Beschreibung
Zusammenfassung:	The system (1) has a flow meter (6) provided in a filler neck (4) of a fuel tank (2). The flow meter is coupled with a level control valve (13) in a controllable manner to calibrate the system. The level control valve comprises a circuitry mechanism by which a signal of the level control valve is time-delayed and passed to a control device. The flow meter has no or very less flow resistance. A vent line (16) is closed when the level control valve determines that a maximum level (3) of fuel is reached in the fuel tank. An independent claim is also included for a method for determining a level of fuel in a fuel tank. Die Erfindung betrifft ein System zum Ermitteln eines Füllstands (3) von Kraftstoff in einem Kraftstoffbehälter (2), mit einem Durchflussmesser (6) in einem Einfüllstutzen (4) des Kraftstoffbehälters (2). Um die Ermittlung des Füllstands von Kraftstoff in einem Kraftstoffbehälter weiter zu vereinfachen beziehungsweise zu verbessern, ist der Durchflussmesser (6) steuerungsmäßig mit einem Füllstandbegrenzungsventil (13) gekoppelt, um das System (1) zu kalibrieren.
