Abstract
Abstract A computer controlled sensor for a beverage dispenser in which a micro-processor receives inputs from one or more sensors for detecting the size of a beverage cup which is to be filled by a dispensing unit and which, depending upon the size of the cup, energizes a dispensing valve so as to fill either a small, medium or large size cup for example. A memory is provided which controls the micro-processor in response to the detected size of cup which is to be filled and a Hall sensor is utilized for initially setting the quantity of liquid which is to be dispensed.
