TMF thermal gas mass flowmeter is an instrument that uses the principle of thermal diffusion to measure gas flow. The sensor consists of two reference level thermal resistors (RTDs). One is the speed sensor RH, and the other is the temperature sensor RMG that measures gas temperature changes. When these two RTDs are placed in the measured gas, the sensor RH is heated, and the other sensor RMG is used to sense the temperature of the measured gas. As the gas flow rate increases, the airflow carries more heat away, and the temperature of sensor RH decreases.
