METHOD AND APPARATUS FOR MONITORING OF THE MULTIPHASE FLOW IN A PIPE

摘要

A monitoring apparatus for monitoring a multiphase flow in a pipe using magnetic induction tomography, the apparatus comprising: at least one annular array of elements disposed around a pipe, each element being adapted to transmit a magnetic field when energized by an input electrical signal and/or to receive a magnetically-induced electrical field and generate an output electrical signal, and at least one screening device for screening at least one of the elements of at least one of the annular arrays from an interfering magnetic field emitted from at least one other element. Also disclosed is a method of monitoring a multiphase flow in a pipe using magnetic induction tomography.
