Abstract: The invention relates to a method and to a device for determining an amount of gaseous fuel, which during a refueling process at a gas station has been transferred into a storage tank via a gas pump (3) and a filling hose (4) connected thereto, wherein in the gas pump (3) of the gas station, a flow meter (F) is provided, which during the filling of the storage tank detects the amount of fuel dispensed. Once the filling is completed, the filling hose (4) is depressurized, and the amount of fuel, which has not been transferred into the storage tank due to the depressurization, is detected, and this amount is subtracted from the amount detected by the flow meter (F).
