FTM94/95 Hot wire thermal air velocity transmitter working at a constant Temp. using King's law heat balance equation for:

e2=a'+b'vn
e Sensor voltage output(V)
a':
Zero output of constant temperature hot wire anemometer, can be eliminated by circuit
b': Sensitivity of the sensor, related to the operating temperature
v: Fluid flow rate
n: 0.45 ... 0.5(Standard)
     
Can be calculated from the formula characteristic curve of constant Temp. hot wire anemometer, special double PT probe and full metal housing design, high accuracy, suitable for a variety of pipe diameters, widely used in industrial fields.
