Title
(EN) METHOD AND APPARATUS FOR MONITORING OF THE MULTIPHASE FLOW IN A PIPE
(FR) PROCÉDÉ ET APPAREIL DE SURVEILLANCE D'UN ÉCOULEMENT POLYPHASIQUE DANS UN TUYAU
Abstract
(EN)
A monitoring apparatus for monitoring a multiphase flow in a pipe using magnetic induction tomography, the apparatus comprising a pipe defining a flow conduit, at least one pair of first and second coils disposed on the pipe, wherein the first coil is adapted to transmit an electromagnetic field into the flow conduit when energized by an input electrical signal and the second coil is adapted to receive an electromagnetic field from the flow conduit and generate an output electrical signal, wherein each of the first and second coils comprises an electrically conductive element which is wound about a central axis to form a plurality of turns, wherein each turn is in a common plane so that the respective coil is planar and each turn is composed of a plurality of linear sections and the respective coil is polygonal in plan, the apparatus further comprising a controller for selectively switching alternating electrical current through the first coil to generate from the energized first coil a local electromagnetic field which is transmitted into the fluid conduit, and for receiving an induced alternating electrical current from the second coil which is generated from the local electromagnetic field. Also disclosed is a method of monitoring a multiphase flow in a pipe using magnetic induction tomography.

La présente invention concerne un appareil de surveillance permettant de surveiller un écoulement polyphasique dans un tuyau à l'aide d'une tomographie par induction magnétique, l'appareil comprenant un tuyau définissant un conduit d'écoulement, au moins une paire de première et seconde bobines disposées sur le tuyau, la première bobine étant conçue pour émettre un champ électromagnétique dans le conduit d'écoulement lorsqu'elle est excitée par un signal électrique d'entrée et la seconde bobine étant conçue pour recevoir un champ électromagnétique provenant du conduit d'écoulement et générer un signal électrique de sortie, les première et seconde bobines comprenant chacune un élément électroconducteur qui est enroulé autour d'un axe central pour former une pluralité de spires, chaque spire étant dans un plan commun pour que la bobine respective soit plane et chaque spire étant composée d'une pluralité de sections linéaires et la bobine respective étant polygonale dans le plan, l'appareil comprenant en outre un dispositif de commande servant à faire passer sélectivement un courant électrique alternatif à travers la première bobine pour générer à partir de la première bobine excitée un champ électromagnétique local qui est émis dans le conduit de fluide, et pour recevoir un courant électrique alternatif induit à partir de la seconde bobine qui est généré à partir du champ électromagnétique local. L'invention concerne également un procédé de surveillance d'un écoulement polyphasique dans un tuyau à l'aide d'une tomographie par induction magnétique.
