Product Description
DN 65 Factory price flue gas mass air flow meter with totalizer

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, the high degree of digitization, easy installation, accurate measurement, etc.

The sensor part consists of two platinum resistance converters of the reference level. It utilizes the 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.Technical Parameters Of Thermal Gas Mass Flow Meter
