In underground storage tank (UST) systems, there are three areas where fuel can be lost: sales, deliveries or a leak in the tank and lines. In order to lose fuel through sales, the dispenser pumps more fuel than the meters register.
The only way to lose fuel through deliveries is a discrepancy in the number of litres reported delivered and the number of litres actually received. If the integrity of the tank or line is compromised, then fuel can be lost as a result.
The most common area where fuel losses are identified is in the sales process with the miscalibration of meters.While individual meter miscalibrations may appear to be small and insignificant, the aggregate of these miscalibrations results in the loss of significant profits.
