Abstract
A system for signaling emptying of a beverage storage container of a beverage dispensing system before any substantial amount of gas enters the delivery line between the container and a dispensing valve. No signal system components are in the container; instead, a fitting is mounted in the delivery line adjacent the container with two electrodes spaced from and electrically insulated from one another within the fitting for contact with the beverage. Sensing circuitry determines whether beverage bridges the two electrodes and causes signaling on non-bridging of the two electrodes by beverage in the line to indicate that the container is empty.
