Flow / Air Velocity / Flow Transmitter / Air Volume


Thermal Mass Gas Flow Meter Controller【Preliminary】

FTM09 Thermal Gas Mass Flow converter is designed on the basis of thermal dispersion,and adopts the method of constant differential temperature to measuring gas flow. It has advantages of small size, easy installation, high reliability and high accuracy, etc. Excellent nonlinearity correction function, greatly improve the appearance of linearity. Improve the ability of anti-interference and vibration resistance. Strong versatility, can be matched with the vortex sensor, vortex precession, turbine output frequency signal using, the rich self-checking information makes easy maintenance and debugging.
