Abstract

Procédé pour déterminer le niveau d'eau dans une cavité allongée comprenant une émission d'un signal alternatif dans la cavité, variation de la fréquence de ce signal de manière à obtenir une réponse spécifique de la cavité, détection de cette réponse et comparaison du signal de sortie avec le signal de réponse. De préférence, la forme de la réponse est un signal de réponse réfléchie par la surface de l'eau. La fréquence de sortie peut être variée continuellement pour établir un substantiel état de différence de fréquence entre le signal d'entrée et le signal de sortie.
