The thermal gas mass flow meter is not suitable for which conditions

The thermal gas flowmeter has many remarkable characteristics, which make it widely used in the field of gas flow measurement. The following are the main features of thermal gas flowmeters:

The thermal mass flowmeter is an device for measuring gas flow by using the principle of thermal diffusion. The sensor consists of two reference thermal resistors (RTDS). One is the speed sensor RH, and the other is the temperature sensor RMG, which measures the temperature change of the gas. When the two RTDS are placed in the measured gas, one sensor RH is heated and the other sensor RMG is used to sense the measured gas temperature. As the gas flow rate increases, the airflow carries away more heat, and the temperature of the sensor RH drops.

The medium of one of the two tubes of the thermal gas mass flowmeter does not flow, and the medium of the other tube flows. By comparing the Coriolis force of two pipes to obtain the flow rate, it is convenient to eliminate the natural vibration of the pipeline, the vibration of the fluid itself and other factors that affect or interfere with the measurement.

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.

With the development of new energy technology, natural gas is more and more widely used in many new energy industries, and the thermal gas mass flowmeter has become a suitable instrument for measuring high pressure gas measurement. Below we analyze from the perspective of product performance and installation cost, why the thermal gas mass flowmeter can become a suitable low degree meter in high pressure natural gas measurement.

Direct measurement of gas mass, without temperature, pressure compensation of gas flow measurement instrument, it represents the development trend of gas flow measurement. The thermal mass flowmeter sensor part is composed of two reference platinum resistance temperature sensors, using a bridge loop, one sensor measures the fluid temperature, and the other sensor is a heating element, maintaining a constant temperature difference higher than the fluid temperature, that is, when the gas flows through the heating element, the heat is taken away, and the heat is proportional to the flow rate of the gas and the density of the gas. To maintain a fixed temperature difference between the two temperature sensors requires the circuit to provide more power to the heating element, and the amount of output power in the circuit is related to the mass of the fluid, thus measuring the flow rate.
