摘要
A sensor is coupled to a reservoir for generating a first signal responsive to the liquid level therein falling below a first level spaced above an output port and indicative of a reserve level of liquid remaining. A pump is coupled to the reservoir for pumping the liquid therefrom in metered volumes and responsive thereto transmitting a volume pumping signal. An integrator receives and integrates the volume pumping signal, and then generates, after receiving the first signal, an output signal indicative of the volume of the liquid remaining in the reservoir. An indicator is coupled to the integrator for displaying the output signal.
