1. A device for monitoring internal pipe deposit accumulation, comprising:
a pipe segment having opposed first and second open ends;
at least one valve releasably sealing at least one of the first and second open ends of the pipe segment;
a first electrode comprising an electrically conductive cylindrical shell mounted on and surrounding a portion of an external surface of the pipe segment;
a second electrode comprising an electrically conductive rod mounted within an interior of the pipe segment, the second electrode extending axially and being positioned coaxially with respect to the pipe segment;
an electrical power source electrically connected across the first and second electrodes to form a cylindrical capacitor; and
means for monitoring changes in capacitance of the cylindrical capacitor, whereby changes in the capacitance are representative of changes in a thickness of a deposit accumulating on an internal surface of the pipe segment.
