Abstract

Procédé de mesure de niveau d'un liquide 4 électriquement conducteur contenu dans un réservoir 6 muni d'un fond 8, consistant à mesurer la distance verticale parcourue par une électrode mobile 12 entre le niveau du fond 8 et le niveau de la surface du liquide, ces deux niveaux étant détectés en contrôlant les variations de résistance électrique entre l'électrode mobile 12 et le fond 8, la résistance électrique devenant quasi nulle lorsque l'électrode mobile 12 vient au contact du fond 8 et la résistance électrique subissant une variation brusque lorsque l'électrode mobile 12 vient au contact de la surface du liquide. L'invention concerne également un limnimètre utilisant ce procédé. (CF DESSIN DANS BOPI)
