1. A liquid gaging system, comprising:
- a probe for mounting in a tank, the probe having a length, the probe for a particular tank producing a length signal dependent upon the portion of the probe being immersed in liquid;
means for receiving an attitude signal related to an attitude of the tank;
storage means for storing data related to tank shape, volume, and attitude and to probe location; and
determining means for determining a value related to a liquid quantity in the particular tank based on the length signal, the attitude signal, and the data, the determining means being connected to the probe, the means for receiving, and the storage means.

Abstract
A liquid gaging system including a probe for mounting in a tank. A probe for a particular tank produces a length signal dependent upon the length of the probe being immersed in liquid. The system also includes a storage apparatus for storing characterization parameters and a determining apparatus for determining liquid volume in the particular tank based on the length signal and the characterization parameters. In addition, the system includes an apparatus for connecting the storage apparatus to the determining apparatus and an apparatus for connecting the probe to the determining apparatus.
