Abstract
Apparatus for monitoring fluid flow in a pipe using electromagnetic velocity tomography An apparatus for monitoring a fluid flow in a pipe using electromagnetic velocity tomography (EVT), the apparatus comprising a pipe defining a flow conduit, a coil system comprising electrically conductive wires located externally of the flow conduit for generating composite magnetic fields within the flow conduit, a magnetic signal driving circuitry electrically connected to the coil system which is arranged to pass electrical current through the coil system thereby to transmit a magnetic field from the coil system into the flow conduit, a plurality of measurement electrodes located around the flow conduit for detecting voltages induced in an electrically conducting fluid flowing thorough the magnetic field, and a signal processing circuitry electrically connected to the plurality of measurement electrodes for receiving flow induced voltage signals from the electrodes, wherein the plurality of measurement electrodes is comprised in a flexible printed circuit board which is positioned circumferentially around the pipe, the printed circuit board comprising a first lamina, the first lamina compris…
