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
- Compact size, easy installation, high reliability and high accuracy
- No need for temperature or pressure compensation
- Can be used for gas leak detection
- Good vibration resistance, no moving parts
- Available in Insertion and Flange Connection Type
- Clean gases
- Air
- Nitrogen
- Hydrogen
- Helium
- Ammonia
- Argon
- Other industrial gas
