XNTMF series thermal gas mass flowmeter

Working principle

The thermal gas mass flowmeter consists of two parts: sensors and signal analysis, processing, and control units. 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 that is always higher than the actual process temperature and maintains a constant temperature difference from the process temperature. The larger 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 measured gas can be obtained by measuring the energy of the heater.

Product Features

1. The quality flowmeter does not require temperature and pressure compensation for gas flow measurement, making the measurement convenient and accurate. The mass flow rate or standard volume flow rate of a gas.

2. Wide range ratio, capable of measuring gases with flow rates ranging from 100Nm/s to 0.1Nm/s, and can be used for gas leak detection.

3. Good seismic performance and long service life. The sensor has no moving parts or pressure sensing components, and is not affected by vibration on measurement accuracy.

4. Easy installation and maintenance. If on-site conditions permit, non-stop installation and maintenance can be achieved. (Special customization required)

5. Digital design. The overall digital circuit measurement is accurate and easy to maintain.

6. By using RS-485 communication or HART communication, factory automation and integration can be achieved.
