Flow / Air Velocity / Flow Transmitter / Air Volume


Thermal Mass Flow Transmitter

Different probes flexible use for slightly corrosive or pure air
Strong housing with analog and RS-485 output

Resistance temperature detector (RTD)
Analog and RS-485 output
IP67, strong stainless steel housing
Applicable slightly corrosive or pure air
Built-in with temperature compensation, accommodate quickly any environment

FTM06 is based on thermodynamic principle,  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.
