About the product
The Unitel Hydrostatic Fuel Tank Gauge from Afriso Euroindex is a pneumatic tank level indicator designed for use primarily on fuel oil and diesel tanks, but also used as an AdBlue tank gauge. It has a spring loaded plunger that you pull and release until the needle settles on the contents left within the storage tank, which is then displayed clearly as a percentage on its large mechanical face. This fuel tank level gauge is suitable for horizontal, vertical, cylindrical and rectangular tanks, with heights between 1200mm and 3000mm for diesel and up to 2500mm for water/AdBlue , making the Unitel a highly popular and versatile tank level indicator.
The Unitel fuel tank gauge also benefits from a handy adjustable second needle for setting a level parameter, which you can then use to indicate the level at which you need to reorder fuel. Supplied in an impact resistant casing, the Euroindex contents gauge can be easily wall or tank mounted.
Please note: If being used with HVO, the gauge should be re-calibrated as per the matrix in the instruction manual based on it's SG of 0.78 (diesel is 0.84).

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.
