The working principle of the water flow switch is about to open the water, the pressure switch is about to reach a certain pressure on the pressure off. Take the water pipe to the ratio. Water pipe leaks a drop of water flow switch it is open, and the pressure switch it leaks up to a certain pressure it does not open, that good?
if it is used for pumping or pressurized water injection of these, then the pressure switch must be,
Friends, if you are used for water pipes to prevent water waste, then it is certainly better flow switch,
that is, like a washing machine as pressure switch control The motor is turned on and stopped.
