TankMate LTE sensors connect to the low power, wide-area NB-IoT network in New Zealand. If your tank has cell phone coverage, it will most likely have access to Spark's dedicated NB-IoT network. Use this map, then filter for NB-IoT to check coverage in your location.
The R3 LTE sensor provides accurate and affordable tank level monitoring:
- Fully sealed sensor unit utilises a non-contact radar sensor to measure tank levels with millimetre accuracy, ensuring years of trouble-free operation.
- Housed in a robust polycarbonate enclosure with an IP68 weatherproof rating to withstand the elements.
- Powered by 3x AA Energiser Ultimate Lithium batteries, the sensor requires no external power and provides intelligent battery monitoring via the mobile app.
- Compatible with a wide range of tank types and shapes.
- Easy installation requires a 30mm hole to be drilled in the tank lid or 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.
- Access your tank data online with the TankMate app for mobile (iOS & Android).
