A system and method for selecting one of a plurality of liquid supply receptacles as a source of supply for a liquid dispensing apparatus is disclosed. As liquid is withdrawn from the supply receptacle the dielectric constant of the liquid is sensed in order to detect any undissolved gases (i.e., bubbles) which are present in the liquid. The presence of bubbles within the liquid indicates that a supply receptacle has become empty or indicates a failure of components associated with one of the supply receptacles. Upon the detection of undissolved gases within the liquid withdrawn from a supply receptacle, the present invention causes another liquid supply receptacle to be selected as a source of supply for the liquid dispensing apparatus. Embodiments of the present invention desirably also include switches for manually inputting when a liquid supply receptacle has been refilled or replaced, indicators for visually showing the status of the system, and a remote annunciator for communicating the status of the system to a point remote from the liquid supply receptacles.
