This, however, does not affect the accuracy of the volume measurements, as the fuel delivered to a given storage tank is tracked based upon when a zero flow is sensed in relation when the identifier for that storage tank 26a - 26c is captured. If accurate information is desired concerning the specific storage tank into which the fuel is transferred, the passive ID device 30 corresponding to that storage tank must be read before the initial zero flow indication for fuel being transferred to that storage tank.

Rather than incurring a delay in identifying units before commencing the pumping of fuel into those units, which can add up to a considerable delay within a given shift, the operator can simply put the hose nozzle 50 into the fueling spigot of the appropriate storage tank first, and while fuel is being transferred to the storage tank, capture the unit information with the use of wand 100.

Abstract

L'invention concerne un appareil, un procédé et un système facilitant la livraison de carburant par un camion-citerne sur le site du client. Une lance (100) manuelle autonome permet aux opérateurs de livraison du camion de carburant de recueillir automatiquement les informations d'identificateurs d'unités à partir d'un dispositif mémoire (20) situé à proximité d'une cuve de stockage (26a) donnée, le dispositif mémoire étant associé à cette dernière. Cette lance manuelle permet également à l'opérateur d'inscrire des informations d'identificateurs d'unités dans de nouveaux dispositifs mémoires sur place, sans que l'opérateur ait besoin d'entrer manuellement ces informations d'identificateurs d'unités dans une mémoire locale située à l'intérieur de la lance manuelle lorsqu'il n'y a pas de dispositifs mémoires sur le site du client. Les informations recueillies sont téléchargées sur un ordinateur à bord du camion de livraison, de sorte à établir une corrélation, à la fin du ravitaillement, entre les périodes début/fin d'écoulement réelles enregistrées par l'ordinateur à bord (12). Un ticket/reçu est ensuite imprimé pour le client.
