Abstract

L'invention concerne un procédé pour la détermination analytique de la granulométrie de solides dispersés ou de la grosseur de gouttes de liquide qui tombent. Procédé caractérisé en ce qu'on mesure instantanément la grosseur et/ou la masse et/ou la teneur en chaleur et/ou d'autres caractéristiques éventuelles des particules qui tombent, s'écoulent ou sont distribuées de façon stationnaire, pendant leur séjour dans une zone de mesure 9, au moyen d'un ou plusieurs appareils capteurs 10 braqués éventuellement de différentes directions, en ce qu'on classe les valeurs mesurées dans différentes gammes prédéterminées, en ce qu'on additionne ces valeurs au sein des gammes et en ce qu'on mémorise les valeurs additionnées de façon qu'elles puissent être appelées individuellement - ou en plus d'autres valeurs mesurées de la gamme considérée - pour être affichées et/ou interprétées.
