ABSTRACT:
Positive displacement pumps, each having multiple pistons reciprocated by a swash plate, are connected to corresponding liquid reservoirs and are individually actuated to dispense a selected liquid type and pour size volume through a hand held gun. A digital control circuit receives feedback from an emitter, detector, chopper wheel combination associated with each pump to monitor the amount of liquid dispensed. The control circuit also monitors the actuation of switches on each dispensing gun and causes the desired pour size volume of the selected liquid to be dispensed. Pour size volume and pricing information may be programmed through a keyboard coupled to the control circuit and accounting information may be displayed or printed on command.
