TGF450 thermal mass flow meters

TGF450 thermal mass flow meters is a measurement solution specially designed for compressed air, nitrogen gas, oxygen. It can provide a stable and accurate measurement at a more economical cost. It has 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
  • Designed for  air and nitrogen flow measurements, especially for compressed air
  • Standard output is pulse and RS485, Hart@4~20mA and 4~20mA is available
