Thermal Mass Flow meter Applications

Thermal mass flow meters are meters that measure the flow of gases using the principle of thermal diffusion. The sensor consists of two reference-grade RTDs. One is a speed sensor RH, and the other is a temperature sensor RMG that measures the temperature change of the gas. When these two RTDs are placed in the gas to be measured, where the sensor RH is heated, another sensor RMG is used to sense the measured gas temperature. As the gas flow rate increases, the airflow takes more heat and the temperature of sensor RH drops.
