Feature The mechanical part is isolated from the electronic part. The product does not contain bellows that can easily cause failures. The liquid contact materials are all reinforced nylon or PPO. PVC outer wire joints can be selected, and all UPVC tee fittings are compatible. It is suitable for UPVC pipes currently used in seawater or swimming pool heat pumps. Uses an imported magnetic switch as the electrical actuating component. It has a low disconnection and reset flow rate, with negligible pressure drop, making it ideal for swimming pool heat pumps and other heat pump systems. Adjustable flow protection capability. Application Gas-liquid dual-purpose type, widely used in industrial automation, mechanical equipment, air compression industry, refrigeration, and air conditioning fields. The water flow switch magnet is not located in the water flow path, allowing use in sewage systems where it can operate reliably.
