Hydro-Air Flow Swift PFM500 Series

PFM500
Thermal flow switch.
Hydro-Air PFM500 Thermal Flow Switch adopts the principle of thermal diffusion. The temperature difference between the two sensors can be used as the basis for measuring the flow rate.
When the flow rate of the medium increases, the temperature difference decreases and vice versa.
