Water flow switch JR-B678

Also named Pressure Control Flow Switch,Pressure Switch,Water Flow Sensor.It always works with water pump to control water pump state(work or stop) depends on its sensor for water flow or not.After open water equipment, the water will flow in water pipe, the flowing water impulse door sensors inside along the shaft to rotate the flow direction of water flow, magnetic device inside rotate with the shaft together, to a certain position, trigger the sensing element, the switch then is turned on, (if you connect it with the water pump),then the water pump starts to work. When the water is turned off, the pump then stop working.The switchs are widely used in the field of solar thermo system,water project,and industry field.

Materials: Plastic shell
Models: JR-B678, male connector 3/4″ to 3/4″;
