1. A characterized liquid gaging system sensor, comprising:

  • sensor means for sensing a depth of liquid in a tank at a particular location in the tank; and

    storage means for storing characterization parameters, each parameter defining a relationship between a liquid depth and a value related to a liquid quantity, each parameter being based on tank shape and volume, on the location of the sensor means, and on a physical condition which affects the accuracy of the value related to the liquid quantity, the storage means comprising means for storing look up tables, there being a first look up table for storing a first set of parameters and a second look up table for storing a second set of parameters, the first and second set of parameters each representing a different best fit between the physical condition and the value related to the liquid quantity, the storage means being connected to the sensor means.
