Abstract

La présente invention concerne un système de surveillance d'un réseau de distribution de fluide (10) comprenant une génératrice hydroélectrique (12) alimentant le système, un débitmètre pour eau (14), et éventuellement un dispositif de communication (16). La génératrice (12) est placée sur un tuyau de fluides (18) du système de réseau de distribution, de sorte que le flux de fluides traversant le tuyau (18) entraîne la génératrice (12) pour produire de l'électricité. Ce système (10) convient particulièrement à un système de distribution d'eau, capable de mesurer par rapport à un réseau de distribution d'eau un débit minimum, un débit maximum, un débit instantané à n'importe quel moment, un débit total pendant une période précise, et la demande de crête moyenne.
