advantage of differential pressure switches in flow detecting system

The differential pressure type flow switch can effectively protect the water flow caused by the filter blockage from the flow protection value. If the two-way valve is used for the coil unit at the end of the installation unit, i.e. the variable water system is used incorrectly, when the number of two-way valves is gradually closed, once the flow of the two-way valve being opened is less than the off flow of the differential pressure switch, the differential pressure switch will accurately output the off signal within 3 seconds.
