Abstract
The present invention relates to apparatus for monitoring fluid flow in a pipe using electromagnetic velocity tomography (EVT). The apparatus generates a magnetic field within a pipe and when electrically conducting fluid, such as an aqueous phase, flowing along the pipe passes through the magnetic field, flow induced voltages are generated by magnetic induction which are detected by electrodes. The signals at the electrodes can be processed to produce images of the flow velocity profile in the pipe. The flow may be a multiphase flow which comprises fluids, and may comprise a mixture of liquids, or one or more liquids in a mixture with solids and/or gases. This invention may provide a multiphase flow metering apparatus which has a number of applications, in particular within the oil and gas exploration and production industry.
