Thermal mass flow meters are widely used for accurate measurement of gas flow in industrial process applications. Unlike conventional flow meters that measure volume flow, thermal mass flow meters directly measure the mass flow of gas, making them suitable for applications where stable and reliable gas measurement is required.

The meter operates based on the principle of thermal dispersion. As gas passes over the heated sensor, heat is carried away from the sensor, and the change in heat transfer is used to determine the mass flow rate.

Thermal mass flow meters are commonly used for compressed air, natural gas, nitrogen, oxygen and other gases. They are widely applied in factories, energy management systems, process control and gas monitoring.

With no moving parts and a wide measurement range, thermal mass flow meters provide a practical solution for continuous gas flow monitoring and energy management.
