CHAPTER 2
System Overview
The ADS® FlowAlert monitor is a data logger and alarm system
that uses up to two devices to measure or detect fluid levels: a
pressure depth sensor and up to two float switches. The pressure
depth sensor is a gauge-type sensor provided by ADS for mounting
in the pipe or on the manhole or vessel wall. The float switch(es) is
suspended in such a way that it becomes buoyant and trips its
internal contact at a predetermined, fixed elevation.
The monitor receives the raw pressure depth data and float state
from the sensor and float, respectively, based on a defined time
interval. The float also can provide instantaneous notification when
changes in state occur. The monitor stores this data in memory and
can use the data to generate an alarm. The multiple depth devices
help enhance these alarming capabilities.
The monitor memory can store a little over 2 years of data logged at
a 15-minute sample rate. This data is available to the user for
collection, further processing, analysis, and reporting. These
reports can assist municipalities and other industry in planning
improvements and additions to sewer systems and providing
information for the overall management of the sewer system.
The FlowAlert monitor, pressure depth sensor, and float switch are
primarily designed for use in sanitary and storm sewers and pump
station wet wells. The monitor mounts to the manhole rim or wall
slightly below the manhole cover. The pressure depth sensor
typically attaches to a ring installed in the sewer pipe a short
distance upstream from the manhole invert at a location called a
2-2
ADS FlowAlert Manual
monitoring point. The float switch hangs suspended in the middle
of the manhole and is secured just below the manhole rim by its
cable. This equipment displays exceptional durability and accuracy,
even under harsh and turbulent flow monitoring conditions.
Typical FlowAlert system installation
Communication between the monitor and the user’s office or field
computer can occur over GPRS (remote, wireless communication),
a telephone line (remote, landline communication), or a direct
connection cable (on-site communication).
Special software called Profile® enables the user to configure and
communicate with the monitor for activation, data collection, and
diagnostic purposes. Configuration involves defining the location
information file (LIF) for storage in the user's local directory and
building the code and variables for the site. The LIF contains
information such as pipe characteristics, monitor identification,
selected devices, alarm/event notification settings, data log rate, and
other parameters necessary for measuring and monitoring the flow
depth both accurately and efficiently.
System Overview
2-3
Activation involves downloading the firmware (embedded software)
code and site-specific information from the LIF (stored in the user's
local directory or network drive) to the monitor. It also includes
initiating monitor activities such as taking sensor readings, logging
flow data, and managing event notification and alarming.
Profile also enables the user to process the flow data, generate
graphical and tabular reports, organize data in the user's local
directory, and maintain logs of communication between the monitor
and the user's PC.
Note: Refer to the Profile User's Guide (#950015**) for
more information.

Printed circuit board (PCB)
Digital Signal Processing
The Digital Signal Processor (DSP) contains the central processing
unit (CPU). As the source of all monitor activity, the processor is
responsible for all of the monitor's high-level functions, including
the following:

Scanning the sensor and float switch inputs to retrieve data for
processing and storage

Maintaining the monitor time and date

Performing power management

Transmitting the stored and current data to the user's PC

Initiating event and alarm notification
The DSP allocates portions of memory to firmware (permanently
stored software) and data storage. A seven-segment (SS) lightemitting diode (LED) located on the board indicates the current
monitor communication and operational activity. The DSP also
2-6
ADS FlowAlert Manual
includes the monitor clock, random access memory (RAM), and
Flash. The monitor uses RAM while taking readings and
processing the flow data. The RAM then downloads the data to
Flash, or non-volatile memory, which also stores the monitor
firmware and configuration information. Flash ensures the monitor
maintains the data during battery pack replacement or a power
failure.
Input Device Processing
The input component of the board controls the processing of the
pressure depth sensor and the float switch. It initiates pressure
depth sensor readings and requests for the float switch state. The
board also processes the solicited (and unsolicited) data received
and stores it in the monitor memory.
Communications
The communications component of the board provides multitasking/handling of all communications processes. It interfaces to a
landline or wireless modem (based on the model of FlowAlert), as
well as manages local serial communication requests. The
communications component also is responsible for gathering realtime information from the other components on the board.
Voltage Regulator
The voltage regulator regulates and distributes power supplied from
the battery pack to the analog, communications, and DSP
components on the board.
Communications
ADS offers two remote communication options for the FlowAlert
monitor. The first option involves wireless communication over the
cellular network using GPRS (General Packet Radio Service)
through the modem in the monitor. GPRS facilitates high-speed,
low-cost, efficient TCP/IP communication in areas with AT&T
System Overview
wireless coverage. The second option involves telephone
communication over land lines using the modem in the monitor.
Local communication with all FlowAlert monitors is available
through a direct serial cable connected to the DIRECT
COMM/EXT POWER port.
Connectors
Connectors located on top of the monitor receive the following
cabling and components:
Note: Connectors available depend on the FlowAlert
model. Refer to the appendices for specifics on different

Power
The ADS FlowAlert Monitor is powered by an internal 7.5 volt
alkaline battery pack (ADS p/n 6000-0004) mounted at the bottom
of the enclosure. This battery pack provides the power for
operating the monitor, handling communication, and sustaining the
monitor wake-up circuitry. The monitor measures the battery
voltages, and Profile provides a user-defined setting to ensure the
monitor signals a warning when the available power is low.
Battery voltage is logged during most communication sessions and
also is available on demand when performing diagnostics.

Flow Depth Devices
The FlowAlert monitor uses measurement devices to gather flow
depth data or status. The pressure depth sensor obtains static gauge
pressure data for use in determining the depth of the flow. The float
switch provides status (or state) information regarding its position
to indicate whether the depth of the flow has exceeded beyond or
fallen below a certain threshold.
Pressure Depth Sensor
The pressure depth sensor (ADS p/n 3704-0010/15/16 –
representing 5/15/30 psi pressure sensor ranges, respectively)
mounts to a stainless steel expandable ring or stainless steel band
installed in the pipe upstream from the manhole or to a small
stainless steel band secured to the manhole/wet well wall.
Pressure depth sensor
A sewer system's hydraulics are much more stable and uniform in
the incoming pipe than in the manhole invert or outgoing pipe.
Installing it upstream minimizes hydraulic effects and erroneous
data readings caused by flow waves and obstructions in the
manhole. Therefore, install the sensor in the incoming pipe (at or
near the bottom of the pipe) for accurate depth measurements.
2-10
ADS FlowAlert Manual
If accurate depth measurements are not necessary or applicable,
mount the sensor to the wall of the manhole or wet well.
The pressure depth sensor can measure depths greater than a full
pipe that might extend up into the manhole (i.e., surcharges). The
FlowAlert supports pressure sensors with ranges from 0-5 (11.5), 015 (34.5), and 0-30 PSI (69.0 ft).
The pressure depth sensor contains a differential pressure
transducer that transmits an output voltage corresponding to the
difference between the water pressure and the air pressure in the
sewer. It measures water pressure through a port on the underside
of the sensor and air pressure using an integral vent tube running to
the top of the manhole. The monitor calculates the depth of the
flow by reading the difference in pressures.
Float Switch
The float switch typically is anchored just below the manhole rim
and hangs suspended in the center of the manhole from its
supporting cable at an elevation designated in the project
requirements. It includes an integrated switch and weight system
that enables the float to change position (which activates a switch)
when the flow elevates to and recedes from a specific elevation in
the manhole. This elevation represents the point at which the state
of the switch changes. The FlowAlert receives notification from the
float whenever the change in state occurs.
System Overview
2-11
High and High-High float switches
When the float is suspended vertically above the fluid, the internal
switch remains in a closed state. If the depth level rises and
contacts the end of the float, the internal weight allows the float to
begin to pivot into a horizontal position. If the end of the float rises
slightly above this position (5 degrees above horizontal), the switch
transfers to an open state and communicates the change in state to
the FlowAlert monitor for logging and/or alarming purposes. When
the depth level recedes and the end of the float falls below the
switch threshold, the switch returns to a closed state once again.

3-1
CHAPTER 3
Pressure Depth Sensor and Float
Switch Installation
The ADS® FlowAlert monitor, pressure depth sensor, and float
switch are primarily designed for monitoring flow in sanitary,
combined, storm sewers, and pump station wet wells. The monitor
mounts to the manhole rim or wall slightly below the manhole
cover.
The pressure depth sensor can mount to a stainless steel, expandable
ring or a stainless steel band installed in the sewer pipe a short
distance upstream from the manhole invert. A sewer system’s
hydraulics are much more stable and uniform in the incoming pipe
than in the manhole invert or outgoing pipe. Installing the sensor
upstream minimizes the hydraulic effects and erroneous data
readings caused by conditions in the pipe and the manhole.
The pressure depth sensor also can mount to a short, stainless steel
strap secured to the wall of the manhole or wet well when flow
depth measurements in the pipe are not applicable or necessary.
The float switch hangs from its cable in the center of the manhole,
and the cable is secured just below the manhole rim. Hanging the
float in the center prevents it from contacting or becoming tangled
with other objects in the manhole that may keep it from pivoting
properly when the flow rises or recedes.

ADS FlowAlert Manual
Following are the basic steps for installing the FlowAlert monitor,
pressure depth sensor, and float switch at a location:

Investigate the Site Characteristics These characteristics
include pipe size and shape, silt level, flow depth, and manhole
depth, environment, and obstructions.

Install the Sensor The procedure varies based on the sensor
mounting location:
 In the Pipe This process primarily includes assembling
the ring (for standard installations) or preparing the band
(for special installations) to which the pressure depth
sensor attaches, securing the sensor cable to the ring or
band, and installing the ring or band in the pipe.
 In the Manhole/Wet Well This process primarily
involves attaching the pressure depth sensor to the
mounting strap and mounting the strap in the manhole/wet
well.

Secure and Connect the Cable This procedure involves
securing the pressure depth sensor cable from the ring, band, or
strap to the monitor location in the manhole.

Install the Float Switch in the Manhole This process
includes lowering the float switch to the proper elevation in the
manhole and then securing the float switch cable to the
appropriate location in the manhole.

Connect the Sensor and Float to the Monitor This
involves connecting the pressure depth sensor and float
switch(es) to the FlowAlert monitor.
Pressure Depth Sensor and Float Switch Installation 3-3
Typical FlowAlert flow monitor, sensor, and float installation
This chapter contains detailed instructions for properly installing a
pressure depth sensor and a float switch(es) in sanitary, storm, and
combined sewer lines; manholes; and pump station wet wells.
Note: Manhole and sewer system work involves confined
space entry and is inherently dangerous. Therefore,
installers and technicians must comply with all federal,
state, and municipal regulations concerning confined space
entry. ADS is not responsible for any injuries, damages,
claims, or liability resulting directly or indirectly from the
use of this installation guide or the installation of any ADS
equipment.
3-4
ADS FlowAlert Manual
Investigating Site Characteristics
Before beginning installation activities, conduct a thorough
investigation of site conditions. The physical characteristics of the
pipe affect the flow and determine the procedure for installing the
pressure depth sensor. The manhole environment can affect the
installation and effective operation of the float switch(es). Consider
the following factors and perform the following activities when
installing the sensor, float switch(es), and monitor:

Sensor Installation Method The mounting location
determines the installation method employed for installing the
pressure depth sensor. For pipe installations, pipe size and
shape also influence the method used.
 Standard Installation Select this option to install the
sensor in a round pipe from 8 to 48 inches in diameter.
Standard installations involve attaching the sensor to an
adjustable stainless steel ring that mounts inside the pipe.
 Special Installation Select this option to install the
sensor in a non-round pipe or a round pipe larger than 48
inches in diameter. Special installations involve attaching
the sensor to a steel band secured to the inside of the pipe.
 Wall Installation Select this option to install the sensor
in a manhole or pump station wet well. Wall installations
involve attaching the sensor to a steel strap secured to the
wall.

Pipe Height and Width Measure and record the horizontal
and vertical pipe dimensions.
Note: Specific measurements for pipe height, width, and
shape are required only if the project requires using the
depth data to calculate flow quantity. All relevant pipe
dimensions and measurements must be available for entry
in the Profile® software during monitor configuration and
activation.
Pressure Depth Sensor and Float Switch Installation 3-5

Pipe Shape Taking the appropriate measurements that
precisely reflect the exact pipe shape is essential to obtaining
accurate flow calculations. Therefore, irregular-shaped pipes
will require additional measurements if accurate flow
measurements are essential. Refer to the Profile User’s Guide
(#950015**) for more information.

Manhole Depth Measure the distance from the top of the
manhole to the bottom of the manhole invert. This
measurement may be required to determine the elevation for the
float switch. Distances beyond 35 will require extension cables
for the sensor. Manhole depth and expected surcharge levels
also determine the PSI of the pressure depth sensor to install.

Manhole Obstructions Carefully inspect the manhole for
possible obstructions that may pose a hazard to the hanging
float switch or prevent the float from freely changing position
when the flow is rising or receding. Obstacles or obstructions,
such as ledges, can create an opportunity for the float to
become lodged, producing an inaccurate representation of the
float switch state.

Assembling the Ring
The pressure depth sensor mounts to a stainless steel ring that is
installed in the pipe. Several different ring sizes exist, and each ring
is adjustable within about 3 inches to fit pipes of different
diameters. Assemble the ring as follows:
Note: These instructions generally apply to overlapping
rings. However, the 8-, 10-, and 12-inch rings do not have
an overlapping section. Therefore, these non-overlapping
rings will require small modifications to the assembly
process. To assemble a non-overlapping ring, proceed
directly to step 4.

ADS FlowAlert Manual
Although the spreader mechanism fits snugly against the inside of
the ring, the spreader mechanism may seem loose on the hex nuts.
Do not be concerned. The spreader mechanism will tighten once
the ring is installed and tightened inside the pipe. The following
picture displays how a properly assembled ring should look.
Mounting the Pressure Depth Sensor to the Ring
The following section provides instructions on mounting the
pressure depth sensor to the ring. To ensure the most accurate flow
data, standard pipe installations require proper positioning of the
sensor on the ring as well as in the pipe. When facing the
downstream edge of the ring, the sensor should be mounted on the
bottom of the ring.
Proper positioning of sensor on the ring
Caution: Handle the sensor and cable with extreme care.
They contain delicate mechanisms and electronics. Keep
sharp objects away from sensor cable, and avoid stepping
or placing heavy objects on the cable during installation.
Mount the pressure depth sensor to the ring in the following way:
1.
Orient the ring so that the ring’s spreader mechanism is directly
on top.
Pressure Depth Sensor and Float Switch Installation 3-17
2.
Use two 4-40 x 5/16-inch stainless steel screws (do not
substitute any other screws) to mount the pressure depth sensor
on the bottom inside of the ring with the pointed end of the
sensor facing upstream. Mount the pressure depth sensor
slightly to the left of bottom center when excessive silt is
present.
Mounting the pressure depth sensor to the ring
3.
Secure the sensor cable to the ring. Refer to the next section,
Securing the Cable to the Ring, for instructions on properly
securing the cable.
Securing the Cable to the Ring
Securing the pressure depth sensor cable to the ring helps prevent
debris from collecting between the cable and the ring or catching on
the loose cable. It also prevents the loose cable from disrupting the
flow.
Secure the sensor cable in the following way:
1.
Starting at the sensor location, begin securing the cable with 4inch x 0.08-inch cable ties through the pre-drilled holes along
the downstream trailing edge of the ring up the side of the ring.
Run the cable up the side of the ring opposite the spreader
mechanism (the left side of the ring when facing the
downstream edge of the ring).
3-18
ADS FlowAlert Manual
Sensor cabling
2.
Continue securing the cables until reaching the top of the pipe.
3.
Pull the ties until they are taut.
Warning: Do not over-tighten the cable ties or kink the
sensor cable! The pressure depth sensor cable sheathes
two components: the electrical cables that operate the
sensor and an air tube that ventilates the sensor. Overtightening the ties or kinking the cable can damage or
restrict the air tube, causing incorrect pressure depth
readings. In addition, make sure the connector-end of the
sensor is not kinked, does not contain moisture, and
includes an attached dryer tube filled with active blue
desiccant.
4.
Use the diagonal cutters to cut off the excess portion of the
cable ties.
Installing the Ring in the Pipe
The ring must fit securely in the pipe with the sensors properly
positioned to ensure the most accurate monitoring results. Install the
ring in the pipe in the following way:
1.
Examine the pipe for possible obstructions to the flow or
inhibitors to ring installation.
2.
Adjust the ring size to slightly less than the pipe diameter
before placing the ring in the pipe by turning the spreader
mechanism adjustment nut clockwise.
Pressure Depth Sensor and Float Switch Installation 3-19
3.
Place the ring in the input pipe at least 12 inches upstream from
the manhole or edge of the pipe with the sensors facing
upstream toward the oncoming flow. It should be located far
enough upstream from the manhole to minimize the effect of
the draw-down caused by a possible drop in the manhole invert.
Installing the ring at least 12 inches upstream from the manhole invert
Keep the following in mind:
 Make sure the spreader mechanism is at the top (crown) of
the pipe and the pressure depth sensor is at or near the
bottom of the pipe, above any silt present and below the
flow surface (during minimum flows).
Proper orientation of the ring with the sensors in the pipe with and without
silt present
3-20
ADS FlowAlert Manual
 If necessary, temporarily clear away silt to install the ring.
Restore the silt after fully securing the ring (step 7).
 Make sure the ring is flat (flush) against the inside wall of
the pipe to avoid obstructing the flow or catching debris.
4.
Expand the ring by turning the spreader mechanism nut
counter-clockwise with the crank handle or socket. Continue
tightening the ring until it fits securely and completely flush
against the pipe wall.
Warning: Avoid over-tightening the ring. This could
bend the crank assembly.
5.
Restore any silt moved to its previous level, and confirm that
the pressure depth sensor is still above the silt level.
6.
When the sensor is not located at the bottom of the pipe,
determine the physical offset for the pressure depth sensor by
measuring the vertical distance from the bottom of the sensor to
the bottom, center of the pipe.
Note: This value will be necessary when configuring the
monitor using the Profile software.
7.
Secure the sensor cable from the ring to the future monitor
location in the manhole. Refer to page 3-36 for more
information.
Special Installations
A special installation involves installing the mounting hardware for
the pressure depth sensor directly to the pipe surface with anchor
bolts, without the use of spreader mechanisms or rings.
Pressure Depth Sensor and Float Switch Installation 3-21
Performing a special installation involves the following process:

Gathering the parts and supplies

Gathering the tools and equipment

Mounting the pressure depth sensor

Securing the cables to the band
Before beginning the installation, conduct a thorough investigation
of hydraulic and other site conditions. The hydraulics of a site
directly affect the monitor's ability to accurately measure flow
depth. In addition, measure the horizontal and vertical pipe
dimensions carefully.
Caution: Handle the pressure depth sensor and cable
with extreme care. The sensor and cable contain delicate
mechanisms and electronics. Keep sharp objects away
from sensor cable, and avoid stepping or placing heavy
objects on the cable during installation.

Mounting the Pressure Depth Sensor
Two special installation methods are available for mounting the
pressure depth sensor:

¾-band mount

½-band mount
Both mounts require almost identical installation methods. The
only significant differences are that the ¾-band mount allows the
installer to secure the band to both sides of the pipe wall and to
position the pressure depth sensor at the bottom center of the pipe.
These options are not possible using the ½-band mount. Therefore,
the ¾-band mount is the preferable method for mounting the sensor.
However, a ½-band mount may be appropriate for monitoring under
the following circumstances:

Large pipes with deep minimum flows

Large pipes with excessive silt present
3-24
ADS FlowAlert Manual
½- (left) and ¾-band (right) mounts
¾-Band Mount
Perform the following procedure to mount the pressure depth sensor
in a pipe using the ¾-band mount:
1.
Use a hacksaw to cut the band to the appropriate length. Cut
the band so that, when installed, it will run approximately ¾ of
the length around the inside of the pipe.
Note: The metal bands come in 8-foot lengths. Some
larger pipes may require attaching two bands together. In
addition, for square-shaped pipes, use an 8-foot straight
metal strip.
2.
Determine which end of the band will be the long end (end
extending almost completely up one side of the pipe). For
cable routing purposes, ADS recommends reserving the left
side of the pipe (upstream from the manhole) for the long end
of the band.
Note: Position the edge of the band with the cable tie
holes (edge with small holes) facing downstream.
3.
Determine the appropriate location on the band to mount the
pressure depth sensor, making sure the sensor will be both
Pressure Depth Sensor and Float Switch Installation 3-25
above the silt level and below the flow surface during minimum
flows.
 If silt is not present, locate the sensor on the band so it will
be at the bottom center of the pipe once installed.
 If silt is present, locate the sensor slightly up the long end
of the band so it will be above the silt level once installed.
4.
Mount the sensor onto the inside of the band with two 4-40 x
5/16-inch countersink screws, making sure the pointed end of
the sensor faces the upstream edge of the ring (edge opposite
cable tie holes). If holes do not exist on the band at or near the
desired mounting location for the sensor or the sensor does not
have screw inserts, use two medium-sized cable ties to secure
the sensor to the ring. Crisscross the cable ties across the top of
the sensor and underneath the band.
5.
Secure the sensor cable along the downstream edge of the long
end of the band according to the instructions on page 3-29.
6.
Position the band in the pipe so that the sensor will remain
below the flow surface (even during minimum flows) and
above the silt level.
7.
Make sure two pre-drilled holes are visible above the flow
surface on the short end of the band. Maneuver the band so
that the lowest hole is almost at the flow surface.
8.
Mark the pipe wall through the lowest hole with a drill, and
install a ¼-inch x 2 ¼-inch anchor bolt with a pneumatic drill.
9.
Secure the band to the anchor bolt with a washer and nut.
10. Conform the band to the pipe wall around to the long end of the
band so that it is flush with the pipe wall.
Note: Temporarily remove any silt preventing the band
from sitting flush against the bottom of the pipe.
11. Install a ¼-inch x 2 ¼-inch anchor bolt through the pre-drilled
hole closest to the flow surface on the long end of the band, and
secure the band with a washer and nut.
3-26
ADS FlowAlert Manual
12. Make sure the band and sensor are flush against the pipe wall
with no gaps, and conform the rest of the band to the pipe wall.
13. Install ¼-inch x 2 ¼-inch anchor bolts, nuts, and washers at the
pre-drilled hole at the short end of the band and at the predrilled holes along the long end of the band (above the flow
surface) approximately every 12 to 24 inches to the top end of
the band.
Note: Whenever possible, secure the band with an
additional anchor bolt approximately 3 inches below the
flow surface on each side of the pipe. This will help
ensure that the band remains flush against the bottom of
the pipe below the flow surface.
Sensors mounted using a ¾-band mount in the pipe with and without silt
14. Measure the physical offset for the pressure depth sensor (i.e.,
the vertical distance from the bottom of the pressure depth
sensor to the bottom, center of the pipe).
Note: This value will be necessary when configuring the
monitor using the Profile software.
15. Run the sensor cable from the sensor location in the pipe to the
monitor location in the manhole according to the instructions
on page 3-36.
Pressure Depth Sensor and Float Switch Installation 3-27
½-Band Mount
Perform the following procedure to mount the pressure depth sensor
in a pipe using the ½-band mount:
1.
Use a hacksaw to cut the band to the appropriate length. Cut
the band so that, when installed, it will run almost completely
down the left side of the pipe.
2.
Determine the best location on the band to mount the pressure
depth sensor. The sensor should mount as close as possible to
the bottom of the band, making sure the sensor will be both
above the silt level and below the flow surface once installed.
3.
Mount the sensor onto the inside of the band with two 4-40 x
5/16-inch countersink screws, making sure the pointed end of
the sensor faces the upstream edge of the ring. If holes do not
exist on the band at or near the desired mounting location for
the sensor or the sensor does not have screw inserts, use two
medium-sized cable ties to secure the sensor to the ring.
Crisscross the cable ties across the top of the sensor and
underneath the band.
Note: The edge of the band with the cable tie holes is the
downstream edge.
4.
Secure the sensor cable along the downstream edge of the band
according to the instructions on page 3-29.
5.
Place the band in the pipe upstream at least 12 inches from the
manhole invert. Position the band on the left side of the pipe so
that the sensor will remain below the flow surface (during
minimum flows) and above the silt level.
6.
Orient the band so that one of the pre-drilled anchor bolt holes
is just above the flow surface.
7.
Spot drill the pipe wall through the hole, install a ¼-inch x 2 ¼inch anchor bolt, and secure the band to the anchor bolt with a
washer and nut.
3-28
ADS FlowAlert Manual
Note: Make sure the submerged portion of the band is
flush with the pipe wall. If it is not, remove the band and
conform the band to the pipe.
8.
Install a ¼-inch x 2 ¼-inch anchor bolt, washer, and nut below
the flow surface 1 to 3 inches away from the pressure depth
sensor on each side. This will hold the sensor securely against
the pipe wall and prevent the end of the band from twisting in
the flow or catching debris.
9.
Conform the portion of the band above the flow surface to the
pipe wall, and install an ¼-inch x 2 ¼-inch anchor bolt, nut,
and washer every 12 to 24 inches up to the top of the band.
Completed ½-band mount in pipe
10. Measure the physical offset for the pressure depth sensor (i.e.,
the vertical distance from the bottom of the sensor to the
bottom, center of the pipe).
Note: This value will be necessary when configuring the
monitor using the Profile software.
11. Run the sensor cable from the sensor location in the pipe to the
monitor location in the manhole according to the instructions
on page 3-36.
Pressure Depth Sensor and Float Switch Installation 3-29
Note: If the pipe is large and the pressure depth sensor
cable cannot reach the pipe crown, attach the sensor cable
to ½-inch PVC tubing and anchor the tubing to the wall.
This will help prevent sensor damage during heavy flow.
Securing the Cable to the Band
Securing the pressure depth sensor cable to the band helps prevent
debris from collecting between the cable and the band or catching
on the loose cable. It also prevents the loose cable from disrupting
the flow.
Secure sensor cable as follows:
1.
Starting at the appropriate sensor location, begin securing the
sensor cable with 4-inch x 0.08-inch cable ties through the predrilled holes along the downstream trailing edge of the band up
the side of the band. Run the cable up the left side of the band
(when facing the downstream edge of the band).

Securing the sensor cable from the ring (or band, when applicable),
along the pipe crown, and up the manhole helps prevent debris from
collecting on a sagging cable or between the cable and the pipe
crown.
Do not allow the sensor cable to hang down in the pipe or sag in the
manhole. Loose cables could present a safety hazard in the
manhole or increase the potential for sensor or monitor damage.
The cable should be secured along the pipe crown and manhole wall
under all circumstances.
Note: Do not secure a wireless communication antenna
cable with the sensor cable! Refer to Setting Up Wireless
Communication in Chapter 4, Communication, for
information on securing the antenna cable in the manhole.
Secure the cable from the ring (or band) to the monitor location in
the manhole in the following way:
1.
Wrap the cable with an 8-inch by 0.14-inch cable tie attached
to a plastic anchor installed at the top of the pipe.
Note: If a plastic anchor will not serve as an adequate
anchor for securing the cable based on the structure of the
pipe, install a ¼-inch x 2 ¼-inch bolt instead.
 Drill a 3/8-inch hole in the pipe crown.
 Drive the plastic anchor into the pipe with a hammer until
flush and secure.
 Run the cable tie through the loop in the plastic anchor and
around the cable.
 Tighten the cable tie around the cable, and cut off the
excess cable tie material.
Pressure Depth Sensor and Float Switch Installation 3-37
Warning: Over-tightening the cable ties may damage the
sensor cable.
2.
Secure the cable with a cable tie and plastic anchor every 18 to
24 inches along the pipe crown (when necessary) from the ring
to the manhole. If plastic anchors will not serve as adequate
anchors based on the structure of the pipe, install ¼-inch x 2
¼-inch bolts instead.
3.
Secure the cable every 18 to 24 inches up the side of the
manhole to the monitor location. A loose cable could present a
manhole safety hazard or increase the potential for sensor or
monitor damage. If plastic anchors will not serve as adequate
anchors based on the structure of the manhole wall, install ¼inch x 2 ¼-inch bolts instead.

ADS FlowAlert Manual
Installing the Float Switch in the
Manhole
Installing the float switch(es) at the proper position and elevation in
the manhole is essential to ensuring the status readings received are
accurate and the float can pivot freely with changing flow
conditions. The elevation at which to hang the float largely depends
upon the project requirements and threshold of notification.
However, the optimal position at which to hang the float is the
center of the manhole above the top of the pipe, to avoid the flow
line. Positioning the float in the center minimizes the possibility of
the float encountering potential hazards or obstructions present in
the manhole, particularly while swaying or pivoting.
Because the float switch is suspended in the air or flow, it must be
secured by its cable. Typically, the optimal location at which to
secure the cable is at the top of the manhole just below the rim.
This is the best way to position the float as close as possible to the
center of the manhole and to make it accessible for service or
replacement.
Warning: When installing floats in or adjacent to pump
stations or other facilities with rotating machinery (such as
mixers), ensure the customer signs off on the installation.
If a float and cables were to come loose, they would cause
severe damage to any downstream rotating machinery.

Mounting the Float Switch
Install the float switch in the following way:
Note: Floats are labeled HIGH and HIGH HIGH.
Therefore, always mount the HIGH float at the lowest
monitoring elevation.
1.
Install a ¼-inch x 2 ¼-inch anchor bolt in the manhole wall just
below the rim. Select a location away from the monitor
mounting location and on the opposite side of the manhole
from the rungs. This will reduce the possibility of the float
switch and its cabling striking or getting tangled in the rungs or
monitor.
2.
Establish the proper elevation (representing the trip point) at
which to hang the float switch, and then determine the distance
from that elevation to the anchor bolt.
3.
Measure that same distance from the top of the float switch (top
of the float’s collar where the enclosure meets the cable) up the
cable.
4.
Secure the cable to the anchor bolt using an anchor cable tie at
that location on the cable.
5.
Slowly lower the float switch into the manhole until it is fully
suspended from the mounting location.

Setting Up Wireless Communication
Setting up wireless communication involves installing the antenna at
the monitor location, connecting the antenna to the monitor, and
installing the SIM card in the monitor.
Note: ADS wireless communication products use static
IP address network services provided by AT&T.
Therefore, any installation location designated for wireless
communication must have access to AT&T 850 or 1900
MHz service. Each wireless device will be fitted with a
SIM (Subscriber Identity Module) card that is provisioned
by AT&T with specific account and network information
for use with ADS software.
Note: Customer-supplied SIM cards cannot be used with
the ADS FlowAlert™.
Installing the Antenna
ADS provides three options for installing the wireless antenna:

In Road This option involves installing the antenna directly in
the road, in dirt, or under other paving materials.

Pedestal This option involves securing the antenna inside a
telecom pedestal installed off the road. ADS recommends
choosing this option when signal strength is poor using road
antennas.

Magnetic Whip This option involves securing the antenna to
a roof or other protected structure where only a minimal
opportunity exists for theft or vandalism.
Note: While this manual describes the installation process
for each antenna option, detailed installation instructions
also accompany all wireless antennas received from ADS.
Communication

 Dry sand
 Commercial asphalt cold patch compound (1 cup)
 Scotch-kote electrical sealing compound (ADS p/n
505171)
 Scotch 130C rubber stretch tape (ADS p/n I45-0001)
2.
Determine the appropriate location in the road near the
manhole to install the antenna, considering the following:
 Locate the antenna in the road no closer than 18 inches and
no further than 30 inches from the manhole in which the
monitor is installed.
 Choose a location that is as flat as possible with stable base
material.
 If possible, select a location where the antenna would
experience minimal direct impact from road traffic.
 Make sure the location exists beyond the manhole’s iron
rim beneath the road surface. This will enable you to
access the manhole corbel when drilling the channel for the
antenna cable.
3.
Mark the location for the antenna installation, and then mark
the location to drill the corbel hole 2.5 to 3 inches back from
the edge of the antenna hole.
4.
Drill a hole from the marked corbel hole location in the road,
through the corbel, and into the manhole using the ½-inch by
36-inch hammer drill bit. This will serve as the channel for the
antenna cable running from the antenna to the monitor in the
manhole. Be careful to avoid any cables in the manhole, and
restart hole slightly to the right or left if mesh is encountered or
resistance occurs.
5.
Cut a 6-inch long by 1.25-inch wide by 0.75-inch deep hole in
the road using the non-rotating demolition hammer (in the
hammer only mode) with the chisel/grinder. This will serve as
the installation location for the antenna. The corbel hole should
travel under the center of this hole.

8.
If the protective cap is not present on the connector at the end
of the antenna cable, clean the connector and tape it up with
rubber stretch tape to protect it from damage and debris while it
is traveling through the channel.
9.
Feed the antenna cable into the hole, through the channel, and
into the manhole. Smooth any rough edges where the cable
enters the corbel hole with the chisel or rubber stretch tape. In
addition, pack rubber stretch tape into cable hole to prevent
asphalt or sealer from entering the cable hole.
10. Remove the white release tape from the antenna element. Be
careful to avoid contacting the black rubber mastic material
with anything until the antenna is ready to be seated.
4-6
ADS FlowAlert Manual
11. Apply a piece of white release tape onto the top of the antenna,
and then seat the antenna into the bottom of the hole. Once the
antenna is firmly seated, remove the release tape.
12. Apply the asphalt on top of the antenna element. When using
asphalt, scoop the warm material into the hole and then pound
it in using a hammer. Place a piece of wood or metal between
the asphalt and the hammer to prevent the hammer from
sticking to the asphalt. Make sure the asphalt protrudes slightly
above the level of the road surface.
13. Sprinkle sand over the asphalt, and pound the sand lightly into
the surface. The sand must be used to ensure the asphalt
remains in the hole.

Profile software, downloading this data to the monitor, and
initiating flow data measurement and logging. The activation data
includes the current monitor firmware (embedded software) and
relevant portions of the LIF and other configuration parameters
necessary to ensure monitoring activities reflect the specific site
conditions and project requirements. The monitor requires these
files and information to properly measure and record the flow.
Activating the monitor also tests communication between the user's
computer and the monitor. To test communication, connect to the
monitor on-site (using the Direct Connection cable) or have an
analyst call the monitor from any telephone or computer at a remote
location while a technician is on-site to verify that the monitor
modem responds. This also will verify the monitor telephone
number entered in Profile.
Monitor activation occurs through the Diagnostics tool in Profile.

Monitor Installation
After installing the sensors and establishing communications, install
the ADS® FlowAlert monitor in the manhole. The monitor may
mount inside the manhole by an aluminum mounting bracket
attached to the monitor and bolted to the manhole wall or rim. The
monitor also can mount directly to a manhole ladder rung by a rung
mount hanging bracket attached to the monitor. The following
procedures for monitor installation apply to most sites. However,
because manholes differ in many ways, some sites may require the
installer to implement slight modifications to the standard
installation technique.
Before installing the monitor at the site, activate the monitor to
verify that the monitor is configured correctly for the application
and that the battery pack (or external power) is operating at an
adequate voltage. Make any necessary changes to the configuration
before mounting the unit. Refer to Chapter 7, Maintenance and
Troubleshooting, for information on replacing the battery pack, if
necessary.
Warning: Using a battery-powered, wireless monitor
without connecting an antenna will significantly decrease
the life of the battery pack.

CHAPTER 7
Maintenance and
Troubleshooting
While the ADS FlowAlert monitor, pressure depth sensor, and
float switches are designed for dependability and durability, all
electronic devices are vulnerable to wear, malfunction, or failure,
particularly in a harsh sewer environment. However, many system
problems can be avoided altogether by performing routine
maintenance and inspections. The design of the monitor enables the
user to perform general diagnostics and troubleshooting to prevent,
isolate, and correct many problems easily. These serve to minimize
unnecessary monitor downtime and data loss.
This chapter provides routine maintenance instructions as well as
general diagnostic and troubleshooting guidelines for isolating and
correcting monitoring system problems.
Warning: Remove the monitor from the manhole before
replacing the battery packs or performing service activities
which may involve disconnecting cables from the monitor.
In addition, disconnect telephone service at the network
interface box before disconnecting cables from the monitor
lid. These activities help prevent possible shock or injury
to personnel as well as damage to the equipment during
service visits at the monitor location.

ADS FlowAlert Manual
Maintaining the System Components
The FlowAlert monitor, pressure depth sensor, and float switches
should receive routine on-site inspections and remote confidence
checks to maintain the equipment in optimal working condition,
minimize monitor downtime, and prevent possible data loss.
ADS recommends performing these inspections following initial
system installation, during site visits, and on a scheduled interval
(i.e., quarterly or during battery pack replacement).
Note: The only service or maintenance activity ADS
permits within the monitor chassis is battery pack
replacement. Therefore, please do not handle, alter,
modify, remove, or replace any other components inside
the monitor. This may void the monitor warranty

Inspect the float switch housing for heavy grease or other
debris. Remove or wipe off any debris using a paper towel.
ADS recommends inspecting the float switch following an
event in which the float contacts the flow to ensure no debris
remains on the float.

Inspect cable ties and other plastic fasteners for signs of
degradation, such as cracks, and replace as necessary.
Inspecting and Replacing the Pressure Depth
Sensor Dryer Tube
Inspect and replace the pressure depth sensor's dryer tube on a
regular basis. Verify the desiccant in the pressure depth sensor’s
dryer tube is still blue. Pink desiccant indicates that it will no
longer absorb moisture. If it appears pink upon inspection, replace
the dryer tube immediately in the following way:
1.
Clip the cable ties securing the dryer tube to the monitor.
2.
Cut the clear flexible tubing running from the dryer tube to the
pressure depth sensor connector at the location close to the
brass barbed fitting on the dryer tube.
3.
Place the dryer tube with the used desiccant aside, but do not
discard.
7-10
ADS FlowAlert Manual
4.
Attach a new dryer tube to the pressure depth sensor by
inserting the brass barbed fitting into the open end of the plastic
tubing running from the sensor connector. Make sure the
tubing seats firmly against the fitting to prevent air or moisture
transfer.
Inserting the brass barbed fitting into the tube
5.
Secure the new dryer tube to the monitor.
6.
Remove the black end cap before reinstalling the monitor in the
manhole.
Note: Replacing the dryer tube quarterly may be
sufficient; however, replace it more frequently when
necessary.
Checking Communication Devices
Inspect the following communication devices during site visits:

Antenna Cable Check the cable for damage, kinks, or breaks
in the cable. Make sure the connector between the antenna
cable and the monitor is dry and sealed with rubber stretch
tape.
Maintenance and Troubleshooting
7-11

Lightning Protection Module Check the lightning
protection module for lightning strikes (visible arcing),
damaged or poor connections, or corrosion. Replace a burned
out module, and repair any bad or corroded connections in the
wiring.

Network Interface Box If any problems exist with the
network interface box, check the connectors to ensure that the
cable entries are tight and waterproof. If this does not resolve
the problem, contact the telephone company.
Note: Make sure both the lightning protection module
and network interface box are still waterproof.

ADS FlowAlert Manual
Troubleshooting
The FlowAlert monitoring system contains several different
components that perform many different functions. Since a
malfunctioning component increases the risk of losing data,
isolating the part containing the problem quickly is essential to
performing troubleshooting activities efficiently. Minimizing
monitor downtime is critical.
Consider the following when trying to isolate the component or
subsystem exhibiting the problem:

Problems affecting only one of the subsystems are usually
caused by one subsystem alone. The problem may exist in the
board, sensor, float switch, or cabling.

Problems affecting more than one subsystem usually can be
traced to a problem with the processor, power source, or
communication lines. Problems in one subsystem can create
problems in other subsystems when the power source or
communication lines are faulty.

Problems with communication lines, clock readings, time
stamps, and data storage intervals usually arise from faulty
processors, incorrect information entered on the user's PC, or
low batteries.

Failures occurring outside a connector (i.e., between a
connector and the field input or output device) may arise from
problems with the field unit or component cabling. Failures
occurring on the inside (i.e., between a connector and the
printed circuit board) may arise from problems with the board
or its cabling.
Note: If possible, collect all monitor data prior to
swapping a sensor/float switch or troubleshooting a
monitor to prevent possible data loss. Swapping a sensor,
float switch, or battery pack does not result in stored data
loss. In addition, remove the monitor from the manhole
Maintenance and Troubleshooting
7-13
before disconnecting cables from the monitor to avoid
possible hazards.
Some problems that occur will not require a site visit, such as
incorrect equipment identification numbers or other system
parameters the user can re-enter on the local PC. However, some
problems will require a site visit. When this is necessary, inform
the analyst any time a field crew is enroute to a monitor location to
troubleshoot problems so that the analyst can attempt to collect the
monitor data before they arrive. If the problem is a faulty monitor
and the analyst cannot collect the data remotely, replace the monitor
and deliver the faulty monitor to the office so the analyst can
attempt to collect the data directly. If the analyst is still unable to
collect the data from the monitor, send it to ADS for repair.
This chapter provides general guidelines for troubleshooting and
correcting problems with the FlowAlert monitor, the pressure depth
sensor, or the float switch(s).
