Claim:
1. A liquid dispenser station comprising: a filler including a filler outlet for delivering a liquid; a sensor assembly configured to provide a sensor assembly electronic signal indicative of object presence proximate the filler outlet; and a controller configured with a processor and a computer readable medium including computer executable instructions for carrying out a set of liquid dispenser station management operations, wherein the controller is configured with computer executable instructions for performing filler control operations for managing flow of liquid via the filler when in object is detected by the controller based upon the sensor assembly electronic signal indicative of an object proximate the filler outlet, and wherein the computer executable instructions for performing the filler control operations comprises executable filler control logic that, while operating in an off state characterized by no flow of liquid via the filler outlet, continuously generates a zero level signal value corresponding to a clear field of view for the sensor assembly, the zero level signal value being calculated from multiple samples of the sensor assembly electronic signal indicative of object presence proximate the filler outlet.
