RF3700 Thermal Gas Mass Flowmeter

Thermal mass flow meters, also known as thermal dispersion or immersible mass flow meters comprise a family of instruments for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits. Thermal gas mass flow meter is designed on the basis of thermal dispersion, and adopts method of constant differential temperature to measure gas flow. It has advantages of small size, easy installation, high reliability and high accuracy, etc
