Abstract
A flush mounted probe assembly for monitoring the corrosion environment within a thin boundary liquid film disposed along the interior sidewall surface of a pipeline carrying fluids. The assembly comprises a probe received within a nipple secured to the pipeline. An end portion of the probe projects snugly into the opening and terminates in an end face residing substantially in alignment with the interior sidewall surface. The probe is releasably secured within the nipple and sealed thereto against fluid leakage. The probe's end face has an imperforate smooth surface which is contoured and dimensioned within the opening in the pipeline to substantially conform to the interior sidewall surface without a surface discontinuity in the pipeline to disrupt the thin boundary liquid film. The probe carries electrodes having smooth exposed surfaces merging into the end face. Electrical conductors connect with the electrodes in the probe and extend in electrical isolation to an external circuit connection. In a preferred embodiment, the end portion is circular with a planar end face containing annular metal electrodes.
