The method and apparatus of the invention may be used to add additive, such as dye, to a fluid such as fuel, by means of a pump (8) and a duct (4, 5) through which the fuel flows. The pump (8) is operable to add dye to the fuel in discrete or regularly varying amounts. A light beam is generated by light emitter (16), enters inspection chamber (12) where the dye is added and exits the chamber (12) where it is received by external receiver (17). The light emitter (16) and receiver (17) are connected to a light sensor (15) which is operable to detect one or more types of change in a characteristic of the light beam when it is passed through the fuel.

La pompe (8) permet l'adjonction de colorant en quantités discrètes ou régulièrement variables. Un faisceau lumineux produit par un émetteur (16) de lumière entre dans la chambre d'inspection (12) où est ajouté le colorant qui, sortant de la chambre (12), est reçu dans un réceptacle (17) extérieur. L'émetteur (16) et le réceptacle (17) sont reliés par un photocapteur (15) qui détecte un ou plusieurs types de modification des caractéristiques du faisceau lumineux lorsqu'il traverse le carburant.
