Calibration of Storage Tanks

Storage tanks are often used as measuring instrument, especially when it comes to petroleum products. If the nominal area (from the design drawing) is used to calculate the volume, most likely you end up some percentage off. To narrow that down, for the obvious reason that some percentage is a lot of money, one needs to know the effective area better. By calibrating the tank, it is possible to create a really good measuring device. In many countries it is legally mandatory to calibrate tanks that are used for custody transfer in any form or for inventory taxes.

We have been calibrating storage tanks of all shapes and sizes since 1937. We are able to carry out the measurements to meet different level of uncertainty, depending what has to be met with the particular tank. We operate mainly in northern Europe, but can quickly set up teams for assignments at other locations.

The tank is better calibrated when empty. In many cases it is not even possible to carry out the measurements other than by entering the tank. Tanks that are too small or not accessible for geometric measurement are calibrated using volumetric methods.

Along with a traditional certificate revealing the tank as a measuring device, we often derive other type of information giving information about installations and floating roofs.
