Abstract

Méthode et système de détermination d’un niveau d’un liquide dans un récipient et/ou un conduit, notamment un carburant dans un réservoir d’un aéronef Un aspect de l’invention concerne une méthode de détermination d’un niveau de liquide dans un récipient et/ou un conduit (1), par exemple un réservoir, comprenant au moins un premier et un deuxième capteurs (11) positionnés respectivement au-dessus et en-dessous du niveau de liquide (5), le niveau du liquide étant déterminé à partir des vitesses de propagation d’un premier et d’un deuxième modes de propagation et d’un temps de propagation d’une onde élastique guidée se propageant dans la paroi du récipient ou du conduit selon le premier mode au-dessus du niveau de liquide (5) et selon le deuxième mode en-dessous du niveau de liquide (5). Figure à publier avec l’abrégé : Figure 1Method and system for determining the level of a liquid in a container and/or conduit, in particular fuel in an aircraft tank. One aspect of the invention relates to a method for determining the level of a liquid in a container and/or conduit (1), for example a tank, comprising at least a first and a second sensor (11) positioned respectively above and below the liquid level (5), the liquid level being determined from the propagation speeds of a first and a second propagation mode and a propagation time of a guided elastic wave propagating in the wall of the container or conduit according to the first mode above the liquid level (5) and according to the second mode below the liquid level (5). Figure to be published with the abstract: Figure 1
