ABSTRACT:
A fluid overfill and identification system uses a pulsed signal to both detect an overfill condition and identify a fluid product contained in a compartment. The pulsed signal is converted into an optical pulsed signal which is used with a retroreflective prism to detect when a fluid in the compartment has reached a desired capacity. Encoded in the pulse width of the same pulsed signal is the specific fluid product located in the compartment. Furthermore, different pulse frequencies are provided depending on whether the tanker truck is at a service station or at a loading terminal, thus allowing the system to distinguish between the two. At a marketing terminal, a new code is loaded into the system as a new fluid product is loaded into a compartment. A residue sensor may detect residual fluid in the compartment, and prevent the loading of a new fluid product and a new ID code.
