Principle Introduction:
Winsen Electronics produces F1022 micro flow sensor, adopting thermodynamic principle to detect the gas flow.
F1022 micro flow sensor adopts thermodynamic principle to detect the gas flow, and it has high accuracy and good repeatability. The built-in temperature sensor makes the product has the function of professional temperature compensation calibration. At the same time, the output is linear analog voltage which is convenient to use.

Applications :
Industrial process control
Air and environment protection
