ABSTRACT:
The invention is an improved liquid measuring device which can be used as a proportioner, dispenser or flow meter for a single fluid or for an unlimited number of fluids. The device embodies a free-floating piston sealed within a cylinder capped at both ends, a high-resolution detector system, either optical or electrical, to accurately determine the piston location within the cylinder, and a microprocessor which converts the lateral movement of the piston within the cylinder into volume measurements of the fluid in the cylinder.
