Abstract
A method and apparatus for blending and dispensing fluids with multi-directional selector valves, a single meter, and a mechanism for purging the dispenser. The single multi-directional selector valve and single meter is used for reducing the number of leakage points in a dispenser, to simplify the dispenser, and to reduce the production cost of the dispenser. Purging is used for decontaminating the fluid dispenser of fluids previously used by the dispenser and to ensure proper fluid grade.
