Abstract

L'invention concerne un débitmètre volumique et l'utilisation d'un débitmètre volumique pour déterminer le débit volumique d'un fluide. Le débitmètre volumique présente un capteur de débit et un dispositif d'échantillonnage de signal. Le capteur de débit présente un élément d'étanchéité radialement en saillie, l'élément d'étanchéité présentant par rapport à un sens d'écoulement désigné une longueur de distance de montage. Le capteur de débit se situe au moins en partie à l'extérieur de la longueur de distance de montage par rapport au sens d'écoulement. Contrairement à l'état de la technique, la mesure du débit volumique n'est pas intégrée dans un système de mesure assemblé, mais, de manière peu encombrante, directement dans la conduite présente en un point de séparation inhérent au système, dans tous les cas présents.
