Abstract

L'invention concerne des moyens pour mesurer un niveau de fluide dans un réservoir, par exemple un niveau d'une solution aqueuse d'urée dans un réservoir pour pots catalytiques de moteurs à combustion. Les moyens de mesure comportent : • au moins un capteur comportant un élément capacitif couplé électriquement à un oscillateur configuré pour délivrer un signal Si dont la fréquence FiPAD est fonction de la capacité de l'élément capacitif ; ledit au moins un capteur étant destiné à être disposé à l'extérieur du réservoir, de sorte que la capacité de l'élément capacitif varie en fonction du niveau n du fluide, lorsque ledit niveau est compris entre un premier seuil hi-min et un deuxième seuil hi-max ; • un module de traitement, couplés audit au moins un capteur, et configurés pour déterminer le niveau n de fluide dans le réservoir en fonction de la fréquence du signal Si.
