The Apollo XT Remote fuel oil tank contents gauge, is designed for use with oil tanks installed underground or positioned above safe working height. Such tanks are notoriously difficult to refuel safely. Apollo XT assists in achieving compliance with Health & Safety requirements by allowing the level of fuel remaining inside such tanks to be quickly, safely and accurately determined.

How it works
Apollo XT is a multi-part system, comprising a tank mounted ultrasonic measurement sensor; a remote, wireless transmitter unit; and a plug in receiver unit.

The on-tank measurement sensor monitors the level of fuel inside the tank and relays this information via a hardwired connection, to the transmitter unit which is positioned adjacent to the fill point. The transmitter unit features an inbuilt LCD display, showing the level of fuel inside the tank before, during and after refuelling.

The transmitter unit wirelessly relays tank level data to the receiver unit, which simply plugs into a stand 13 amp domestic socket. The receiver unit incorporates a premium quality LCD display, which allows users to easily ascertain level of fuel remaining inside the tank.

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.
