The RF water level sensor mounts to the top of your tank and uses ultrasonic pulses to measure the distance to the water surface. This reading is sent wirelessly to the RF-WiFi gateway, which relays the data to your smartphone app. The app then calculates and displays your tank’s water percentage in real time, with customizable high and low alarms to keep you informed.

DIY-friendly setup in minutes. The built-in level indicator helps you align the sensor on the tank lid and pair with the RF–WiFi gateway quickly.
