Plug-in thermal gas mass flow meter

Intelligent plug-in thermal gas mass flow meter for measuring compressed air, hydrogen, oxygen, nitrogen, blast furnace gas, natural gas, etc.;

Plug-in thermal gas mass flow meter


Product Principle 

The sensor part of the thermal gas mass flowmeter consists of two reference grade platinum resistance temperature sensors. When the instrument is working, one sensor continuously measures the medium temperature T1; the other sensor self-heats to the medium temperature T2, which is used for the sense The fluid flow rate is called the speed sensor. The temperature T=T2-T1, when the fluid flows, the gas molecules collide with the sensor and take away the heat of T2, so that the temperature of T2 decreases. To keep T constant, the supply current of T2 is increased. The faster the flow rate, the more heat is removed, and the gas flow rate and the added heat have a fixed function relationship. This is the principle of constant temperature difference.
