초록

A beverage dispenser with an out of syrup detector is described. The detector analyzes the electrical current drawn by a solenoid valve controlling the flow of syrup. Parameters of the current are compared to known parameters indicative of proper back pressure and known parameters indicative of an out of syrup condition.
