Abstract: A quantity of gas is introduced into a gas reservoir via a filling station provided with a filling line. The quantity is measured. A signal is generated indicating a corrected quantity of transferred gas. The signal is obtained by adding a predetermined, positive or negative, corrective amount to the measured quantity of gas transferred.
