Abstract

L'invention concerne un procédé pour mesurer le volume des matières en suspension dans un liquide d'une granulométrie inférieure à une valeur prédéterminée Selon ce procédé, on éclaire un échantillon dudit liquide à l'aide d'un faisceau laser, ce faisceau étant diffracté à la traversée de l'échantillon, on mesure le flux lumineux diffracté dans au moins deux fenêtres de diffraction à l'aide de cellules photoélectriques et on additionne électriquement les signaux pondérés fournis par lesdites cellules photoelectriques.
