The present invention is part of a liquid gaging system and comprises an apparatus for reducing error introduced by an incapacitated sensor. Included are a plurality of sensors, each sensor providing a liquid measurement signal relating to a liquid depth at a particular location in a tank. The invention also comprises apparatus for selectively monitoring the liquid measurement signal of each individual sensor, the apparatus for selectively monitoring being connected to the sensors. Also included is apparatus for identifying at least one sister sensor corresponding to each sensor. The invention further comprises apparatus for determining an estimated liquid depth corresponding to an incapacitated sensor by using the liquid measurement signal of at least one sister sensor corresponding to the incapacitated sensor. The apparatus for determining is connected to the apparatus for selectively measuring and the apparatus for identifying.

In a liquid gaging system wherein a value related to a liquid quantity in a tank is determined by the system based on signals from a plurality of sensors, the accuracy of the value being dependent upon the validity of the signals from the sensors, an apparatus for reducing error in the value introduced by an incapacitated sensor, comprising: the plurality of sensors, each sensor providing a liquid measurement signal relating to a liquid depth at a particular location in the tank; means for selectively monitoring the liquid measurement signal of each individual sensor, the means for selectively monitoring being connected to the sensors; means for identifying at least one sister sensor corresponding to each sensor; and means for determining an estimated liquid depth corresponding to the incapacitated sensor by using the liquid measurement signal of the at least one sister sensor corresponding to the incapacitated sensor and for determining the value based on the liquid measurement signals and the estimated liquid depth, the means for determining being connected to the means for selectively monitoring and the means for identifying; whereby the value has less error associated with it than if an invalid liquid measurement signal from the incapacitated sensor were used to determine the value.
