Special features of TGF600 Thermal Mass Flowmeters

  • 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
  • Inline type can be installed/removed without stopping the line
  • No moving part, almost no pressure loss
  • Direct mass flow measurement, do not require temperature or pressure compensation

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.
