Thermal gas mass flow meter

The thermal gas mass flowmeter is designed based on the principle of thermal diffusion, and uses the constant temperature difference method to accurately measure gases. It has the advantages of small size, high degree of digitization, easy installation, and accurate measurement.

product details

The thermal gas mass flowmeter has the following technical advantages:

ØA true mass flowmeter that does not require temperature and pressure compensation for gas flow measurement, making measurement convenient and accurate. The mass flow rate or standard volume flow rate of the gas can be obtained.


ØWide 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.


ØGood 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.


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


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


ØUsing RS-485 communication or HART communication can achieve factory automation and integration.
