KF100 series thermal gas flowmeter

The thermal mass flowmeter is composed of two parts: the sensor and the signal analysis, processing and control unit. One part of the sensor measures temperature, while the other part is used for heating. The former monitors the actual process temperature value; The latter maintains a constant temperature value, making it always higher than the actual process temperature and maintaining a constant temperature difference from that process temperature. The greater the mass flow rate of the gas, the greater the cooling effect, and the greater the energy required to maintain the differential temperature. Therefore, the mass flow rate of the gas being measured can be obtained by measuring the energy of the heater.
