Abstract
A chemical dispensing assembly having injector assemblies that combine a solvent stream with a concentrate stream within a Venturi injector assembly to produce a chemical solution outlet stream. Each injector assembly has an interchangeable metering assembly that limits the flow of concentrate into the Venturi injector assembly to change the resulting concentration of the concentrate within the solution outlet stream. The chemical dispensing assembly also has a keyed connector system that prevents the connection of the wrong concentrate container to the wrong injector assembly.
