An automatic cup-filling control arrangement for beverage dispensers utilizes the spray or mist of liquid droplets, formed by flowing beverage striking beverage already in the cup, to complete an electrical circuit. This electrical circuit extends from an electrically conducting member, such as an actuating lever, to beverage flowing through a dispensing valve. When the mist of droplets permits a pre-established magnitude of current to flow between the actuating lever and the flowing beverage, which occurs when beverage in the cup reaches a pre-determined level, dispensing of the beverage is terminated.

A beverage dispenser having an arrangement for automatically controlling the filling of a cup comprising: at least one source of beverage; at least one valve means for controlling discharge of beverage from said source into the cup to be filled; actuating means to cause said valve means to be energized to initiate dispensing of the beverage into the cup to be filled; an electrically conductive member associated with the beverage dispenser and disposed to be positioned adjacent to and outside of the cup that is being filled; circuit means electrically interconnecting said electrically conductive member and said valve means to thereby electrically interconnect said conductive member with beverage flowing through said valve means; and control means for operating said valve means in response to a change in impedance between said electrically conductive member and the beverage, when the cup has been filled to a pre-determined level, to discontinue beverage flow to the cup.
