Thermal Mass Air Flow Meter Protection class IP67 has a robust stainless steel case and is suitable for various demanding processes. It is highly sensıtıve but its easy to install. It has a built-in sensing element and long-term stability.
It is possible to choose between multifunctional physical quantities (Air speed and volume): [m / s], [ft / s] [ Nm 3 / h] [Nm / s] [L / min] [m3 / min]
In the thermal air flow meter, air speed and temperature can be monitored simultaneously on the LCD Screen.
FTM 94 / 95 is a thermal air velocity transmitter operating at a constant temperature. Using King's law heat balance equation;
e2 = a '+ b'v n
e : Sensor voltage output (V)
a':Zero output of Thermal anemometer at constant temperature, can use CTA circuit as temperature compensation
b': Sensitivity of the sensor regarding operating temperature
v:Liquid flow rate
n: 0.45 ... 0.5 (Standard)
can be calculated from the formula characteristic curve of constant temperature. Thermal anemometer has a special double PT probe and full metal body design. With high accuracy, it is suitable for various pipe diameters and is widely used in industrial areas.
