Flowma TGF06D-A Air Thermal Mass Flow Meter

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

Description

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

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 converted to standard signal output after processed that is why flow rate can be measured by these two sensors. All-metal housing, suitable for a variety of pipe diameters.
