Abstract
A non-intrusive device for attachment to a pipe or vessel through which a fluid flows for monitoring the accumulation of deposits on the interior surface of the pipe or vessel. The device comprises a tubular member having an internal cross-sectional configuration substantially matching that of the pipe or vessel. Additionally, the tubular member is made of an electrically insulating material and having associated therewith three spaced electrodes for monitoring the change of dielectric constant within the pipe or vessel.
