About the product

The Unitop Hydrostatic Fuel Tank Gauge from Afriso Euroindex is a pneumatic tank level indicator designed to display the quantity of fuel oil, diesel or AdBlue™ left in a storage tank. The Unitop is slightly more accurate than the similar Unitel version, and has a larger mechanical face. Like the Unitel, this tank level indicator has a spring loaded plunging mechanism that when released causes the needle to settle on the contents left within the storage tank, which is displayed in litres thanks to its calibrated nature. This fuel tank level gauge is compatible with both horizontal, vertical, cylindrical and rectangular tanks, with heights between 1200mm and 3000mm, making it suitable for a larger range of tanks than the other Unitop model.

The Unitop fuel tank gauge also has from a second adjustable needle for setting the level at which you want to identify that a fuel order is needed. Benefitting from an impact resistant outer case, this Euroindex contents gauge can easily be fitted to a wall or tank.

Upon ordering this gauge, please fill in the downloadable calibration questionnaire and send it to sales@centretank.com. Calibrated fuel tank gauges are made to customer specification, and there may therefore be a lead time of 5-10 working days.

How does this diesel and heating oil tank gauge work?

The hydrostatic fuel and heating oil tank gauge uses a submersible pressure sensor or balance chamber that is installed at a specific depth (zero level) into the tank. When the pressure sensor is filled with air by pumping a plunger on the gauge, it measures the pressure caused by the weight of the liquid directly on top of it, which allows you to get a reading.

Due to the hydrostatic paradox, the pressure sensor does not measure the complete volume in the tank above it, but only the liquid column vertically above it. For this reason, in order to provide a litre reading, these diesel and oil tank level gauges have to be calibrated with the tank shape and size details.

What’s the difference between calibrated and percentage fuel storage tank gauges?

A percentage fuel tank gauge is an off the shelf product that can be fitted to a tank to provide a reading of the contents as a percentage. A calibrated fuel tank gauge on the other hand is manufactured to meet the exact dimensions and shape of the tank, allowing the level reading to be provided in litres.

Calibrated fuel tank level gauges can be more useful for the tank owner as if they know their approximate usage, a litre reading can help them work out how soon they will need a fuel delivery.

Why do I have to fill out a questionnaire?

If you are buying a calibrated fuel tank contents gauge then you will always need to fill out a tank questionnaire which requests details such as the exact dimensions and shape of the tank, as well as the fluid the tank contains. As a calibrated tank level gauge’s reading is in litres, if any of the information needed about the tank is wrong or missing, then an inaccurate reading will be given.
