Thermal Gas Mass Flow Meter

Measuring principle Thermal mass flowmeter consists of sensor, signal analysis, processing and control unit.One part of the sensor measures temperature and the other part is used for heating.The former monitors the actual process temperature value;The latter maintains a constant temperature value so that it is always higher than the actual process temperature and remains constant with the process temperature.The greater the mass flow 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 measured gas can be obtained by measuring the energy of the heater.Product application. Compressed air/gas in boiler room or dryer/carbon dioxide gas in distillery/methane gas in sewage treatment plant and aeration/generated gas (such as argon, nitrogen, carbon dioxide, helium, oxygen)/gas leak detection
