Apparatus for monitoring of the multiphase flow in a pipe

A monitoring apparatus for monitoring a multiphase flow in a pipe using magnetic induction tomography, the apparatus comprising:

• a first coil mount assembly comprising a first attachment mechanism and a second attachment mechanism, the first coil mount assembly configured to support a plurality of planar faces, wherein each planar face extends parallel to a central longitudinal axis of the pipe, and wherein each planar face at least one electrical coil, wherein the at least one electrical coil comprises an electrically conductive wire to form a plurality of wire turns, and wherein the axis of the wire turns are perpendicular to the central longitudinal axis of the pipe;
• and
• a second coil mount assembly comprising a first attachment mechanism and a second attachment mechanism, the second coil mount assembly configured to support a plurality of planar faces, wherein each planar face extends parallel to a central longitudinal axis of the pipe, and wherein each planar face includes at least one electrical coil,
• wherein the first coil mount assembly and the second coil mount assembly are configured to have a plurality of indexed mounting positions on the pipe, wherein each indexed mounting position separates the first coil mount assembly from the second coil mount assembly by a specified distance along the central longitudinal axis of the pipe.
