Introduction 1-5
Telemetry
Wireless communication is available to the TRITON+ monitor
through an antenna and internal UMTS/HSPA+/GSM modem. The
antenna through which wireless communication occurs may be
located either inside or outside the manhole; however, ADS
recommends installing the antenna outside the manhole to maximize
signal strength.
Many antennas are available to mitigate signal strength issues.
While ADS offers two proven antenna options, customers also may
obtain their own antennas to accommodate specific project needs or
requirements. However, when assessing a third-party antenna,
please consult an ADS or IETG, as applicable, representative prior
to installing the antenna to verify the antenna can adequately
support monitor communications.
Connecting the TRITON+ to the Telog RTU (Model Ru-33) also
supports wireless communication via the Telog “passthrough”
mode. The Telog is mounted next to the TRITON+ in the
hazardous area and connected to the monitor using the Triton-Telog
Comm Cable (ADS p/n 8000-0054-01). However, please note that,
because the Telog unit does not possess IS certification, the
installation will not be considered intrinsically safe if the Telog unit
is installed in the manhole with the monitor.
Installation and IS Considerations
When installing the TRITON+ flow monitor, carefully follow any
local regulations for the installation of IS equipment. For example,
many clients only allow the use of special hazardous area tools
(flashlights, radios, etc.) in manholes. Some clients will not allow
the use of an electric drill, either battery-powered or AC-powered,
in a manhole. In this case, air (i.e., pneumatic) tools must be used.
When in doubt as to the applicable regulations, check with the client
or the client’s designated safety representative.
