Watchman SENSIT Domestic Oil or water tank monitor/gauge
The Kingspan SENSiT is a smart Wi-Fi tank level monitor that enables you to monitor and control your oil levels through the smartphone app. You can check your tank's 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!
IMPORTANT
This product has been designed to work with domestic Wi-Fi 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

Will this product prevent runouts or overfills?
This product is designed to assist with monitoring and managing tank levels by providing indicative level data. It does not actively prevent run-outs or overfills. The accuracy of the reported data is approximately ±5%, depending entirely on the accuracy and completeness of the setup information and parameters provided by the customer.
It remains the customer’s full responsibility to ensure that correct configuration details are supplied and that data is reviewed regularly. The manufacturer and supplier accept no liability for run-outs or overfills if data is not sent, received, or displayed due to network issues, server downtime, customer internet failures, or other transmission disruptions. This product supports level management but is not a fail-safe device or guaranteed prevention system.

Please ensure the product you are ordering is the correct size and suitable for the purpose. Special order, bespoke and non-stock tanks are not returnable. If you order a tank and find it is too big, too small, or unsuitable for your requirements, it can be expensive to return. Our cancellation & returns policy explains this in more detail — see Terms & Conditions.

Overseas orders

A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
