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. After processing, the temperature difference value is converted into standard electrical signal output and displayed.
It uses the all-metal shell design, 6-bit LED display flow trend and switch state. Its potentiometer is simple to set up and easy to operate, without any internal moving parts, maintenance-free, can measure a variety of media.
It is widely used in water and electricity, tap water, chemical, machinery, hydraulic and other industries.
