<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 a predetermined volume of syrup, 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 acccurately be set at the same time as the ratio.</p> |
