Water Flow Switch Adjustable Control G3/4 G1/2 220V Automatic Thread Sensor

【PREMIUM MATERIAL】High temperature resistant materials allows the water flow switch to be used for both hot(up to 70) and cold water. 【PRESSURE STARTUP】The flow sensor switch with low water pressure startup. Reset spring is made of high quality stainless steel, which can start up pump when water pressure is >0.03KG. 【WIDE APPLICATIONS】The automatic flow switch is widely used for low pressure area family, especially for low water pressure ignition start-up of water heater, and automatic water cycle of solar water heater. 【STABLE PERFORMANCE】The induction chamber, magnetic control chamber and electronic components are designed separately in order to avoid switch failure caused by iron matter in pipeline is magnetic adsorbed. 【SECURITY GUARANTEED】The electronic components as control device will not cause spark during work which is quite safe.
