Product Description

Water Flow Switch For Fire Fighting System

Introduction
Water flow indicator is uesed in automatic water spray extinguishing system.they can be installed in main water supply pipe or brand pipe.then they deliver flow signals of one area,Signals can reach electric contronal box and also can be used for starting fire water pump control switch.
We makes all kinds of water flow indicator. There are with time circuit ZSJZ(A model) or without time delayer circuit ZSJZ(B model) ,are of seven specifications such as 50(2") 65(2-1/2") 80(3") 100(4") 125(5") 150(6") 200(8") to serve different pipes, connecting ways: pipe threaded, welding type,flanged type and saddle type for users' choice.
