Abstract

La présente invention est du domaine de la mesure de débits au moyen d'un capteur dit à induction de vortex. Un capteur selon l'invention est caractérisé principalement en ce qu'il comprend un organe magnéto-sensible 19 logé dans une cavité 19a d'une partie avant formant obstacle et un élément de proximité 18 solidaire d'une partie arrière oscillante 15; plus particulièrement ledit élément de proximité est un élément permanent en forme de tige et ledit organe magnéto-sensible est soit une magnéto-résistance, soit un dispositif à effet Hall. Application à la mesure des débits, notamment des fluides corrosifs.
