Abstract

Un procédé de caractérisation d’un fluide dans un circuit comprenant : une première étape de mesure (E1) d’une première température et d’une première permittivité à un premier instant et à une première position du circuit, formant un premier couple de mesure (K1), une première étape de comparaison (E2) dudit premier couple (K1) à une base de données (12), de manière à déterminer une première sélection de fluides (S1), une deuxième étape de mesure (E3) d’une deuxième température et d’une deuxième permittivité à un deuxième instant et à une deuxième position du circuit, formant un deuxième couple de mesure (K2), une deuxième étape de comparaison (E4) dudit deuxième couple (K2) à ladite base (12), de manière à déterminer une deuxième sélection de fluides (S2), et une étape d’identification (E5) du fluide par intersection de la première et de la deuxième sélection (S1, S2).
