ABSTRACT:
The assembly of the present invention includes a liquid dispensing device having conduit means for delivering liquids from a storage chamber to a mixing chamber, from which the liquid product is dispensed, and valve means incorporated in each conduit. The assembly further includes a flow meter for each liquid which operates to produce an output signal proportional to the quantity of liquid flowing through the conduit. A control means receives the output signals and operates on detecting that flow of one liquid exceeds a predetermined amount, by closing the flow control valve associated with that liquid. Upon detecting that the proper proportion is achieved, the control means signals the valve to reopen.
