Abstract
a. Dispositif indicateur du niveau de liquides dans des récipients. b. Le dispositif indicateur comporte un agencement photo-électrique disposé à l'extrémité d'un barreau transparent opposée à l'extrémité plongeant dans le liquide et constitué par une source et un récepteur de lumière, mis en liaison avec un montage électrique actionnant un dispositif avertisseur lors d'une variation du comportement de réflexion de l'extrémité de détection du barreau. c. Application à la détection du niveau de l'acide dans une batterie.
