Hunter RAINCLIK Wired Rain Sensor

The Hunter Flow-Clik™ is a dependable flow shut-off sensor designed to protect irrigation systems from damage caused by pipe breaks, stuck valves, or uncontrolled high-flow conditions. By continuously monitoring water flow, the Flow-Clik automatically interrupts power from the irrigation controller to the valves when flow exceeds a user-defined threshold, helping prevent flooding, erosion, and costly water loss.

The system features a two-piece design, consisting of an inline PVC flow sensor and a programmable interface panel mounted near the irrigation controller. A magnetic impeller inside the sensor detects water movement with high accuracy, while fully sealed, waterproof electronics ensure long-term reliability in harsh outdoor environments. The interface panel provides simple calibration, adjustable response settings, and clear LED feedback so installers and users can quickly confirm system status.

Compatible with all Hunter AC-powered irrigation controllers, the Flow-Clik is an ideal safety device for residential, commercial, and agricultural irrigation systems where flow protection is essential.
