Apr\u00e8s avoir \u00e9t\u00e9 r\u00e9fl\u00e9chis par un liquide ou un autre milieu solide, les signaux reviennent vers la sonde et sont capt\u00e9s par celle-ci. La mesure de niveau est obtenue en mesurant le d\u00e9calage temporel entre l'\u00e9mission et la r\u00e9ception des ondes ultrasoniques. La relation entre la distance de transmission ultrasonique (L), la vitesse du son (v) et le temps de transmission ultrasonique (t) peut \u00eatre exprim\u00e9e par la formule suivante :<\/p>\n<p><strong><b>La formule de calcul de base pour la mesure de distance par ultrasons est la suivante : L = (v \u00d7 t) \/ 2<\/b><\/strong><\/p>\n<p>L : Distance entre la sonde \u00e0 ultrasons et la surface du mat\u00e9riau mesur\u00e9.

La coordination des tests dans ces diff\u00e9rentes directions permet au capteur d'assurer les fonctions d'\u00e9vitement d'obstacles sous-marins et de mesure de distance sous-marine.
