Our most advanced sensor to date, the R3 sensor provides accurate and affordable tank level monitoring. The fully sealed sensor unit uses a non-contact radar sensor to measure tank levels with millimeter accuracy, to ensure years of trouble free operation.
Our R3 sensors are housed inside a robust polycarbonate enclosure with an IP68 weatherproof rating to ensure it can stand up to the elements. Powered by 3 x AA Lithium batteries, the sensor requires no external power and provides intelligent battery monitoring via the mobile app.

Key Features
This sensor can be used with a variety of tank types and shapes - installation requires a 30mm hole to be drilled in the tank lid / roof (at least 100mm above the water height). A single sensor can be used to monitor multiple tanks that are connected and have a common level.
