Title
(EN) SYSTEM FOR DETECTING AND/OR CONTROLLING A WATER LOSS IN A WATER SUPPLY NETWORK
(FR) SYSTÈME SERVANT À LA DÉTECTION ET/OU À LA COMMANDE DE PERTE D'EAU DANS UN RÉSEAU D'ALIMENTATION EN EAU
Abstract
(EN)
The present invention relates to a system (1) for detecting and/or controlling a water leak in a water supply network (RI), of the type comprising: - a body (10) having a first portion (11) for letting a water flow (F) enter the body (10), an intermediate portion (101) for the transit of said flow (F) within the body (10), and a second portion (12) for letting said flow (F) exit the body (10); - a sensor (20) associated with the body (10) for detecting the passage of said flow (F); - a control device (30), in particular of an electronic type, adapted to process a signal (S) relating to the detected flow (F) and coming from said sensor (20); - an intercepting device (40) adapted to receive a control signal (SC) from said control device (30) in order to selectively allow or prevent the passage of said flow (F). The present invention is characterized in that said sensor (20) consists of a thermal- dispersion flow meter.
(FR)
La présente invention se rapporte à un système (1) servant à la détection et/ou à la commande d'une fuite d'eau dans un réseau d'alimentation en eau (RI), du type comprenant : - un corps (10) possédant une première partie (11) destinée à permettre à un écoulement d'eau (F) d'entrer dans le corps (10), une partie intermédiaire (101) destinée au transit dudit écoulement (F) dans le corps (10), et une seconde partie (12) destinée à laisser ledit écoulement (F) sortir du corps (10) ; - un capteur (20) associé au corps (10) destiné à la détection du passage dudit écoulement (F) ; - un dispositif de commande (30), en particulier d'un type électronique, conçu pour le traitement d'un signal (S) se rapportant à l'écoulement détecté (F) et venant dudit capteur (20) ; - un dispositif d'interception (40) conçu pour la réception d'un signal de commande (SC) dudit dispositif de commande (30) afin de permettre ou d'empêcher le passage dudit écoulement (F) de manière sélective. La présente invention est caractérisée en ce que ledit capteur (20) se compose d'un débitmètre à dispersion thermique.
