Abstract

L'invention concerne un système pour mesurer le débit de phases multiples. Le système est constitué d'un segment d'un canal d'écoulement (1) à section transversale de forme quelconque dans lequel un corps de canal (2) est encastré. Ce corps de canal (2) est percé par une pluralité de canaux (3) à petit diamètre hydraulique s'étendant dans le sens d'écoulement. La largeur des canaux est à choisir de telle manière qu'un courant monophasé ou un courant piston se forme dans les canaux aux vitesses de mélange attendues. Les informations nécessaires pour une telle conception ressortent mieux d'une carte d'écoulement correspondante. La disposition des canaux (3) en coupe transversale peut être régulière, par exemple sous la forme d'une grille quadratique, ou peut être irrégulière. Dans chacun des canaux (3) se trouvent au moins deux capteurs de phase (4) qui sont disposés l'un derrière l'autre en direction axiale et sont en mesure d'identifier avec des taux de détection élevés la phase de matière du mélange (l'indicateur de phase) entourant le capteur de phase (4) concerné. Les capteurs de phase (4) peuvent se trouvent à l'intérieur des canaux (3) sur leur surface intérieure ou à l'entrée et à la sortie des canaux (3) sur le corps de canal (2). Les capteurs de phase (4) peuvent fonctionner selon un principe optique (réflexion, transmission), électrique (capacitif, inductif, conducteur, électromagnétique), acoustique (écho sonore, transmission sonore) électromécanique (ondes de surface, résonance oscillatoire), radiométrique ou selon un autre principe de mesure.
