Abstract
A chemical product dispenser dispenses a chemical product having at least one active ingredient during a primary dispense cycle based on time or some other factor. After the chemical product has been dispensed, the dispenser determines the amount of chemical product that was dispensed. The dispenser then determines whether the dispensed amount of chemical product is within a defined threshold of a desired amount. If not, the dispenser proceeds to dispense additional chemical product during one or more make-up dispense cycles until the threshold is satisfied.
