Abstract: A dispenser is programmed to automatically dispense a beverage into a plurality of different size containers by storing therein a volume designation for each size container. The flow rate of beverage through the dispenser is determined. To do so, a user manually operates the dispenser to fill a given container with the beverage while the dispenser measures the filling time. The dispenser calculates a beverage flow rate from the volume designation for the given container and the filling time. Then the flow rate and volume designations are used thereafter by the dispenser to derive a dispensing time for each different size container. Thus the dispenser is able to derive dispensing times for each container size from filling only one of the containers. A unique dispenser valve also is disclosed.
