Method for simulating the gauging of a liquid tank
First Claim
1. A method for generating a gauging curve for a hollow body configured to contain a liquid, said curve including a set of measurement points for a liquid level inside the hollow body, said curve approaching an optimum gauging curve, said method comprising:
- for several different partial filling volumes of said hollow body, calculating an average center of mass of a corresponding free liquid surface for various inclinations of the hollow body, in terms of both amplitude and direction; and
generating a gauging curve that passes substantially through each of said average centers of mass, in whichthe hollow body is a fuel tank comprising a fuel extraction pump comprising an extraction point and in which the gauging curve includes a starting point close to or coincident with this extraction point.

Abstract
A method for generating a gauging curve for a hollow body containing a liquid. The curve including a set of measurement points for a liquid level inside the hollow body, and the curve approaching an optimum gauging curve. The method includes, for several different partial filling volumes of the hollow body, calculating an average center of mass of a corresponding free liquid surface for various inclinations of the hollow body, in terms of both amplitude and direction. The method further includes generating a gauging curve that passes substantially through each of the average centers of mass.

-
for several different partial filling volumes of said hollow body, calculating an average center of mass of a corresponding free liquid surface for various inclinations of the hollow body, in terms of both amplitude and direction; generating a gauging curve that passes substantially through each of said average centers of mass; selecting a gauge with given location, shape and orientation; calculating a calibration curve for a coupling of the gauge and the hollow body; simulating a deformation of the hollow body on a virtual model thereof for at least one ageing period; calculating a gauging error associated with this ageing period; and verifying that said calculated gauging error does not exceed a predetermined maximum gauging error.
