  • Apparatus and method for measuring deposits inside a tube
    Patent number: 9593930
    Abstract: The present invention provides a probe apparatus and an associated method for measuring a magnetite deposit thickness, which apparatus and method is independent of the porosity and magnetic permeability of the magnetite deposit. The probe apparatus of this invention is an axial scanning and inside surface-following probe that can accurately and reliably measure the inside diameter of a tube. The probe apparatus of the present invention optionally comprises two modules: the first module is the surface-following module and the second module is a conventional eddy current probe.
