Title (EN) PROCESS AND DEVICE FOR THE MEASURING OF COLOUR AND/OR PARTICLES IN A FLUID
(FR) PROCEDE ET DISPOSITIF DE MESURE DE LA COULEUR ET/OU DES PARTICULES DANS UN FLUIDE
Abstract:
(EN) A method for detecting a coloured fluid, e.g. coloured diesel fuel, in a non-coloured fluid by emitting light of two different wavelengths into a sample of the fluid and measure the absorption. The coloured fluid absorbs light at one of the selected wavelengths, and by relating the two absorption values the coloured fluid can be detected. A probe comprising LEDs and focusing lenses suitable for the measurement is also described. The probe can also be used in a method for measuring of particles in a fluid.
(FR) L'invention concerne un procédé permettant de détecter un fluide coloré, p. ex d'un fluide diesel, dans un fluide non coloré. Ce procédé consiste à projeter une lumière de deux longueurs d'ondes différentes dans un échantillon de fluide et à mesurer son absorption. Le fluide coloré absorbe la lumière à une des longueurs d'ondes sélectionnée et on peut détecter le fluide coloré en mettant en rapport les deux valeurs d'absorption. L'invention concerne également une sonde comprenant des DEL et des lentilles de focalisation, permettant d'effectuer ces mesures. Cette sonde peut également être employée dans un procédé permettant la mesure des particules dans un fluide.
