A beverage dispenser is described which has a faucet with a spout, a fitting for connection to a beverage supply and a lever operated valve. A servo motor, coupled to the lever, operates the faucet and proportionally controls the flow of the beverage. The proportional flow control manages the amount of beverage foaming. A flow sensor has a magnetic turbine within the faucet and a Hall effect element that magnetically senses turbine motion and produces a signal indicating an amount of beverage flow. A keypad enables service personnel to designate various portions of the beverage to automatically fill serving containers of different sizes. A control circuit responds to activation of the keypad and to the flow sensor by operating the servo motor to dispense the related quantity of the beverage.
