In order to prevent the probe from contacting the bridle wall when replacing
displacers or installing in pipes, centering discs are available for the Rigid
Single, Flexible Single and Flexible Twin Lead probes. The disc is attached to
the end of the probe and thus keeps the probe centered in the bridle. The
discs are available in stainless steel and teflon (PTFE). See also “Mounting a
Centering Disc for Pipe Installations“ on page 3-20.
