Features: This water flow switch uses a magnetic water flow control device and on-off controls to turn the pump on or off. stable performance; induction chamber, magnetic control chamber and electronic components are designed separately to avoid switch failure caused by iron matter in the pipeline, which is magnetically adsorbed. High temperature resistant materials allow the product to be used for both hot (up to 70) and cold water. Starting at low water pressure; reset spring made of high quality stainless steel; can start the pump when the water pressure is> 0,03 KG. Electronic components as a control device do not cause sparks during operation, which is relatively safe. This product is widely used in the family of low pressure areas, especially important when starting the ignition of the water heater at low water pressure, automatic water circulation of the solar water heater. .
