Made of high-temperature resistant material, this product can be used with hot water up to 70 degrees Celsius. The pump can start when the water pressure reaches 0.03KG. Equipped with electronic components as the control device, it operates safely without generating sparks. This water flow switch features a water flow electromagnetic control system and on-off sensing elements for automatic pump control. The induction chamber, magnetic control chamber, and electronic components are separately designed to prevent switch failure caused by magnetic attraction of iron particles in the pipeline. Constructed with high-quality plastic and metal materials, this flow switch is durable and reliable. It measures approximately 7cm in length and 5.2cm in height. Suitable for low-pressure residential applications, it is especially important for low water pressure ignition in water heaters and automatic water circulation in solar water heating systems.
