Background
Thermal gas mass flowmeters are instruments that measure the flow of gas using the principle of thermal diffusion. The sensor consists of two reference level thermal Resistors (RTDs). One is a velocity sensor RH and one is a temperature sensor RMG which measures the change in gas temperature. When the two RTDs are placed in the gas being measured, with sensor RH being heated, the other sensor RMG is used to sense the temperature of the gas being measured. As the gas flow rate increases, the gas flow carries more heat away and the temperature of the sensor RH drops. The thermal flowmeter is a flow meter designed based on the principle of thermal diffusion, namely, the heat loss of a heating object is in a certain proportional relation with the flow of fluid when the fluid flows through the heating object. The sensor of the series flowmeter has two standard level RTDs, one is used as a heat source and the other is used for measuring the temperature of fluid, when the fluid flows, the temperature difference between the two is in linear relation with the flow, and the relation is converted into the linear output of a flow measuring signal through a microelectronic control technology.
