TGF600 Inline Thermal Gas Flowmeters

TGF600 Inline Thermal Gas Flowmeters with more rugged design to adapt to harsh industrial applications. It implements COMATE’s latest sensor filming technology and high sensitivity sensors to ensure a stable measurement at very low flow rate down to 0.3Nm/s.

Special features:

  • 100:1 turndown, lower limit to 0.3Nm/s support from 1”~80”pipe
  • Temperature range up to 450 °C
  • Depth scale for precise installation
  • Insertion type to 16bar, special version up to 63 bar
  • No moving parts, industrial sensor more robust and easy to clean
  • Unique anti-ejection densign support install and remove without stop the line
  • IP 67 protection.Robust water-proof housing for the indoor/outdoor area


  • Compressed air, Natural gas, biogas, Oxygen, Argon, Hydrogen, special area
  • Coal, power, Incineration, Landfill gas, Petrochemical industry and gas measurement in Heating supply system
  • Flare gas, etc high temperature gas measurement

TGF600 Series inline thermal gas flowmeters measures the gas mass flow base on thermal dispersion theory. It combines COMATE’s advanced technology on transmitter, sensor, filming and calibration, can provide stable and accurate measurement even under harsh industrial applications and require very less maintaining.

  • Insertion Type

The insertion type thermal mass flowmeters can be installed and maintained online.

  • In-line Type

The in-line type thermal mass flow meters is delivered along with a pipe which has a same inner diameters as the pipe in field.

The flanges meet ANSI,DIN or JIS standard.
