Flowma TGF06C-A Thermal Mass Flowmeter


Flowma TGF06C-A Thermal Mass Flowmeter

Flowma TGF06C-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 a fter processed that is why flow rate can be measured by these two sensors. All-metal housing, suitable for a variety of pipe diameters.
