Water Flow Switch Sensor 0.75-0.75 inch Automatic Pump Controller Inline Water Pump Pressure Switch Control 200-300W

The Water Flow Switch Sensor is an automatic inline pump controller designed to manage water pumps based on real-time flow detection. When water starts flowing through the pipeline, the switch activates the pump, and when the flow stops, it automatically shuts the pump off. This protects the pump from dry running and improves system efficiency.

Manufactured with high-temperature-resistant and anti-corrosive materials, the unit is suitable for both hot and cold water systems. Its isolated magnetic control chamber prevents interference from iron debris, ensuring stable and spark-free operation. The flow switch is ideal for residential water booster systems and various industrial applications.
