What are the advantages and precautions of the thermal gas mass flow meter?

Thermal gas mass flowmeter based on the principle of thermal diffusion, using constant temperature difference method designed, is a gas measurement instrument.

The thermal gas mass flowmeter is an instrument that measures fluid flow based on the principle of heat conduction. This instrument accurately measures the mass flow of gas by using the constant temperature difference method.

Thermal gas mass flowmeter can be used to measure any gas that does not contain condensed liquid in various shapes and materials (such as round pipe, square pipe, rectangular pipe, etc., diameter from 8mm-10000mm or larger, all kinds of metal, plastic, cement material), it does not need temperature and pressure compensation, directly measure the mass flow of fluid.

The application of thermal gas mass flow meter in various industries

In the industrial field, companies need to use natural gas, hydrogen and other gas in many process production, sometimes also need oxygen, nitrogen, argon and other made of gas, this part of the gas cost needs to be controlled and monitored, and the selection of monitoring instruments need to consider various issues:

Like the flue gas, this medium has a higher temperature, contains more impurities such as solid dust, the general application of large caliber, flow rate range is relatively wide, so the measurement is more difficult, so in the selection and use of flue gas flow timing should pay attention to the characteristics of the power plant flue wind speed, pay attention to the principle of choosing sensors, It is also necessary to pay attention to the wear resistance, corrosion resistance, dirt resistance and high temperature resistance of the sensor, and select the appropriate measurement position to ensure the measurement accuracy.

Due to the continuous development of thermal gas mass flow meter is based on the principle of thermal diffusion, that is, the use of fluid flow through the heated object, the heated object of the heat dissipation of how much with the fluid flow rate into a certain proportional relationship. Specifically, the flow meter’s sensor has two standard and the RTD, has been used as a heat source, has been used to measure the fluid temperature, the fluid flows through, the heat loss of the heat source and the size of the flow into a non-linear relationship, the thermal gas mass flowmeter can be converted into a measurement of this relationship to measure the flow rate of the signal of the linear output.

The selection of flue gas flowmeter is a complicated but critical process, which is directly related to the accuracy of measurement results and the reliability of equipment. Here are some of the main factors to consider in the selection process:

In order to solve the problem of leakage caused by poor measurement accuracy or inability to measure below the lower limit of the instrument, a new type of thermal gas mass flowmeter is developed based on the theory of forced convection heat transfer and the principle of hot wire anemometer. The sensitivity of the instrument is greatly improved and the dead zone of the instrument is reduced by using microfilament structure in the sensitive element and the velocity measuring heating element.

Thermal gas mass flowmeter, gas flow measurement without temperature and pressure compensation, measurement is convenient and accurate.

Thermal mass flowmeters offer several advantages and disadvantages, which are important to consider when selecting a flow measurement solution. Here are some of the key advantages and disadvantages:

When selecting a thermal mass flowmeter, several important factors should be taken into consideration to ensure it meets the requirements of the application and provides accurate and reliable measurements. Here are key points to pay attention to:

The thermal gas mass flowmeter is an instrument that uses the principle of heat conduction to measure flow. The instrument adopts constant temperature difference method for gas mass flow sensor part consists of two reference platinum resistance temperature sensors. Using a bridge loop, one sensor measures the flow temperature and the other maintains a constant temperature difference above the fluid temperature, allowing flow measurement under high temperature and high pressure conditions.

Thermal gas mass flowmeter has a wide range of applications in many fields, its high precision, rapid response and stability characteristics make it in a variety of gas flow measurement occasions can play an excellent performance, for the development of various industries to provide more reliable technical support.

Biogas, as a renewable and clean energy source, is widely used in power generation, heating, chemical engineering and other fields. However, biogas has a complex composition (containing CH₄, CO₂, H₂S, water vapor, etc.) and is characterized by corrosiveness, high humidity and large pressure fluctuations, which poses higher requirements for flow measurement. How to choose the right biogas flowmeter? The following five key factors will be analyzed for you!
