Water Flow Sensor for Fire Fighting System

Water Flow Sensor for fire fighting systemIntroductionWater 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.Technical parametersConnection TypeSaddle TypeModelZSJZ/ANominal Diameter(mm)50/65/80/100/125/150/200/250Working Pressure(Mpa)1.2 (12bar)Delay Time(s)2-90Sensitivity(L/Min)15~37.5Contact CapacityAC220V,5A/DC24V,3A  Connection TypeFlange TypeModelZSJZ/FNominal Diameter(mm)50/65/80/100/125/150/200/250Working Pressure(Mpa)1.2Delay Time(s)2-90Sensitivity(L/Min)15~37.5Contact CapacityAC220V,5A/DC24V,3A  Connection TypeThread TypeModelZSJZ/SNominal Diameter(mm)50~150Working Pressure(Mpa)1.2Delay Time(s)2-90Sensitivity(L/Min)15~37.5Contact CapacityAC220V,5A/DC24V,3A  Connection TypeWelding TypeModelZSJZ/HNominal Diameter(mm)50/65/80/100/125/150/200/250Working Pressure(Mpa)1.2Delay Time(s)2-90Sensitivity(L/Min)15~37.5Contact CapacityAC220V,5A/DC24V,3APhotoes Other Firefighting Equipment   /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
