High accuracy RS485 compress gas thermal mass flow meter
1. Product introduction
The thermal mass flowmeter consists of sensor and signal analysis, processing and control unit. One part of the sensor measures the temperature while 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 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.
2. Main Features
1. Thermal gas mass flowmeter does not need temperature and pressure compensation for gas flow measurement. It can measure the mass flow rate or standard volume flow rate of the gas.
2. Wide range ratio. It can measure gas with flow rate from 0.5Nm/s to 100Nm/s, and also can be used for gas leak detection.
3. Easy installation and maintenance. On-site conditions permit, installation and maintenance without shutdown can be realized.
