How it works
Apollo Ultrasonic is the original ultrasonic oil tank contents gauge and comprises a tank mounted transmitter unit and a plug in receiver unit. The transmitter monitors the level of fuel inside the tank and relays this data via a secure, wireless connection to the receiver unit, which cleverly and conveniently plugs into a standard electrical socket. The receiver unit displays the level of fuel inside the tank, via an easy to read LCD display, which usefully includes a low level warning alert.

Apollo Ultrasonic is suitable for almost any tank up to 3 metres tall and is available with either a 3 pin UK/Ireland or 2 pin European electrical (extra cost) socket connection. Easy to fit, the Apollo Ultrasonic can be installed in minutes.

Product Features:

  • Tank mounted ultrasonic transmitter unit, compatible with the standard 20mm port fitted to modern plastic oil storage tanks.
  • Optional multi adaptor ensures compatibility with most steel tanks and larger holes.
  • Plug in receiver unit with integral antenna
  • Premium quality LCD display, readable from a wide range of angles under varying light conditions


  • One size fits all. The Apollo Ultrasonic is suitable for almost any tank up to 3 metres tall, irrespective of manufacturer, capacity or material of construction.
  • Quick and easy to fit, with no specialist tools or wiring required
  • Easy to use, thanks to an intuitive, easy to read LCD display
  • On-screen, low level warning alert with audible alarm, reduces the risk of running out of oil
  • Contactless technology and the absence of a direct connection to the oil supply line eliminates the risk of spills and leaks.
  • Adds value to oil storage tanks and fuel storage installations.
  • Positioned above the maximum liquid level inside the tank, the Apollo Ultrasonic can assist in ensuring compliance with secondary containment requirements.

Ideal for monitoring heating oil and diesel – but suitable too for a wide range of liquids including admixtures, agricultural fuel oil, anti-freeze, biodiesel, bio heating oil, fuel oil, detergents, lubricants, waste oil and water.

Up to 200 metres line of sight range via secure, wireless, FM data transmissions.

Fully compliant with all applicable environmental and technical requirements.

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.
