabilized water tower appears.
• Before the formal test. According to the requirements of the verification regulations, use the verification medium to circulate the time in the pipeline system. At the same time, check whether there is any leakage in the sealing parts of the pipeline;
• Before starting the formal verification, the verification medium should be filled with the flowmeter sensor to be tested. Then turn off the downstream valve to adjust the zero position;
• When starting the verification, first open the valve at the front of the pipeline. Slowly open the valve behind the flow meter under test to adjust the flow at the verification point.
• During the calibration process, the flow stability of each flow point should be within the 1% ~ 2%-flow method, while the total amount law can be within 5%. When completing the verification process of a flow point, the temperature change of the verification medium should not exceed 1℃. When completing all the verification processes, it should not exceed 5℃. The pressure downstream of the inspected flowmeter should be high enough to ensure that no flashing and cavitation occur in the flow pipeline (especially in the reduced diameter);
• After each test, the valve at the front end of the test pipeline should be closed first. And then the pump should be stopped to avoid emptying the voltage stabilizing facility. At the same time, empty the remaining verification medium in the test pipeline. Then turn off the control system and the air compressor.

Ultrasonic water flow meter

The ultrasonic water flow meter is a commonly used water flow meter. It can be installed with an external clamp, Insertion installation, pipeline installation, etc. Hand-held clamp-on ultrasonic flowmeters are very popular for their ease to use.

RFQ

Leak detection method:

Use a portable ultrasonic flowmeter to test the pipeline of the entire system, which can reveal the location of the leak.

The portable flow meter allows the operator to compare the flow rate and the total flow rate at various points in the system.

The low flow at the site indicates that there is a leak nearby. This method is non-invasive and does not require cutting the pipe.

Two ultrasonic flowmeters, one is installed on the water outlet pipe of the reservoir, and the other is installed at the critical intermediate position where the pipe is spread from underground to the ground.

As long as the measurement of the two flowmeters is the same, it means that there is no water leak in the buried pipe network. On the contrary, there is water leak.

Extended reading: Industrial VS Residential inline water flow meters

When a single conduit in a complex piping configuration is compromised, it can be challenging to locate the precise point where the leak occurred. If you observe an increase in overall water consumption without making any changes, it is likely that a pipe has cracks or cracks.

How does an ultrasonic flow meter work?

Transit time Ultrasonic Flow Meter adopts the measurement principle of time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.

The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.

By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

Notes:
V measure fluid velocity
M ultrasonic reflection times
D pipe diameter
θ The angle between the ultrasonic signal and the fluid
T up The time when the downstream sensor transmits the signal to the upstream
T down Time from upstream sensor to downstream
ΔT = T up – T down

You can refer to the following to select the appropriate Industrial inline water flow meter.

Mechanical water flow meter

A mechanical water flow meter relies on the kinetic energy of the water flow to drive the metering mechanism to work. The water flowing through the water pipe impacts the water meter impeller and then drives the gear to rotate, without electricity.

The mechanical water flow meter is currently used less, mainly due to the following reasons:

There are many vulnerable parts, and the existence of the movable part impeller is easy to cause fouling of itself and the measuring cavity. Even blockage, especially when the water quality is poor. Therefore, the reliability and stability of the work are relatively low;

The movable part of the impeller shaft core is easy to wear after a long time or high flow rate operation. Especially when the water quality is corrosive. Therefore, the durability of work is low, and the service life is relatively short;

The presence of the impeller in the measurement chamber will produce a large pressure loss. Reduce the transmission capacity of the heating pipe network. In particular, it brings difficulties to the transformation of the old pipe network;

The accuracy of flow measurement is relatively low. There are also certain requirements for the flow rate of the fluid. Can not effectively measure when the flow rate is low.
