Flowma TGF06D-A Air Thermal Mass Flow Meter

Flowma TGF06D-A is based on the thermodynamic principle and can measure air velocity and air volume, There are 2 temperature sensors inside the probe one for temperature measurement, and the other one as a measuring conveyor after heating.

Flowma TGF06D-A Features

  • Flowma TGF06D-A Temperature difference between the two as a basis for measuring flow rate. When the medium flow rate increases, the temperature difference decreases.
  • The temperature difference is converted to standard signal output after processing which is why the flow rate can be measured by these two sensors. All-metal housing, suitable for a variety of pipe diameters.


  • Thermal mass flow sensor
  • Can measure air velocity and air volume
  • Analog / RS-485 / Impulse output
  • Built-in temperature compensation, accurate measurement
  • Using constant temperature anemometer(CTA) technology, good sensitivity
  • Unit setting:[m/s], [ft/s], [Nm 3 /h], [L/min], [°C], [°F]
  • Strong stainless steel housing, for a variety of harsh environments
