Compress Air Thermal Mass Gas Flow Meter Air Flowmeter Manufacturer
Compress Air Thermal Mass Gas Flow Meter Air Flowmeter Manufacturer Description:
Thermal gas mass flowmeter is designed based on the principle of thermal diffusion. The instrument uses constant temperature difference method to measure gas accurately.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 maintains a constant temperature difference with the process temperature. The greater the mass flow rate of 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.
