Installing the Ring in the Pipe
The ring must fit securely in the pipe with the sensors properly
positioned to ensure the most accurate monitoring results. Install the
ring in the pipe in the following way:
1. Examine the pipe for possible obstructions to the flow or issues
that may inhibit proper ring installation.
2. Adjust the ring size to slightly less than the pipe diameter
before placing the ring in the pipe by turning the spreader
mechanism adjustment nut clockwise.
3. Place the ring in the input pipe at least 12 inches upstream from
the manhole or edge of the pipe with the sensors facing
upstream toward the oncoming flow. It must be located far
enough upstream from the manhole to minimize the effect of
the draw-down caused by a possible drop in the manhole invert.
