Abstract: A beverage dispenser for filling a container preferably has a nozzle through which the beverage is discharged and a pivoting lever located underneath the nozzle that detects the placement of a container so as to regulate the actuation of the dispenser. A conductive probe is in line with the discharged beverage stream, the lever also being conductive. A signal generator generates a varying-over-time signal that is applied to the probe or lever. As a result of beverage overflowing the container, the beverage stream establishes a conductive path between the probe and lever. The signal through this conductive path is compared to the signal produced by the signal generator. If the signals are substantially identical for a select period of time, the dispensing system is considered to be in an overflow state, and beverage dispensing is terminated.
