Abstract
Described herein is a chemical injection system and method utilizing a chemical storage vessel coupled to a bulk source of chemical and proportioned to contain a volume of chemical useful for multiple applications for which the chemical is to be utilized. A dispense vessel proportioned to contain a volume of chemical useful for a single application is fluidly coupled to the chemical storage vessel. A controller controls operation of a system of valves and sensors, which operate to fill the chemical storage vessel, and to precisely dispense the volume required for a single application from the storage vessel into the dispense vessel and then ultimately into the vessel in which the chemical is needed.
