A system controls dispensing different chemicals received from containers at a plurality of ports. Each container has data thereon that identifies the chemical within the container. The system reads the data from each container to determine which port is associated with each chemical. When a given chemical is required, the system activates a flow control device coupled to the port associated with that given chemical, thereby supplying the given chemical to a consuming device. Therefore regardless of into which port an operator places a particular chemical, the system automatically knows which port has which chemical and the dispensing is configured accordingly. Various mechanisms for storing the data on and reading the data from the container are described. |
