Monitor and Sensor Installation 3-5
Assembling the Ring
The flow sensors mount to a stainless steel ring that is installed in
the pipe. Several different ring sizes exist, and each ring is
adjustable within about 3 inches to fit pipes of different diameters.
Assemble the ring in the following way:
Note: These instructions generally apply to overlapping
rings. However, the 8-, 10-, and 12-inch rings do not have
an overlapping section. Therefore, these non-overlapping
rings will require small modifications to the assembly
process. To assemble a non-overlapping ring, proceed
directly to step 4.
1. Insert the spreader mechanism screw through the hole in the
center of the ring stabilizer. Ensure that the head of the screw
fits into the countersunk hole.

2. Slide the open end of the ring (end without the welded metal
band) through the flanges in the ring stabilizer, making sure
the flanges face the outside of the ring and the spreader
mechanism screw faces the inside of the ring.
