Abstract

A railroad tank car is calibrated by continuously adding liquid into the tank car from a liquid supply means. The amount of liquid is measured by meter means as the liquid is being continuously added. Depth sensor means continuously determines the depth of liquid in the tank car. A computer is used to monitor the instruments and to obtain a measure of the volume of liquid in the tank car at pre-determined depths and to correlate the volume measure with the measured depth.
