Abstract: A dispenser system is disclosed comprising a liquid dispenser pump, an electronic circuit for controlling the dispenser system, and a dispenser for dispensing a flowing liquid through a metering orifice. The dispenser system enables mixing and dispensing of a first and a second liquid in accordance with a given volumetric relationship between the first liquid and the second liquid. The system includes flow for controlling the flow of the first liquid and a pump for pumping a second liquid. The electronic circuit includes a generator for generating an electrical pumping signal to power the pump for pumping the second liquid in accordance with an electrical pumping signal. An activator is connected to the flow and the generator for activating simultaneous flow and pumping of the first and second liquids, respectively, upon a selected signal from the activator.
