Thermal Gas Mass Flow Meter Insertion Type Natural Gas Oxygen
Pipeline Type Micro Gas Flow Meter
The sensor part of the thermal gas mass flow meter consists of two
reference level platinum anode temperature sensors. During
instrument operation, one sensor continuously measures the medium
temperature T1; Another sensor self heats to a temperature higher
than the medium temperature T2, which is used to sense the fluid
flow rate and is called a velocity sensor. The temperature
AT=T2-T1, T2>T1. When there is fluid flowing through, the gas
molecules collide with the sensor and take away the heat of T2,
causing the temperature of T2 to decrease. To keep T constant, it
is necessary to increase the power supply current of T2. The faster
the gas flows, the more heat is taken away. There is a fixed
functional relationship between the gas flow rate and the increased
heat, which is the principle of constant temperature difference
