ANW211FS Electronic Liquid Flow Switch

The flow switch is based on the thermal principle, and there are two resistances in the sealed probe, one of which is heated as the probe resistance and the other is not heated as the base resistance.

When the medium flows, the amount of heat on the heating resistor is taken away, and the resistance value is changed.Two electrical resistance difference values are used as the basis for judging the flow speed, and there are no moving parts, so it is free of maintenance and convenient to install, and one type is suitable for multiple pipe diameters.
