<p>A method includes retrieving (216) at least one first measurement associated with material (104) in a tank (102) from a memory (122) at a level gauge. The method also includes comparing (304) the at least one first measurement to at least one second measurement associated with the material in the tank. The method further includes determining (306) whether a difference between the at least one first measurement and the at least one second measurement exceeds a threshold. In addition, the method includes identifying a current level of the material in the tank in a first manner (308-312) if the difference does not exceed the threshold or a second manner (316-322)if the difference does exceed the threshold. The first manner could include correcting (312) a level measurement using the difference between the at least one first measurement and the at least one second measurement. The second manner could include identifying an offset value (318-320) based on differences between pairs of level measurements.</p> |
