2-2 ADS TRITON+ Manual 
The TRITON+ monitor and sensors are primar ily designed for 
monitoring flow in sanitary and storm sewers.  The monitor mounts 
to the manhole rim or wall slightly below the manhole c over or to a 
rung on t he ladder; the sensors typically attach to a ring or band 
installed in the sewer pipe a sho r t distance upstream from the 
manhole invert.  The TRITON+ monitor can support up to two 
sensors at one or two separate loc a tions in the pipe. T he se sensors 
display excep tional durability and accuracy, even under harsh and 
turb ulent flow monitoring conditions.

Communication between the monitor and the user’s office or field 
computer can o ccur over TCP/IP (remote, wireless communication) 
or a USB serial interface cable (on-site communication). 
The TRITON+ is powered by a 12-volt IS battery p ack or through 
external power. Externally-powered units receive power from an 
independent source through an intermediate ExPAC (external power  
and c ommunicat ions unit), XBUS
™
, (external Modbus interface 
unit), or an XIO
™
 (external input/output) device. 
The ExPAC and XBUS also serve as Modbus interfaces to provide 
real-time data from the monitor to a SCADA (supervisory control
