Abstract
Procédé et appareil de mesure de la concentration d'un composant dispersé dans un fluide en mouvement comportant les étapes suivantes: (a) émission d'un faisceau lumineux sur une gamme prédéterminée de longueurs d'ondes en direction de l'échantillon de fluide à analyser tandis que ledit fluide traverse une sonde de mesure, (b) sélection de certaines longueurs d'ondes à l'intérieur de la gamme susdite, (c) mesure de différentes intensités lumineuses tandis que ledit fluide traverse la sonde dont sont extraits un certain nombre d'ensembles de mesures d'intensités lumineuses correspondant aux différentes longueurs d'ondes, (d) mesure de différentes intensités lumineuses tandis que ledit fluide traverse la sonde dont sont extraits un certain nombre d'ensembles de données de référence consistant chacun en mesures d'intensité lumineuse correspondant aux différentes longueurs d'ondes (e) extraction à partir des données ainsi obtenues d'informations sur la concentration du composant dispersé dans le fluide en mouvement.
