Abstract
Procédé et appareil pour l'indication du niveau atteint dans un réservoir par un liquide conducteur de l'électricité. On dispose dans le réservoir une bobine de support 1, à dimension transversale moyenne de 20 à 45 mm, portant un fil résistant 2 enroulé de façon à avoir une valeur ohmique de 3 à 32 ohms par millimètre de longueur de bobine. Quand le niveau monte, le liquide relie des spires successives du fil résistant, ce qui modifie l'impédance aux bornes de ce fil. On mesure ce changement d'impédance et on le convertit en un résultat affiché qui indique le changement de niveau. Application notamment à des installations de traite pour la mesure de la production individuelle des laitières.
