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.

[ What is claimed is:] [1.] A device for dispensing a first liquid and a second liquid in a desired ratio, comprising:a first conduit for delivery of the first liquid;a second conduit for delivery of the second liquid;a mixing chamber in communication with each of said first and second conduits for receiving the first and second liquids;a first valve associated with said first conduit for controlling a first rate of fluid flow through said first conduit;a second valve associated with said second conduit for controlling a second rate of fluid flow through said second conduit;at least one flow meter operably associated with said first and second conduits for measuring said fluid flow through said conduits; anda control system responsive to said flow meter and operably associated with said valves for controlling, in an open loop fashion, said valves such that said fluid flow through said conduit is controlled in a manner such that the flow of said fluid through said conduit is modified when it differs from the flow through the other one of said conduits by a predetermined amount, whereby a predetermined flow ratio of the first liquid to the second liquid is maintained.
