TGF450 Thermal mass flow meter

TGF450 thermal mass flow meter is a measurement solution specially designed for compressed air, nitrogen gas, oxygen.

Provide a stable and accurate measurement at a more economical cost. and 1.5% FS+0.5RD accuracy on a 100:1 wide turndown ratio. The compact design and thick probe are easier to be installed on high pressure pipeline with limited room.

Advantages at a glance:

  • Minimum flow rate down to 0.3m/s, 1:100 super-wide turndown ratio
  • Compressed air, Nitrogen, non-corresive flow measurement
  • pulse and RS485 as a standard, Hart@4~20mA for option
  • Hot tapping install, support isntall under pressure
  • Bluetooth app offer very easy friendly operating interface
