In practical applications, thermal mass flowmeters require careful attention to various factors to ensure accurate and reliable measurement of fluid flow rates. Here are some key considerations for the practical application of thermal mass flowmeters:

The thermal mass flowmeter is an device for measuring gas flow by using the principle of thermal diffusion. The sensor consists of two reference thermal resistors (RTDS). One is the speed sensor RH, and the other is the temperature sensor RMG, which measures the temperature change of the gas. When the two RTDS are placed in the measured gas, one sensor RH is heated and the other sensor RMG is used to sense the measured gas temperature. As the gas flow rate increases, the airflow carries away more heat, and the temperature of the sensor RH drops.
