ABSTRACT:
A dosing system for precisely mixing two liquids in a predetermined volumetric relationship includes a flow meter having a fluid inlet, a fluid outlet, and two intermeshed counter-rotating gears positioned between the inlet and outlet. When a first fluid is directed from the inlet to the outlet, the first fluid causes the gears to turn, and the gears turn a predetermined amount for each unit of first fluid directed through the f low meter. The rotor of a peristaltic pump is coupled to one of the gears of the flow meter, such that for each increment of rotation of the gear, the rotor turns to pump a predetermined amount of a second fluid through the peristaltic pump. The outlets of the two pumps are in fluid communication, to permit mixing of the predetermined amounts of first and second fluid.
