Abstract

La présente invention concerne un compteur d'eau comprenant un compteur électrique équipé d'un mécanisme d'entraînement intermittent et un boîtier de compteur (1). Un tuyau d'admission (2) et un tuyau d'échappement (3) arrivent au niveau de la partie inférieure du boîtier et un rotor (5) est disposé à l'intérieur de celui-ci. L'arbre de sortie du rotor est relié par couplage magnétique au second engrenage intermédiaire via le premier engrenage intermédiaire. Le second engrenage intermédiaire est relié au mécanisme d'entraînement du compteur électrique. Ledit mécanisme d'entraînement du compteur électrique est constitué de plusieurs éléments de commande et éléments commandés représentant diverses décades. En outre, l'élément de commande et l'élément commandé de la même décade sont reliés à une unité entière. L'élément de commande comme l'élément commandé de la décade la plus basse du dispositif de comptage constituent l'engrenage primaire du second engrenage intermédiaire. L'élément commandé de la décade immédiatement supérieure constitue l'engrenage final du second engrenage intermédiaire. La décade supérieure du dispositif de comptage ne comporte qu'un élément commandé. Les multiples éléments de commande et éléments commandés sont partiellement ou totalement équipés de plaques de type résistance et un dispositif de lecture peut déterminer la valeur de ladite résistance. Par rapport à l'art antérieur, le compteur d'eau selon la présente invention peut réduire le couple actif, améliorer la précision du compteur et abaisser les coûts.
