The next generation of TankMate sensors has arrived!

Our most advanced sensor to date, the R3 sensor builds on the success of the V2 model to provide 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 3xAA batteries, the sensor requires no external power and provides intelligent battery monitoring via the mobile app. 

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. 

Access your tank data online with the free TankMate app for mobile (iOS & Android) and web. 

Optional in-app Premium features include phone notifications, detailed usage statistics, and multiple sensor monitoring (12 month free trial period included with first purchase). See app page for pricing.

Note: WiFi connected product - ensure your tank has network coverage. iOS or Android mobile app required for initial set up.

Tankmate Review

Sensor works fine, a little more information on the app would be helpful,

Ron Stevens
Great sensor

I am very happy with the sensor. I had to put in quite a lot of work to get wifi to the tanks, and it took a while for the unit to settle down and give regular readings, but working well now. With the long hot dry summer predicted I am sure the sensor will help us manage our water usage. Much more easier than using a dipstick!!

Dominic Cameron
Great Gadget!

Looking around the different options that were available I decided to buy the R3 and I have to say it is great! Install and set up was fairly straightforward and the readings seem accurate. App tells you what you need to know, you have the option to drill down into your usage further if you want. For the money I’m very happy!


Great product but the app would not install on my Samsung S22
