  • Patent number: 10606286
    Abstract: A dispenser system including a source of chemical concentrate, a source of diluent, and a mix chamber in fluid communication with the source of chemical concentrate via a first line and with the source of diluent via a second line to mix chemical concentrate and diluent to form a dilution. The dispenser system also includes one or more metering devices disposed in one or both of the first line and the second line, a discharge fluidly coupled to the mix chamber to deliver the dilution to a downstream receptacle, and a control system in communication with the one or more metering devices. The control system is programmed to adjust a concentration of chemical concentrate in the dilution via control of the one or more metering devices based on an environmental factor affecting a physical environment to be cleaned using the dilution.
