Title (EN) SYSTEM AND VALVE FOR WATER USE MONITORING AND CONTROL
(FR) SYSTÈME ET SOUPAPE POUR SURVEILLANCE ET COMMANDE D'UTILISATION D'EAU
Abstract:
(EN) A valve assembly capable of converting a small leak of a device into a measurable, relatively larger or "burst" flow event is described. In certain embodiments, the valve assembly includes a compliant chamber and, following pressurization of the device, permits flow when the pressure in the compliant chamber drops to a configured fill pressure and restricts (or prevents) flow when the pressure in the compliant chamber increases to a shut-off pressure. The disclosed valve assemblies may be incorporated into a leak detection assembly capable of transmitting usage and/or alarm data to a central service.
(FR) Ensemble soupape pouvant convertir une petite fuite d'un dispositif en un événement d'écoulement mesurable, relativement plus grand ou "rafale". Selon certains modes de réalisation, l'ensemble soupape comprend une chambre souple et, après la mise sous pression du dispositif, permet un écoulement lorsque la pression dans la chambre souple chute à une pression de remplissage configurée et limite (ou empêche) l'écoulement lorsque la pression dans la chambre souple augmente jusqu'à une pression d'arrêt. Les ensembles soupapes décrits peuvent être incorporés dans un ensemble de détection de fuite pouvant transmettre des données d'utilisation et/ou d'alarme à un service central.
