<p>A microprocessor based control system including an electrical unit attached to a postmix beverage dispensing valve for performing the three functions of: portion control, reminding the operator to check the ratio, and adjusting the ratio. The portion control operation can be identical to known portion control devices. The reminder function can turn on a light every two weeks, for example. In the ratio adjusting function, the operator puts a single cup under the valve, pushes "Small" to dispense syrup for a predetermined time period which should result in the dispensing of a predetermined volume of syrup, measures the exact volume actually dispensed, and then adjusts the syrup flow control accordingly until the exact predetermined volume is dispensed, and repeats the operation for water in the same cup but to a different predetermined volume. The flow rate can accurately be set at the same time as the ratio.</p> |
