Abstract - A passive electrical topography system, which utilizes particle charge as a source, was developed. Two tomographic sensing methods, charge and displacement current, were applied. This system of eight electrode was settled three point in a cold riser and examined. Difference between obtained images by two sensing method correspond to internal solid circulation in riser.
