FTM06D is based on thermodynamic principles 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.
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.
