Abstract:
A meter system for a water treatment device, the device having an inlet aperture and an outlet aperture, and a channel for channeling flowing water between the inlet and outlet apertures, the meter system comprising:a flow reactive device; a signal generating member causing said flow reactive device to produce a spatially varying signal in reaction to water flow; a sensor generating a flow signal corresponding to water flow in the channel; an output device for indicating when the water treatment device is usable; and a controller coupled to receive and accumulate the flow signal, and including a plurality of thresholds, with at least one of said thresholds representing a delay function during water flow, said controller comparing the accumulated flow signal to said thresholds, the controller not actuating the output device when the accumulated flow signal is below said threshold representing a delay function, the output device thus indicating the delay function, and the controller activating the output device when the accumulated flow signal exceeds at least one of said thresholds other than said threshold representing a delay function.
