Abstract

A remote field eddy current, RFEC, system for detecting an azimuth location of a defect in a pipe includes a holder extending along a longitudinal axis X and shaped to flow through the pipe, a magnetic field generator located within the holder and configured to generate a first magnetic field B, a 3-axis fluxgate magnetometer located within the holder, at a given distance away from the transmitter, along the longitudinal axis X, wherein the fluxgate magnetometer is configured to measure a second magnetic field B, which is a result of the first magnetic field Binteracting with the defect in the pipe, and a controller located within the holder and configured to receive a value of the second magnetic field B and to determine an azimuth of the defect in the pipe by interpreting radial components of the measured field, and an extent of the defect based on the second magnetic field B.
