CA 2378059

A pipe (16) having a produced fluid (18) (liquid and/or gas) and at least two acoustic pressure sensors (20-24), is provided with a cylindrical sleeve (30) attached to the pipe (16) at two locations around a sensing region where the sensors (20-24) are located, the sleeve forming a closed cavity (32) filled with a fluid (or material) having an acoustic impedance (pc2) that is much less than the acoustic impedance (pc1) of the produced fluid (18) in the pipe (16) (i.e., pc2<<pc1), which causes the sleeve (20) to isolate the acoustic sensors (20, 22, 24) from being affected by acoustic properties of the cavity (32) and the acoustic properties outside the pipe (16). For most effective acoustic, the cavity (32) may be evacuated.

L'invention concerne un conduit (16) contenant un fluide produit (18) (liquide et/ou gaz) et au moins deux détecteurs acoustiques de pression (20, 24), ledit conduit étant pourvu d'une enveloppe cylindrique (30) fixée sur le conduit (16) à deux emplacements autour d'une zone de détection où se trouvent les détecteurs (20-24), l'enveloppe formant une cavité fermée (32) remplie avec un fluide (ou matière) à impédance acoustique ( rho c2) qui est nettement inférieure à celle ( rho c1) du fluide produit (18) dans le conduit (16) (i.e., rho c2<< rho c1), ce qui permet à l'enveloppe (20) d'isoler les détecteurs acoustiques (20, 22, 24) des modifications engendrées par les propriétés acoustiques de la cavité (32) et par celles provenant de l'extérieur du conduit. Pour obtenir une meilleure acoustique, la cavité (32) peut être évacuée.
