Product Description

The Kingspan SENSiT is a smart WiFi tank level monitor that enables you to monitor and control your oil levels through the smartphone app. You can check your tanks level from anywhere and you will get notifications and alerts to your smart device when there are sudden drops in oil, predicted run out, consumption monitoring and low level alerts. The SENSiT even works with Alexa, so when asked 'How much oil is in my Tank?', she will be able to let you know!


This product has been designed to work with domestic WiFi routers. In the case of mobile broadband and business routers or managed networks please check with your provider or network administrator before purchasing this device

Level in the APP is updated once per day in the early morning hours and it's rounded to the nearest 5%. Environmental factors e.g. temperature and registered tank details may affect the accuracy

How it works

Returns Information

Customers may return items within 14 calendar days (as per our Terms & Conditions) - refer to 4.6 & 4.7. **

Please be aware that returning a tank can be complicated and expensive so please check that you are ordering the correct item (we suggest checking the dimensions very carefully).

Delivery Information


The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page.  Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.


Most accessories will be delivered within 1-3 working days. If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock we will advise you of the expected lead time and you will of course have the opportunity to cancel with a full refund.

"Brilliant device, no more wondering what the oil levels are like. I fitted it to replace an existing gauge and through a process of guess work was able to use the adapter with the existing thread on the steel oil tank. It could be made more clear that this was possible. But otherwise no problems!"
