Mounting the Monitor to the Manhole
Wall
If the project will involve measuring flow over a long period of
time, consider mounting the monitor permanently to the manhole
wall. Using a monitor mounting bracket/flange (ADS p/n I40-
0009), you can hang the monitor more securely and out of the way
to allow use of the rungs.
Mount the monitor handle to the manhole wall as follows:
1. Determine the appropriate location to mount the monitor
handle to the manhole wall. Consider the following when
selecting the proper location:
‰ Select a location that will allow you to remove the monitor
easily during service visits using the mounting bracket
(extension handle).
‰ Select a location that provides only a minimal potential for
the monitor to experience surcharge conditions.
‰ Select a location that will prevent the manhole lid from
potentially damaging the monitor during removal or when
rotating in the opening.
‰ Select a location that will allow personnel to enter/exit the
manhole without removing monitor.
2. Hold the top end of the mounting bracket against the manhole
wall, and mark the location for the mounting hole through the
keyhole in the bracket.
3. Drill a hole approximately 3 inches (75 mm) deep at the mark,
and install a 3/8-inch x 3-inch. (10-mm x 75-mm) anchor bolt
in the hole.
Note: Make sure all anchor bolts, studs, nuts, and
washers used in mounting the monitor are stainless steel.
