A beverage dispenser for dispensing either a hot or cold beverage, for example tea, from a common mixing chamber and a method for making and/or operating the same is disclosed. The dispense has a source of hot water, usually a heater, and a source of water, a refrigeration system to cool the water and one or more sources of flavor. The hot or cold water, or both can be provided to the common or same, mixing chamber and mixed assisted with a static and/or dynamic mixer and then dispensed. The last portion of the water is used to rinse for the next beverage. Flavor or syrup pump current is sensed to provide the appropriate amount of flavor concentrate to a known quantity of water to form a beverage of appropriate strength or syrup.

A system and method of flow rate compensation is provided to allow precise volume dispensing over widely varied and varying input process media pressure and flow conditions. This system utilizes empirical data of actual flow rate versus flow rate measured by a flow meter to characterize flow meter non-linearities. This data is used to generate a compensation control curve. The system controller receives flow data from a flow meter in the field and calculates pulse duration of the output of the flow meter. The compensation control curve is then used to determine the volume of process media flowing at any given time. This instantaneous volume information is added to an accumulator to determine the volume of process media dispensed. This volume is compared to a target volume. Once this target volume is reached, the flow of process media is stopped.
