Sensor Installation and
Connection
The ADS TRITON+
designed for monitoring flow in sanitary, storm, and combined
sewers. The monitor mounts to the manhole rim or wall slightly
below the manhole cover or to a rung in the manhole.
A sewer system's hydraulics are much more stable and uniform in
the incoming pipe than in the manhole invert or outgoing pipe.
Therefore, the sensors mount to a stainless steel expandable ring or
stainless steel bands installed in the sewer pipe a short distance
upstream from the manhole invert. Installing the sensors upstream
minimizes the hydraulic effects and erroneous data readings caused
by foamy waters, waves in the flow, sewer noise, non-laminar flow,
and obstructions in the manhole.
Following is the basic procedure for installing the TRITON+
monitor and sensors at a location:
Investigate the Site Characteristics These characteristics
include pipe size and shape, silt level, flow depth, and
hydraulic conditions.
Prepare the Equipment for Installation The monitor,
communication system, and sensors must be prepared and
initialized for installation (See Chapters 3 and 4 for
communication and initial monitor setup).
