The RATNOTECH Fully Automatic Water Level Controller is a smart and energy-efficient solution designed to automatically manage water levels in overhead tanks. This advanced controller ensures seamless pump operation, preventing water wastage and motor damage. It switches ON the pump when the tank level drops below 50% and turns it OFF when full or in case of voltage fluctuations. The device is compatible with motors up to 3 HP and works with normal ON/OFF switches, MCBs, and electronic starters (if bypassed). Equipped with intelligent voltage protection, it automatically shuts off during high or low voltage, safeguarding your pump. The dry run protection feature stops operation if the pump is running without water, extending motor life. Pulse sensing technology ensures long sensor life and precise water level detection. The system also includes LED indicators for motor status, tank levels, power supply, overvoltage, undervoltage, dry run, and water flow. With dual operation modes, users can select AUTO mode for fully automatic water level management or MANUAL mode to keep the pump running continuously.
