The thermal gas mass flow meter utilizes the principle of heat exchange to measure fluid flow. This thermal mass meter employs a method of constant temperature difference to accurately measure gas mass flow, and it has the advantages of small size, high degree of digitization, easy installation, accurate measurement, etc.

The sensor part of thermal mass flow meter consists of two platinum resistance converters of reference level. It utilizes bridge type loop circuit, with one converter measuring fluid temperature, and another maintaining constant temperature difference that is higher than fluid temperature. The thermal mass meter measurement can be made under high temperature and high pressure situation. 

It is a true thermal mass flow meter that can conveniently and accurately measure gas-flow rate without temperature and pressure compensation, from which users can get gas mass flow or standard volume flow.

Large ratio of measuring range. our thermal gas mass flow meter can measure gas with velocity of flow from 100Nm/s to 0.5Nm/s, and be used in gas leak hunting. Factory automation and integration can be achieved by using RS-485 or HART communication.
