Abstract: The amount of beverage dispensed from each of a plurality of reservoirs in units at a plurality of remote locations, such as hotel rooms, is controlled and indicated. A central console, such as a hotel front desk, includes a keyboard for deriving data and command signals, as well as a data processor that responds to the data and command signals to derive addressing and command signals for the units. A display at the central console responds to the keyboard data and command signals to display the keyboard data signals, as well as data signals derived from addressed units. At each of the units, a liquid flow controller for each reservoir responds to an output of a data processor at the unit. The unit data processor responds to a customer input and command signals from the console to activate the flow controller. In response to a unit being addressed by the console, the unit data processor supplies signals to the console to indicate the amount of beverage dispensed from the reservoirs.
