Product Description


Compress Air Thermal Mass Gas Flow Meter Hydrogen Oxygen Measure Gas Flowmeter China Manufacturer
Thermal Type Gas Mass Flowmeter utilizes the principle of heat exchange to measure fluid -flow. This meter employs 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 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 measurement can be made under high temperature and high pressure situation.
