Abstract
A method and system for formulating and dispensing a chemical product to a dispense location is disclosed. The chemical product is formulated using one or more chemical concentrates. The chemical concentrates may be stored in concentrate containers and provided to a formulator by associated concentrate pumps. The concentrates are pulled from the containers through a manifold and to the formulator. The formulator discharges the chemical concentrates through a dispense hose having an outlet valve to the dispense location. The dispense location may be a jug or a drum. A flow meter connected between the formulator and the dispense hose. The flow meter monitors the component chemical concentrates flowing through the dispense hose and measures volumetric information associated with each component chemical concentrate. A flow controller analyzes the volumetric information generated by the flow meter and controls the volume of each component chemical concentrate dispensed to the dispense location.
