Development of a Corrosions-Sensor for Multiphase Transportation Systems

The conference paper will describe the development of a new, two electrode corrosion sensor for the use in multiphase transportation systems. A critical overview will be given as to the current state of the art of commercial corrosion sensors, pros and cons will be discussed. A short introduction to sequence dependent and sequence independent signal processing will be given to show how different corrosion types such as general corrosion, pitting corrosion and crevice corrosion can be identified. The principle design of the sensor will be presented in two versions, as well as the flow loop used for testing and the monitoring software for the data analysis.
