ABSTRACT:
The invention relates to a method and device for determining the quantity of fluid discharged from a tank via a line system. To this end, the difference between the quantity of fluid contained inside the tank before fluid discharge and the quantity of fluid remaining inside the tank after fluid is discharged is calculated. In addition, a measuring device measures the quantity of fluid, which is contained inside the line system and which is taken into consideration when determining the discharged quantity of fluid.
