Thermal Gas Mass Flow meter

Thermal Gas Mass Flow meter

Product Details:


Product Description


  • Measuring the mass flow or volume flow of gas 
  •  Do not need to do temperature and pressure compensation in principle with accurate measurement and easy operation. 
  • Wide range: 0.5Nm~100Nm/s for gas. The meter also can be used for gas leak detection 
  • Good vibration resistance and long service life. No moving parts and pressure sensor in transducer, no vibration influence on the measurement accuracy. 
  •  Easy installation and maintenance. If the conditions on site are permissible, the meter can achieve a hot-tapped installation and maintenance. (Special order of custom-made) 
  • Digital design, high accuracy and stability 
  •  Configuring with RS485 or HART interface to realize factory automation and integration


  • Measuring Medium: Various gases (Except the acetylene)
  • Pipe Size: DN10~DN4000mm
  • Velocity: 0.1~100 Nm/
