Abstract
A method and apparatus for measuring the level of a liquid in a storage tank having a predetermined reference level. A liquid level sensor is located in the tank so as to monitor the upper level of liquid over a predetermined height range at a plurality of locations within the tank. The sensor is interrogated at each location to determine the corresponding sensed level and the sensed levels are compared to see if their values are close enough to indicate that the measured level approximates a plane parallel to the predetermined reference level in the tank. Only when the sensed evels are close enough in value, is one of their level values read as a measure of the level in the tank.
