ABSTRACT:
A sensor apparatus for sensing an out-of-syrup condition in association with a machine for dispensing a beverage and in which the beverage is constituted of a syrup concentrate and water. The sensor comprises a housing having a through passage and a transverse hole which receives a cap for supporting a probe that extends partially into the through passage. The probe is preferably disposed vertically and operates on a gravity principle so that when the syrup is depleted, a gap forms and the syrup liquid essentially breaks away from the probe causing a high resistance indication that is detected.
