Abstract
A method includes measuring tensions on a measuring wire coupled to a displacer of a servo gauge. The servo gauge is configured to raise and lower the displacer using a drum around which the measuring wire is wound. Different measured tensions are associated with different segments of the measuring wire. The method also includes calculating or adjusting a measurement associated with material in a tank using the measured tensions to account for a change in a length of the measuring wire. Calculating or adjusting the measurement could include calculating one or more first length adjustments for one or more segments of the measuring wire that are wound around the drum, calculating one or more second length adjustments for one or more other segments of the measuring wire that are unwound from the drum, and combining the first and second length adjustments to identify a final length adjustment.
