RFID controlled chemical porportioner and dispenser

A method of dispensing a selected chemical from a chemical source container at a chemical source station in a dispenser including a plurality of chemical source containers at respective chemical source stations, each container at a source station providing machine readable data representing information specific to the chemical therein, said dispenser having a multiple position selection switch with respective positions operably connected to select a particular chemical source station for dispensing of a chemical in a container therein, said method comprising:

• programming a controller with a data library comprising data for a plurality of selectable chemicals to be dispensed from respective ones of a plurality of chemical source stations;
• operating said selector switch to one position associated with a chemical source station;
• comparing the data from the chemical source container at said station selected to said data library to confirm the data from the chemical source selected matches one of the chemical data in the library for said source station;
• and
• dispensing the chemical to a receiving container providing machine readable data corresponding to the information from the selected chemical source container.

A dispenser for dispensing selected chemicals from a selected one of a plurality of chemical sources and including:

• a plurality of chemical source stations;
• a chemical source container in at least one of said stations and providing a data signal representative of a chemical in said container at said station;
• a selector switch having a plurality of positions respectively associated with a respective station for selecting a chemical source for dispensing from said respective station;
• a data library programmable with data for chemicals acceptably associated with each station;
• a diluents valve operable to draw chemical from a selected chemical source at said respective station said selector switch interconnecting data from said library for a station to a data signal from a chemical source container at said station for comparison of said data and said data signal when data from said container at said station matches data of one of the chemicals in said data library for the selected chemical source station and dispensing said chemical.
