Abstract
A method for fuel quantity gauging that measures the quantity of liquid fuel in a fuel tank. The method includes the following steps performed while fuel is flowing out of the fuel tank: changing a volume of gas in the fuel tank (e.g., by injecting or venting gas) during a time interval; measuring a rate of change of the volume of gas in the fuel tank during the time interval; measuring a rate of flow of fuel out of the fuel tank during the time interval; measuring a first pressure and a first temperature of the gas in the fuel tank at the start of the time interval; measuring a second pressure and a second temperature of the gas in the fuel tank at the end of the time interval; and calculating a quantity of fuel in the fuel tank based on the acquired measurement data.
