Abstract

An automatic dispensing method and apparatus for transporting separate concentrated chemicals to the site of use and then dispensing the concentrated chemicals into a storage container to create a final or intermediate composition. The automatic dispensing apparatus includes a computer program that calculates the appropriate formulation and then interfaces with a controller to cause the appropriate chemical concentrates and the appropriate volumes of those concentrates to be dispensed. A method of generating a desired formulation is also disclosed and claimed.
