ABSTRACT:
A dispensing system responds to reading data stored on a container by determining a dose for a chemical stored in that container. Then each time that the chemical is to be fed into a cleaning machine, the dispensing system operates a flow control device to deliver the designated dose. Thus the dispensing system is automatically reconfigured when different concentrations of the chemical are supplied to the dispensing system. Various mechanisms for storing the data on and reading the data from the container are described.
