Abstract

L'invention concerne un procédé et un moyen de détermination de la pression (1) d'un fluide (3) placé dans un conduit tubulaire (2). Dans une étape de déformation (101), le conduit tubulaire (2) est déformé par la pression (1). Dans au moins une étape de détection (102a ; 102b ; 102c ; 102d), une zone (4a; 4b; 4c; 4d) du côté extérieur du conduit tubulaire (2) est détectée optiquement par une caméra numérique (6a; 6b; 6c; 6d). Dans au moins une étape d'analyse (103a ; 103b ; 103c ; 3d), une analyse optique de la déformation d'une zone détectée (4a ; 4b ; 4c ; 4d) est effectuée et, dans une étape de calcul (104), la pression (1) du fluide (3) est calculée à partir de l'au moins une analyse optique de la déformation. L'invention concerne également un dispositif de mesure de pression correspondant (13).
