A delivery vehicle is used to deliver oil with or without a marker and is provided with apparatus which includes a reservoir (7) of marker and an injector pump (10) for adding marker to the oil. A controller (13) records the occurrence of an event associated with the depletion of the reservoir (7) which has an upper section (15), a lower section (17) and a marker level sensor (8) located at a narrow constriction between the two sections (15, 17). The apparatus includes a blender (21) which causes fluid flow to occur at different rates and is operable so that the slugging effect of marker injection is reduced. The injector pump (10) is arranged to provide a delay prior to each forward or reverse stroke. The memory devices of the controller (13) are locked or sealed so as to deny access to reprogramme the controller (13).

L'invention concerne un véhicule de livraison permettant de fournir un carburant liquide avec ou sans marqueur, ce véhicule comprenant un appareil avec un réservoir (7) de marqueur et une pompe d'injection (10) pour ajouter un marqueur au carburant liquide. Un dispositif de contrôle (13) enregistre un événement associé au vidage du réservoir (7), celui-ci ayant une section supérieure (15) et une section inférieure (17), avec un détecteur de niveau (8) dans une partie resserrée entre les deux sections (15, 17). L'appareil comprend un mélangeur (21) permettant de faire circuler le fluide à différents débits et servant à éviter la persistance de masses mal dispersées de marqueur. La pompe d'injection (10) est conçue pour permettre un délai avant chaque mouvement vers l'avant ou vers l'arrière. Les mémoires du dispositif de contrôle (13) sont verrouillées ou fermées, de manière à interdire l'accès au dispositif de contrôle (13).
