1-4 IETG FlowHawk Manual
Power
The FlowHawk flow monitor can be powered by an internal 12-volt
IS battery pack (p/n 8000-0043) or an external DC power source
through an external modem unit (EMU, p/n 3800-0148) or
EMU/multiplexer (EMUX, p/n 106226E)).
Telemetry
Wireless communication is available for the FlowHawk monitor via
connection to an IS quad-band GSM/GPRS module (p/n 8000-
0052), an EMU (p/n 3800-0148), or an EMUX (p/n 106226E).
Connecting the FlowHawk to the Telog RTU (Model Ru-33) also
supports wireless communication via the Telog “passthrough”
mode.
The GSM module is certified for installation and operation in the
hazardous area and receives power from the FlowHawk. The
antenna may be located either inside or outside the manhole;
however, IETG recommends installing the antenna outside the
manhole to maximize signal strength. Several antenna models are
available to mitigate signal strength issues.
The EMU is mounted outside the hazardous area and receives
power from an external DC power source supplied by the user. It is
delivered with the antenna installed on the inside of the EMU
enclosure. However, the antenna may require installation outside
the EMU if the material and/or construction of the enclosure and/or
housing in which the EMU enclosure is installed impedes the signal
from the wireless provider.
The EMUX is mounted outside the hazardous area and receives
power from an external DC power source supplied by the user. It is
delivered without an antenna; therefore, an antenna must be
attached to the EMUX. However, it may require installation outside
the enclosure in which the EMUX is installed if the material and
construction of the enclosure impedes the signal from the wireless
provider.
The Telog Ru-33 is mounted next to the FlowHawk in the
hazardous area and connected to the monitor using the Triton-Telog
Comm Cable (p/n 8000-0054-01). However, please note that,
