Trading in the petrochemical industry makes use of tanks as measuring equipment. The volume of the tank determines the quantity of fuel in it. However, reliance on the nominal volume of a tank mostly results in an error of about 1% or more (shortage mostly) and this translates into losses of huge sums of money over time. Every drop counts.
In order to reduce this error, there is the need to know more precisely the volume of the tank used and this is done through calibration. Calibration is a set of operations done to establish under specific conditions, the level and volume of fuel in the tank.
