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.
