ABSTRACT:
A photoelectric sensor circuit may be provided for a soft drink dispenser for indicating when a supply tank within the dispenser has run dry of fluid. Said circuit employs preferably an orthogonal reflection photosensor for sighting through the supply line for triggering an electronic relay which operates audio and visual alarms and for triggering additional control signals to the dispensing machine control box for altering the operation of the dispensing machine when it has been determined that the supply line is empty.
