초록

An apparatus for measuring and displaying a time interval between a valve closure and subsequent termination of a flow at a spigot is provided. The apparatus has magnetic sensors coupled to a flow regulating valve for providing a signal indicative of a solenoid-activated valve closure and detectors for determining fluid flow. The detectors have an infra-red light source and associated photo-sensor mounted near the water outlet spigot such that when a fluid flow is present at the spigot, the fluid reflects light from the infra-red light source so that the...
