摘要： Liquid gauging system for liquid in a container includes a plurality of sensors; each of the sensors measuring a respective parameter of the liquid in the container and producing a sensor output related to its measured parameter; there being at least two sensors that measure different parameters of the liquid; and a processor that receives the sensor outputs and determines, based on the sensor outputs, a quantity of the liquid in the container; the processor determining the quantity by executing at least one sensor fusion algorithm that is based on a set of relationships between the measured parameters and the quantity. The gauging system can also include a data fusion process for determining quantity based on a plurality of quantity measurements.

摘要： A method for determining an optimized solution of positions for N liquid surface sensors used to gauge quantity of liquid in the container, comprising the steps of:a) defining geometric limits of the container in terms of coordinates of a three axis (x,y,z) reference coordinate system assigned to the container;b) defining a chromosome structure for an individual, wherein said chromosome structure identifies a solution in terms of position data of the N sensors;c) determining a population of individuals wherein each individual in said population is a possible solution within said geometric limits; each individual having a respective chromosome; andd) executing a genetic algorithm on said population to identify a solution that meets a performance criteria as measured by a predetermined cost function.
