10 Best Water Tank Level Sensor 2026 in the United States

This wireless automatic water level control system uses an ultrasonic sensor to monitor water levels in pools, spas, and tanks, offering a convenient hands-off approach to maintaining water. It automatically refills the water when it drops below a set level, checking every 5 minutes to avoid waste. The system operates with three modes: automatic control based on water level, manual override to keep the valve open or closed, providing useful flexibility depending on your needs. It communicates wirelessly up to 500 feet, which is great for outdoor setups, and the controller is weather-resistant with an IP65 rating, making it durable for poolside or garden use.

The wall-mount sensor is powered by a corded electric source, so you don’t need to worry about batteries. The system also has indicator lights to alert you of valve status, low battery, or signal loss, helping you stay informed about your system’s operation. The system weighs nearly 4 pounds and is designed mainly for pools and similar water features, so it’s best suited for residential or small commercial use rather than large industrial tanks.
