diameter. The 9.0" (the smallest) extension exists so that in
larger pipe sizes, where large variations in circumference can
occur, you can use one or two of these extensions to take up or
remove slack, to bring the scissors mechanism into a position
where it can be effectively tightened.
Mounting ring kits are available for different pipe sizes. A kit is
also available for partial pipe applications (see your Isco
Mounting Rings Installation and Operation Guide). For a listing
of part numbers and ordering information, see Appendix A.
To prevent debris from catching on the cable, it is important to
attach the cable to the mounting ring so it offers as little resis-
tance to the flow as possible. Attach the sensor cable to the down-
stream edge of the ring, using the self-locking plastic ties
supplied with the ring. Place the ties through the holes in the
edge of the mounting ring and then lock them around the cable.

Tightening the scissors assembly expands the ring to
press firmly against the pipe wall, securing the ring.
