ABSTRACT:
A system and method is disclosed for controlling concentration of a component chemical product in a chemical solution. The chemical solution is formed in a solution tank by combining the component chemical product with water. The component chemical product is dispensed to the solution tank by a chemical dispenser that is controlled by measured conductivity readings of the chemical solution taken in the solution tank. The conductivity readings are analyzed against a conductivity setpoint to determine whether the component chemical product should be added to the chemical solution. A conductivity offset is determined and applied to the analysis thereby taking into consideration any conductivity that may be attributable to constituents of the chemical solution other than the component chemical product. Such constituents include soil washed from the articles and the water used to form the chemical solution.
