The origin of the thermal gas mass flowmeter is from the hot wire anemometer. The temperature of the platinum heating wire has a proportional relationship with the change in the flow rate of the fluid: the faster the flow rate, the more heat is taken away.
Thermal gas mass flow meter is used to measure and control the gas mass flow meter, different from other gas flow meters, do not need to carry out pressure and temperature correction, directly measure the gas mass flow.
