Abstract

L'invention concerne un procédé de mesure de courants de fluide selon lequel des impulsions ultrasoniques sont émises dans le fluide dans des directions changeantes au moyen d'une unité ultrasonique à commande de phase et les réponses aux impulsions provenant de différentes directions sont évaluées pour déterminer un courant de fluide. Il est prévu qu'à partir des impulsions ultrasoniques, en tenant compte de la section transversale du lit de fluide guidant un liquide et en tenant compte de la paroi du lit de fluide et/ou de la présence ou de l'absence de sédiments, le débit total passant par cette section transversale soit déterminé par corrélation croisée à partir des vitesses de courant pour des volumes donnés se trouvant dans différentes directions.
