Apollo XT Electronic Fuel Tank Contents Gauge (Underground Tank) Description

Apollo XT Electronic Fuel Tank Contents Gauge (Underground Tank)

The Apollo XT Electronic Fuel Tank Contents Gauge allows you to measure the level of fuel in your tank from the warmth, comfort and convenience of your home. It also allows the tank contents readings to be taken at the tank. Designed for use with oil tanks installed underground or positioned above safe working height (not Balmoral underground tanks).

NB: Delivery approx 7 working days (Royal Mail Recorded Delivery)

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 multipart 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 the level of fuel remaining inside the tank.


  • Compatible with the standard 32mm port fitted to modern plastic oil storage tanks (please ensure adequate space on tank to mount transmitter)
  • Optional multi adaptor ensures compatibility with most steel tanks.

Apollo XT Electronic Fuel Tank Contents Gauge (Underground 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.


Tanks Over 2500L – Articulated Lorry – Customer Offload:

These tanks will be delivered on an articulated vehicle (approximately 16.5m long x 2.6m wide x 3m high) which has no offloading on board, it is the customer's responsibility to offload the tank, which may require a telehandler / forklift.  Curtain sided vehicles are also used, so please note that if there are obstacles or hanging branches on the road to the delivery site etc, the driver may refuse to drive the vehicle to the customer's location due to the possibility of damaging the vehicle. Please let us know if there are any obstructions before delivery, so we can arrange alternative transport.


18 Tonne Tail Lift HGV

This vehicle is the size of the largest bin lorries (for comparison) and is approximately 8.2m long x 2.6m wide x 4m high, often curtain sided so please note that if there are hanging branches etc, these vehicles will not attempt to drive down due to the possibility of damaging the vehicle and so it is recommended that a smaller vehicle is requested. Tanks will be lowered to the ground but not positioned as this is a kerbside delivery.  If a smaller vehicle is required, please email us at sales@fueltankshop.co.uk quoting your order number and name.


HIAB Delivery

HIAB delivery is available but must be requested and there will be an additional cost for this service. If a HIAB delivery is required, please email us at sales@fueltankshop.co.uk quoting your order number and name, and we will come back to you with a price for this service.



Most accessories will be delivered within 1-3 working days (certain products and postcodes may take longer, please check the product page for update to date information). If you require them quicker, we can on occasions offer a next day service (please contact us to discuss).
