ABSTRACT:
A method and system for determining a product level in a tank which determine a first level measure using emission of electromagnetic waves into the tank, detect a differential pressure, determine an observed density based on the detected differential pressure and the first level measure, and determine a second level measure based on the observed density and a currently measured differential pressure. The present invention is based on the realization that a level measurement based on differential pressure and an observed density can provide a valuable redundant level measurement, which can provide increased reliability and enable detection of errors.
