Introduction
The IETG Intrinsically-Safe FlowHawk™ flow monitor (powered by
®
) measures open channel flow in sanitary sewers, storm
ADS
sewers, combined sewers, and other environments to assist
municipalities and other industry in address ing the following issues:
Planning sewer systems (sizing and rehabilitation)
Reducing infiltration and inflow (I/I)
Monitoring combined sewer overflows (CSOs)
Detecting and monitoring surcharges
1-1
Managing inter-agency billing
Monitoring sewage handling facilities (wastewater treatment
plants and pump stations)
The battery- or externally-powered FlowHawk monitor provides
exceptional accuracy and reliability in measuring open-channel flow
depth and velocity to determine flow rate (quantity) in pipes. This
flow data is the essential element required to successfully perform
investigative, analytical, and reporting activities.
This manual offers detailed instructions on installing, maintaining,
and troubleshooting the FlowHawk flow monitor, sensors, and
communication hardware.
1-2 IETG FlowHawk Manual
Intrinsic Safety
Intrinsic safety is an electronic hardware protection concept that
ensures there a re no conditions under which the equipment can
operate that could cause a release of energy sufficient to ignite a
hazardous gas or dust mixture. Devices that meet the low power,
current-limited design criteria are deemed Intrinsically Safe (IS).
Special design, testing, quality, and inspection rules apply to
manufacturers and users of IS equipment due to the critical nature
of their deplo yment in hazardous areas. Areas where hazardous
conditions can be expected to be present on a constant basis are
classified (rated) as Class I, Division 1 or Zone 0.
The FlowHawk flow monitor (Models 8000-FHK and 8000-FHK60C) is certified to ATEX (Atmosphere Explosibles) standards in
Europe and is certified for use in all classified (hazardous) sanitary
sewer and industrial hazardous areas. Many res t-of world countries
accept ATEX certification in lieu of their country-specific
requirements. It is the customer’s responsibil ity to ensure that
the certification(s) provided for the IETG equipment meets the
applicable regulatory requirements.
Note: FlowHawk models include only the 8000-FHK and
8000-FHK-60C.
FlowHawk System Certification
The FlowHawk unit and associated telemetry equipment are
certified for use only with approved sensors, communication cables,
and telemetry equipment. Connection of any non-approved devices
could result in unsafe operation and will immediately void the
warranty and IS certification.
Note: Connecting the Te l og® Ru-33 to the IETG
FlowHawk is an approved application and, therefore, will
not void the Fl owHawk warranty. However, because the
Introduction 1-3
Telog unit is not IS certified, the installation will not be
considered intrinsically safe if the Ru-33 is installed in the
manhole with the monitor.
Sensors
The FlowHawk monitor supports several approved IS sensors that
vary in measurement methodology, red undancy, and other features.
The monitor is approved for accommodating up to two of the same
or different types of IS sensors. Following are the approved IS
sensors:
Peak Combo Sensor Performs upward ultrasonic depth,
pressure depth, and peak velocity measurement and mounts at
or near the bottom (or invert) of the pipe under the flow surface
(p/n 8K-CS4-05-35, 8K-CS4-15-35, or 8K-CS4-30-1H).
Surface Combo Sensor Performs downward ultrasonic
depth, surcharge pressure depth, surcharge peak velocity, and
surface velocity measurement and mounts at the top (or
soffit/crown) of the pipe above the flow (p/n 8K-CS5-V2-05-30
or 8K-CS5-V2-15-30).
Ultrasonic Depth Sen sor (ultrasonic and optional
pressure depth only) Performs downward ultrasonic depth
and pressure depth (optional) measurement and mounts at the
top (or soffit/crown) of the pipe above the flow (p/n 8K-CS3V0-00-30, 8K-CS3-V0-05-30, or 8K-CS3-V0-15-30).
Slimline Peak Combo Sensor Performs upward ultrasonic
depth and peak velocity measurement and mounts at or near the
bottom of the pipe under the flow surface (p/n 8K-CS4-35).
Extension cables are available for these sensors in lengths up to 91
meters (300 ft).
Note: Detailed descriptions and specifications for the
sensors are available in Chapter 2, System Overview, and
Appendix A, Specifications.
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 wirel ess 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 is s ues.
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 imped es 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 r e quire 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,
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.
Installati on a nd IS Considerations
When installing the FlowHawk 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. Und er these conditions, use air (pneumatic) tools.
When in doubt as to the applicable regulations, check with the client
or the client’s designated safety representative.
Special Conditi ons f or Safe Use
During the ATEX /IECEx approval process, certain conditions are
set forth that must be observed when using the certified equipment.
These “Special Conditions for Safe Use” can be found in the body
of each ATEX Certification (referenced in this manual), as well as
on a page attached to the Declaration of Conformity. A summar y of
these Safe Use Instructions is as follows:
Introduction 1-5
• The Models 8000-FHK and 8000-FHK-60C shall use only the
12-volt IS Battery Pack (p/n 8000-0043) for internal power.
• The Models 8000-FHK and 8000-FHK-60C shall be used in
the hazardous area only when fully assembled. Do not perform
any maintenance of internal parts, replacement o f battery packs,
or replacement of fuses unless the unit is located in a safe area.
• Only approved sensors shall be connected to the Models 8000-
FHK and 8000-FHK-60C: sensor types 8K-CS1, 8K-CS3, 8KCS4, and 8K-CS5.
1-6 IETG FlowHawk Manual
Note: The 8K-CS1 is no longer available; however, IETG
will continue to provide support for this sensor.
• As aluminum is used at the acce ssib le surface of this unit, in the
event of rare incidents, ignition sources due to impact and
friction sparks may occur. This shall be considered when it is
being installed, particularly in locations that require equipment
with a Group II Ga level of protection.
• The only communication devices that may be connected to the
COMM conne ctor on the FlowHawk are the GSM Wireless
Module (p/n 8000-0052), the EMU/EMUX Communication
Cable (p/n 106227B), and the Direct Connect Interface (p/n
8000-0054)
Note: The Triton-Telog Comm Cable (p/n 8000-0054-01)
also may be connected to the COMM connector on the
FlowHawk to provide communication between the Telog
Ru-33 and the monitor. However, since the Ru-33 is not
certified for IS operation, an installation involving a
connection between these units will not be considered
intrinsically safe, unless the Telog unit is installed outside
the hazardous area.
• Never rub any plastic parts (specifically, the ABS plastic
connector potting boots and the Peak Combo Sensor and
Slimline Peak Combo Sensor housings) with a dry cloth. This
could result in the buildup of dangerous s t atic charges.
• Parts of the enclosure may be non-conducting and may generate
an ignition-capable level of electrostatic charge under certain
extreme conditions. Therefore, do not install this equipment in
a location where it may be subject to external conditions (such
as high-pressure steam or dust) that may cause a buildup of
electrostatic charge on non-conducting surfaces.
Maintenance Restrictions
As mentioned earlier, all FlowHawk flow monitors are
manufactured to meet IS standards. The monitor’s IS certification
can be voided instantly if proper maintenance and service
procedures are not followed. IETG must restrict certain
maintenance tasks to IETG IS-certified technicians.
IETG-certified technicians carefully inspect and document their
repairs of IS monitors. This inspection and documentation process
provides legal protection should the monitor's performance or safety
be in question.
If you experience trouble with this equipment, please refer to this
manual for troub l eshooting guidelines. The following maintenance
procedures may be performed in the field, but they must be
performed as described in this manual:
Install and swap monitor
Install and swap sensors
Install and swap battery pack
Introduction 1-7
Swap fuses in power regulator in monitor
Install and swap GSM wireless module

Note: The certifications included in this chapter identify
the FlowHawk, IS GSM Module, combo sensors, and
Direct Connect Interface as products of ADS. The
FlowHawk and its communication modules and sensors are
designed specifically for IETG by ADS.
Changes or Modifications
Changes or modifications to the FlowHawk flow monitor not
expressly approved by the party responsible for compliance will
void the IS certification.
Personnel performing installation of the FlowHawk flow monitor
should carefully follow the guidelines contained in this manual
when installing and maintaini ng the monitor. Failure to strictly
adhere to these guidelines can result in personal injury and can
cause damage to the monitor, which would invalidate its warranty.
The FlowHawk flow monitor is designed to be installed in
combined and sanitary sewer lines and manholes. This installation
work is inherently dangerous. All applicable safety guidelines
1-10 IETG FlowHawk Manual
should be followed and carried out by at least two fully trained and

Note: The Telog R u-33 can be connected to the COMM
port on the FlowHawk monitor using the Telog-Triton
Comm Cable (p/n 8000-0054-01). However, this
configuration has not been included on thi s drawing
because the Telog unit is not certified for IS opera tion.
Therefore, an installation involving this configuration will
be considered intrinsically safe, unless the Ru-33 is
installed outside the hazardous area.
1-12 IETG FlowHawk Manual
GSM/GPRS Modem Information
Wireless telemetry is provided via attachment of the GSM Module
to the FlowHawk monitor. The GSM Module contains a thirdparty, R&TTE-CE-certified, commercial GSM/GPRS modem.
Integration of the modem into the GSM Module was performed in
accordance with guidelines set forth in the third party’s Integration
Manual in order to maintain the FCC approval.
Use of the modem, as installed in the GSM Module, is considered a
Mobile wireless application, meaning the module is capable of
being moved between locations. However, it is NOT considered a
Portable device, which indicates it is used in close proximity to a
user’s body (like a handset). Users of the GSM Module must
maintain a distance from the antenna of at least 200 mm (7.87 in)
when the unit is operational.
Users cannot provide their own antennas due to strict limitations on
antenna gains and other variables that may produce a dangerous RF
condition and violate IS and European safety requirements. Only
antennas provided by IETG for use with the GSM Module may be
used.
Compliance with applicable European Directives is demonstrated
through the following marking:
CE 0889
This marking indicates that the Enfora GSM0308 OEM module is
entirely encapsulated to meet IS requirements. The o nly useraccessible part of the modem is the SIM card carrier.
