ABSTRACT:
A method and apparatus determines a quantity of liquid in a tank when at least one liquid sensor is inoperative. In a first embodiment, a plurality of tables are stored in memory which are grouped by identities of the possible inoperative sensor or sensors. One group of tables is selected based on the identified inoperative sensor or sensors. Then, that one group of tables is accessed, and the quantity of liquid in the tank is calculated based on the readings of the operative sensors. In a second embodiment, a first plurality of tables stores quantity readings for each sensor as if all sensors are operable. A second plurality of tables includes one table for each possible configuration of inoperative sensor or sensors. When the inoperative sensor or sensors are identified, one particular table in the second plurality is accessed and a quantity amount is then added to the liquid quantities determined from the first plurality of tables to provide a total liquid quantity in the tank. Preferably, all tables are loaded with liquid quantity values based upon studies emulating a variety of tank and liquid positional attitude.
