Corrosion Resistant Plastic Hall Sensor Water Flow Sensor Switch Energy Efficient Water Heater Parts

Overview
This G1/2 brass water flow sensor is a universal replacement part for various water heating equipment. It adopts high-precision rotor induction technology to detect real-time water flow and output pulse signal to the control panel. When water flows through the sensor, it will activate the heating circuit; once water stops, the sensor cuts off heating power instantly to prevent dry burning damage to heaters. Equipped with anti-corrosion brass thread and high-temperature resistant plastic shell, it works stably in hot water circulation systems for a long time. Widely compatible with gas water heaters, instant electric water heaters, solar water heaters, boilers, water pumps and water dispensers.

Key Advantages
Premium Brass Inlet & Outlet
The thickened copper thread has excellent anti-rust and sealing performance, effectively avoid water leakage caused by long-term hot water erosion.

Reliable Dry Burning Protection
High-sensitivity flow sensing design, small water flow can trigger signal, automatically stop heating without water to protect heating elements.

Wide Temperature & Voltage Adaptation
Support water temperature up to 100℃, DC 3-24V wide voltage input, perfectly match most household heating equipment control systems.

Plug & Play Wiring Design
3-color coded wire with plastic terminal plug, directly insert into the mainboard socket without complicated soldering, greatly reduce installation difficulty.

Easy Installation & Replacement
Standard G1/2 external thread, directly screw into the original pipeline, ideal aftermarket spare part for broken old flow sensors.

Installation Tips
Install the sensor according to the marked water flow direction on the body, do not reverse the water inlet and outlet.

Wrap raw tape around the brass thread before installation to enhance sealing and prevent water leakage.

Check the wire terminal plug tightly connected to the control board to avoid loose contact.

This sensor is only suitable for clean tap water circulation, do not use in water with large particles of impurities.
