Abstract

La présente invention concerne un procédé de mesure de la perméabilité des milieux filtrants, caractérisé en ce que : 1 degrés on préforme un gâteau en introduisant sous pression dans un porte-gâteau une suspension du milieu filtrant jusqu'à ce que le sommet du gâteau englobe au moins en partie deux électrodes 12 et 12a de mesure; 2 degrés lesdites électrodes 12 et 12a sont convenablement reliées à un circuit électrique en vue de couper la pression de telle sorte que le gâteau ne subisse pas de début d'assèchement. 3 degrés on arase ledit sommet et on effectue la mesure de la perméabilité. La présente invention concerne également un appareillage pour la mise en oeuvre dudit procédé ci-dessus.
