CHAPTER 4
System Overview and Operation
The FlowShark Pulse is a long-term monitoring system designed for flow
measurement, flow control (Model 20 transmitters only), data storage, and (optional)
remote access via TCP/IP communication. This device primarily is designed for use
in slightly- to heavily-polluted flow of various compositions. It can function in
partially-filled and full pipes of various shapes and dimensions.
The method for measuring flow velocity is based on the ultrasonic
reflection principle. Therefore, to ensure the system operates properly, it
is essential that particles, such as dirt, gas bubbles, or similar objects,
are present in the flow for reflecting the ultrasonic signal sent by the
sensor.
4-2
ADS FlowShark Pulse O&M Manual
Combination Sensor
The FlowShark Pulse uses a combination (combi) sensor that can simultaneously
determine both flow velocity and flow depth. A combi sensor may contain up to two
2 depth measurement devices: a water-ultrasonic device and/or a hydrostatic
(pressure) device.

Water-Ultrasonic Depth Measurement
Water-ultrasonic depth measurement involves using a horizontal sensor crystal to
determine flow depth based on the time difference between transmitting and receiving
a pulse reflected off the flow surface (the transit-time method).
hl =
c • tl
2
Where,
h = Depth Level
c = Transit Time of Sound
t1 = Time Elapsed Between the Transmitted and Received Signals
Sound travels in water at a speed of 4856 feet per second (1480 m/s) at 68 °F (20 °C),
varying at a rate of 0.13 % for each difference in degree Fahrenheit (0.23% for each
degree Centigrade). To ensure accurate depth measurements, all calculations must
compensate for the flow temperature and the travel time of sound in the flow.
System Overview and Operation
4-3
Adding the sensor offset to the measured depth value (h1) determines the depth total
(h). The sensor offset represents the distance from the bottom of the pipe to the
sensor crystal position. The measured depth value represents the distance from the
crystal to the flow surface.
Pressure Depth Measurement
The combi sensor may have an integrated hydrostatic depth measurement device.
This piezoresistive pressure sensor operates according to the relative pressure
principle, where the pressure of the standing water column above the sensor is
directly proportional to the depth level. This device can measure depth levels even
when the combi sensor is installed away from the bottom center of the pipe.
During installation, this sensor must be calibrated based on a manual depth
measurement and the position of the sensor in the pipe.
Flow Velocity Measurement
The combi sensor has a piezo crystal for measuring flow velocity. This crystal sends
an ultrasonic pulse at a defined angle into the oncoming flow. All air and/or dirt
particles in the path of the pulse reflect a small amount of the ultrasonic signal. The
size and shape of a particle determines the result of the reflected signal. Together, the
returned signals produce a reflection pattern (Figure 4-2) received by the piezo
crystal. This pattern is converted into electric signals that are loaded into a digital
signal processor (DSP) housed in the sensor.
Fig. 4-2: Conditions at first signal detection
After a certain period, the sensor sends a second ultrasonic pulse into the flow. The
DSP also saves the new reflected signal.
Flow velocities differ at varying depth levels, creating a velocity profile. Therefore,
the distances (or movement) between reflective particles’ initial and subsequent
positions also vary at different depth levels, resulting in a distorted reflection pattern
(Figure 4-3). Several other factors also influence particle reflection and velocity
profile measurement. Rotating particles may exhibit multiple shapes for reflection;
4-4
ADS FlowShark Pulse O&M Manual
particles may exit the measurement range before a subsequent measurement can
occur; and new particles may enter into the measurement range.
Fig. 4-3 Conditions at second signal detection
The DSP checks both of the received reflection patterns for similarities using the
cross-correlation method. All existing signal differences are rejected so that the two
similar, but temporarily offset, signal patterns remain for velocity evaluation.
Based on the depth levels, both patterns are subdivided into 16 measurement
windows. The DSP then examines the lag ∆t (change in time – Refer to t1, t2, and t3
in Figure 4-4) of the signal pattern for each measurement window.
Fig. 4-4 Echo signal images and evaluation
The angle of the beam, the interval between the transmitted signals, and the lag ∆t of
the signal pattern for each measurement window determine the flow velocity. The
profile of the acoustic path indicated on the display reflects the mathematical
integration of the individual velocity measurements.

A 3-dimensional representation of the flow velocity distribution can be rendered from
a velocity profile performed at a location with a known pipe height and geometry

Air-Ultrasonic Depth Sensor
An air-ultrasonic depth sensor uses horizontal sensor crystals to determine the
distance (range) from the sensor to the flow surface based on the time difference
between transmitting and receiving a pulse reflected off the flow surface (the transittime method). The flow depth is calculated by subtracting the range and the sensor
offset from the pipe height. The sensor offset represents the distance from the top of
the pipe to the sensor crystal position.
The air-ultrasonic sensor is not effective for depth measurement when the sensor
becomes submerged or depths occur within 4 inches of the sensor crystal, known as
the deadband.

Pipe Insertion Sensor
The pipe insertion sensor primarily is used to measure flow velocity in closed pipes
that remain full, eliminating the need for a depth measurement device. When
installed, the sensor mounts perpendicular to the pipe and extends from the outside of
the pipe, through the pipe wall, and slightly into the flow.
The pipe insertion sensor uses the same technology for measuring velocity as the
velocity component of the combi sensor. Therefore, refer to the Flow Velocity
Measurement on page 4-3 for more information on the method employed by this
sensor for velocity measurement.

Delivery and Receipt
Delivery of a typical FlowShark Pulse measurement system includes the following:
z
Instruction manual including all the necessary steps to correctly install and
operate the measurement system and the certificate of conformity
z
FlowShark Pulse Model 10 or 20 transmitter
z
Ultrasonic sensor: combi sensor or pipe insertion sensor with threaded cutting
ring (consisting of spigot nut, cutting ring, and pipe double nipple)
Additional accessories, such as a pressure compensation element (when using combi
sensors with an integrated pressure measurement cell), memory cards, card readers,
pipe mounting systems, or separate depth measurement devices (such as an airultrasonic sensor), also may be included in the order.
Upon receipt, please inspect the hardware and verify all standard equipment and
accessories according to the invoice to ensure the order is complete and intact. If
damage has occurred in transit, immediately report the damage to the carrier and send
a written report to ADS.
Please provide a written report of any missing items to an ADS representative within
two weeks.
Resolve all problems immediately!
Delivery, Maintenance, and Handling 5-3
Maintenance
Because the measurement system primarily exists in a wastewater
environment, it may be contaminated with hazardous germs.
Therefore, please take special precautions when handling the
transmitter, cables, sensors, and associated equipment.
The FlowShark Pulse is extremely durable, is virtually maintenance-free, and does
not require calibration. The only item in the system that requires maintenance is the
combi sensor with the integrated pressure measurement cell.
If necessary, clean the transmitter enclosure with a dry, lint-free cloth. For heavy
soiling, ADS recommends using a mild detergent. Do not use abrasive cleansers!
To clean the enclosure surface with a damp cloth, first disconnect
the unit from the main power supply.
In flow that contains a significant amount of debris and/or pipes that experience a
substantial amount of silt, it may be necessary to clean the sensor regularly using a
plastic bristle brush, broom, or similar tool.
Do not use hard objects, such as wire brushes or scrapers, to clean
the sensor. A water hose with a maximum pressure of up to 50 psi (4
bars) can be used to clean most sensors. However, do not use a
water hose to clean a flow velocity sensor with a pressure
measurement cell (Types 3K and 4K).
Do not use a high pressure device for cleaning. This could damage
the equipment, producing measurement failure.
Due to the physical design of sensors with pressure measurement cells, these sensors
experience long-term drift in depth measurements (see Chapter 2, Overview and
Specifications). Therefore, ADS recommends calibrating sensors with integrated
pressure measurement cells twice a year relative to the respective zero point. The
best results are produced when the depth level is as low as possible or the sensor is
independent from the measurement medium. Refer to Chapter 8 for the calibration
procedure.
To ensure reliable, accurate, and trouble-free operation of the flow measurement
system, contact ADS to perform an inspection of the equipment at least once a year.
5-4
ADS FlowShark Pulse O&M Manual
To identify the zero point for the pressure measurement cell, consider
measuring the current depth level with a yardstick, ruler, or similar
tool without removing the sensor from the flow. However, keep in
mind that this method can produce errors. Inserting the ruler (or
yardstick) into the flow creates a surge that could lead to
measurement errors based on the current flow velocity. When this a
concern, another method for determining flow depth involves
measuring the distance from the top of the pipe to the flow surface
(commonly referred to as “range”) and subtracting this distance
from the pipe diameter.
Remove combi sensors with the pressure measurement cell (Type 3K
and 4K) if the pressure depth measurement component fails. Rinse
this sensor with clean water for a sufficient amount of time and then
carefully rinse the pressure duct or clean it with a soft brush.
Do not use high pressure water to flush the duct. This could damage
or destroy the built-in pressure sensor.
In addition, never remove the ground plate. This could increase the
potential for leakage or permanent damage to the sensor.

CHAPTER 6
Installation
Reading and following the installation instructions before initial start-up will help
ensure success in flow measurement and device configuration. Do not initiate startup until installation is complete and verified. If any problems occur during
installation, connection, or configuration, please contact an ADS representative.
Installation should be performed only by qualified personnel according to all
statutory standards, regulations, and technical rulings. During installation, refer to all
local regulations regarding electronic equipment.
Protect the FlowShark Pulse power supply separately using a 6amp slow-blow fuse and isolate it from other facility parts through
a separate turn-off. For example, consider using an automatic
cut-off.
Successfully complete transmitter and sensor installation before providing the rated
voltage.
All outer circuits, wires, and lines connected to the device must have a minimum
isolation resistance of 250 volts. Voltages exceeding 42 volts DC require an isolation
resistance of at least 500 kOhm.
The cross-sectional dimension of the power supply wires must be 0.03 square inches
(0.75 mm2) and in accordance to IEC 227 or IEC 245. The device protection rating is
IP 65.
The maximum allowable switching voltage on the relay contacts must not exceed 250
volts. According to Ex protection, this voltage must be verified if the device’s power
supply will be integrated into the facility’s emergency shutdown procedures.

z
Vibration
z
Radioactive emissions
To fasten the wall mount enclosure, use one of the following fastener configurations
based on the composition of the mounting structure:
z
Four M5 machine screws of suitable length with corresponding nuts and
shims. These screws must penetrate the wall at least 1.575 inches (40 mm).
z
Four wood screws with a minimum diameter of 0.177 inches (4.5 mm).
These screws must penetrate the appropriate dowels at least 1.97 inches (50
mm).
The clear door on the measurement transmitter has a protective film to prevent
potential damage during transport and scratches during assembly. Remove this film
immediately after assembly.
Exposing the film to direct solar radiation for a long period will
make it more difficult to remove the film.
Clean the door with mineral spirits or car polish, when necessary. If these cleansers
are not effective, order a new front door from ADS.
The FlowShark Pulse Model 10/20 transmitter does not support
passive OCS sensors (older models).

Use the glands supplied to connect the following outer cable cross-sections:
z
M16 x 1.5: 3.5 mm – 10.5 mm (0.138 – 0.413 in)
z
M20 x 1.5: 6.0 mm – 14.0 mm (0.236 – 0.591 in)
To use a cable with a diameter outside of the specified tolerance, use a gland that
ensures IP 65 minimum protection.
Protect unused wire access openings with an appropriate dummy plug before initial
start-up.
The transmitter has terminal clamps that accommodate power supplies and
digital/analog outputs/inputs with single and multi-wired cables with cross-sectional
areas of 0.007 – 0.098 inches² (0.18-2.5 mm²).
The combi, air-ultrasonic, and 2-wire level sensors have connection plugs for
handling purposes. The cable ends of the FlowShark Pulse sensors or single and
multi-wired cables with cross-sectional areas of 0.007-0.098 inches² (0.18-2.5 mm²)
can receive these plugs.
The 7-pole plug-and-socket connections of the flow velocity sensors are
interchangeable. However, the hardware configuration does not support switching
between 7-pole and 9-pole plug rails (9 poles = level sensors).
Connecting terminal clamps requires a slotted screwdriver with a 0.118- or 0.138inch (3.0-mm or 3.5-mm) blade. Connect the sensors to the plugs using a slotted
screwdriver with a 0.079- to 0.098-inch (2.0-mm to 2.5-mm) blade.
While the terminal clamps typically arrive unscrewed upon delivery, please verify
they are unscrewed before connecting the power supply or the signal wires.
Before making the first connection, apply slight pressure to the
screw on the clamping connection to ensure safety in opening and a
proper connection.
Water or dirt must not leak into the terminal housing. Therefore,
please seal the housing with the lid and two screws supplied.
Position lid with the beveled side up (it is not reversible). An
improper or faulty seal will not provide adequate protection.

Sensor Installation and Connection
Choosing a Suitable Location for Sensor Installation
Clear and stable hydraulic conditions are essential for obtaining accurate sensor
measurements. Therefore, consider the following when inspecting the physical and
hydraulic conditions at all potential installation locations:
z
Strictly avoid locations experiencing or near draw-downs, steps, curves,
obstructions, pipe joints, profile changes, or immediately upstream or
downstream of inlet or lateral connections.
z
Choose a location where sedimentation (sand, grit, sludge, etc.) does not
develop under normal flow conditions. Sedimentation can accumulate due to
friction in pipes at locations exhibiting minimal or negative slope or structural
deficiencies that create obstructions or pockets. Typically, channels that
regularly exhibit flow velocities of more than 2 feet per second will not
experience a buildup of sediment.
z
Avoid measuring flow depth in closed pipes that remain at least 80 percent
full under normal flow conditions. These sites can fill up completely during
elevated or peak flows, potentially resulting in backup or surcharge
conditions.
z
Avoid locations that exhibit significant changes in slopes.
z
In general, make sure the distance of the upstream approach to the sensor is 5
times the approximate diameter of the pipe and the distance downstream from
the sensor is 2 times the approximate diameter of the pipe. However, consider
longer straight approaches when turbulent hydraulic conditions generate
distorted flow profiles.
The following figures provide examples of appropriate and problematic sensor
installations. Please forward any applicable drawings/photos and contact your ADS
representative for assistance in selecting an appropriate location or in assessing
potential locations to install sensors for accurate flow measurements.

Sensor Installation
When installing the sensors, use only non-corrosive fastening materials and fasten the
sensors both securely and tightly.
To avoid disturbances from electrical interference, do not locate
sensor cables close (or parallel) to an engine (motor) or main
power lines.
Combi Sensor
Fasten the sensor through the four holes on the front and reverse sides of the ground
plate (Figure 6-12, detail Y). Use the slotted holes (Figure 6-12, detail X) to snap the
sensor onto a special base plate (Type BST) for use in conjunction with the pipe
mounting system. Never use the slotted holes to install the sensor with screws or
similar fasteners.

Figure 6-12 Combi sensor dimensions (X represents slotted holes for fastening on the pipe mounting system; Y
represents 4 x countersunk holes M6 for direct fastening)
To install the combi sensor on the pipe bottom, use 4 stainless steel screws of
sufficient length (between 1.18 and 2.76 inches (30 and 70 mm)) with the
accompanying dowels. ADS does not recommend using studs or similar bolts.
Determine the length of the screws based on the consistency and integrity of the
structure to which the sensor will be secured. Choose an adequate length to ensure
the sensor can be safely and securely fastened and the installation will remain durable
under any operational conditions.
Screws and fasteners extending into the flow can introduce
turbulence or build-up in a wastewater environment, potentially
resulting in erroneous flow measurements. Therefore, use wellfitting, counter-sunk screws and screw them completely into the
mounting plate so they are as flush as possible with the plate.
Install the sensor at the bottom the center of the pipe (unless instructed otherwise by
ADS) with the beveled side facing upstream toward the oncoming flow.
When using a combi sensor with simultaneous water-ultrasonic depth detection,
install the sensor parallel with the flow surface and no more than ±2 ° from the
Installation 6-11
bottom center of the pipe. Higher depth levels and/or flow velocities may produce
erroneous measurements if the sensor is not installed properly.
When using a combi sensor with water-ultrasonic and pressure measurement
capability, environmental conditions, such as the Bernoulli effect, may produce
erroneous measurements in the presence of high flow velocities and low depth levels.
Under these conditions, ADS recommends taking ultrasonic measurements using the
air-ultrasonic sensor from the top of the pipe and pressure depth measurements from
the bottom in the flow simultaneously until flow depth levels reach an adequate depth
to implement water-ultrasonic depth measurement using the combi sensor.
Although the design of the sensor significantly limits build-up from debris in the
flow, the sensor mounting plate is more susceptible to build-up. Therefore, make
sure that no gap exists between the sensor mounting plate and pipe bottom. Seal any
gap or seam that may exist around the tip of the sensor following installation with
silicone or a similar material.
The bottom of the pipe must be completely flat (plane surface) for
sensor installation. Otherwise, the sensor could experience
damage or leakage, resulting in potentially irreparable damage to
the electronic components.
Do not bend the ground plate during installation or removal. Use
only an appropriate screwdriver for sensor removal; do not use a
pry bar, chisel, hammer, lever, crowbar, hammer drill, or similar
tool. In addition, do not use excessive force to remove the sensor.
Do not remove any sensor parts! Removing or loosening the
ground plate and/or cable glands on the sensor will result in
leakage and sensor failure.
For sensors without integrated pressure elements, consider installing the sensor in a
depression at the pipe bottom up to 0.47 inches (12 mm) deep. This will minimize
the lowest measurable depth level and the susceptibility of the sensor to the build-up
of debris. Once installation is complete, fill up the remaining gaps and seams with a
permanently elastic material, such as silicone.
Never countersink combi sensors with integrated pressure
measurement cells. The sealing material on the sides of the
countersunk sensor or accumulated debris/silt could result in
erroneous measurements and/or pressure measurement cell failure.

Figure 6-13 Suggestion for installing countersunk combi sensors
Make sure the combi sensor is not covered with or deposited in
filling material. This could result in signal attenuation or
erroneous measurements.
Run the sensor cable along the pipe bottom from the back of the sensor to the pipe
wall. To minimize build-up, cover the cable with a thin, stainless steel sheet or lay it
in a small canal on the pipe bottom and then seal the canal with a permanent, elastic
material. Appropriate covers are available through ADS.

Figure 6-14 Suggested cable layout
Do not run the cable loosely, uncovered, or across the silt at the
bottom of the pipe. This could lead to a build-up of debris and/or
cause the sensor or the cable to pull apart.
Installation 6-13
Figure 6-15 Hints on cable layout (1 represents the protective cover)
Do not bend the standard signal cable in more than a 3.94-inch
(10-cm) radius. Bending it into a smaller radius could break the
cable and, for certain sensors, produce kinks in the cable and
create obstructions in the air compensation hose (resulting in
erroneous depth measurements).
The cables of high-resistance sensors (special models) are coated with an additional
transparent FEP jacket that protects the cables against organic solvents, acids, and
lye. Do not damage (such as cut, penetrate, or crush) or remove this protective jacket
under any circumstances.
Handle high-resistance sensors equipped with additional protective
jacket (cables with FEP jacket) with care. Do not damage or crush
the protective jacket in any way.
The minimum bending radius of cables with protective FEP jackets
is 5.91 inches (15 cm). Bending the cables in a smaller radius may
damage the protective jacket, resulting in sensor malfunction.
Combi Sensor with Integrated Pressure Measurement Cell
To compensate for atmospheric pressure, sensors with integrated pressure
measurement cells have an air hose located inside the cable. Do not buckle or seal
this air hose or clamp the hose into hermetically sealed connection sockets without air
pressure compensation. The pressure cell will not be able to measure flow depth
accurately under these conditions.
Pipe Insertion Sensor
The pipe insertion sensor would be most suitable in applications such as closed pipes
that remain full. To install the sensor, screw it tightly into the 1½-inch nozzle using a
cutting ring and spigot nut. The cutting ring of the sensor will warp during
installation and, therefore, cannot be used again. Therefore, to obtain new cutting
rings, please contact an ADS representative..
Another installation option would involve using a ball valve to
allow for sensor removal without applying pressure or a
retractable fitting to allow sensor removal and replacement under
operational conditions.
6-14 ADS FlowShark Pulse O&M Manual
Make sure the horizontal part of the sensor is flush with the pipe wall once installed
(Figure 6-16, far left).
Figure 6-16 Proper pipe insertion sensor installation (left – represents a proper installation; center – represents a
poor installation due to build-up; right – represents a poor installation due to faulty readings or sensor failure)
Install the sensor so that the beveled side is facing upstream. The “installation help”
screw (Figure 6-17) assists in proper positioning.
Figure 6-17 Pipe insertion sensor dimensions
When using a pipe insertion sensor with simultaneous ultrasonic depth detection from
bottom up, please install the sensor perpendicular to the flow surface and no more
than ±2 ° from the bottom center of the pipe. Improper installation could produce
erroneous depth measurements under high depth and high flow velocity conditions.
When assembling the pipe insertion sensor, use a special grease for
the stainless steel couplings (DIN 2353, or equivalent). Apply a
small amount of grease to the cap nut thread, threads, cone, and
cutting ring during pre-assembly. The screw joints come pregreased from the manufacturer. Purchase additional grease
through ADS, when necessary.

Air-Ultrasonic Sensors
Install the air-ultrasonic sensor with clamping using an pipe mounting system. To
install the sensor using this mounting system, run the mounting sheet located in the
pipe vertex (crown) through the cut-out (Item 4 on Figure 6-19) in the air-ultrasonic
sensor prior to final assembly.

Before clamping the system into the pipe, adjust the sensor so that it is completely
parallel to the water surface. When installing an air-ultrasonic sensor and combi
sensor measuring flow velocity together, locate the air-ultrasonic sensor upstream at
least 4 inches (10 cm) ahead of the combi sensor at the bottom.

The air-ultrasonic sensor has a 4-inch (10 cm) deadband and,
therefore, cannot measure depths within this range.
If depths occur within this deadband, the FlowShark Pulse will
indicate a fixed distance of 4 inches (10 cm) below the airultrasonic sensor, producing erroneous flow quantity
measurements.
If the air-ultrasonic sensor becomes submerged, the sensor will
send the signal directly into the flow. Since sounds travels faster in
flow than in air, erroneous depth measurements are likely to occur.
Therefore, do not include the deadband in the maximum depth
parameter for the air-ultrasonic sensor. Instead, configure the
equipment to obtain depth readings within this range from the
pressure sensor.
Sensor Connection
A sensor with an integrated pressure cell has a Type LIY11Y 2x1.5 mm² + 1x2x0.34
mm² + PA 1.5/2.5 custom cable.
Sensors without a pressure measurement cell have Type LIY11Y 2x1.5 mm² +
1x2x0.34 mm² cables. These sensors can be extended with single-shielded signal
extension cables without modification.
ADS recommends Type A2Y(L)Y 6x2x0.8 cables (or equivalent cable types) or a
higher number of wires using 2 wires for bus communication. The remaining wires
must be connected in parallel as 2 complete wires for the power supply.
The maximum fixed cable length permitted between the flow velocity sensor and the
transmitter is 450 feet (150 m). A cable length of up to 750 feet (250 m) may be used
if a flow velocity sensor with a 90-foot (30-m) fixed cable is used in conjunction with
a connection box and a signal extension cable with a larger cross-sectional area.
6-18 ADS FlowShark Pulse O&M Manual
The maximum cable length for an LUS air-ultrasonic sensor is 328
feet (100 m). This sensor cable may not be extended.
The signal cable attached to the sensor is not designed for underground burial for an
extended period of time without protection. When burying signal cables in soil,
concrete, or other comparable materials, first run the cable through conduit for
protection. Consider cable removal and replacement when selecting the inner
diameter, bending radius, and layout of protective pipes and hoses.
When extending the sensor cables, please note that the total
resistance of the power supply lines must not exceed:
•
2.100 Ohm for sensors with 30-foot (10-m) fixed cables
•
1.850 Ohm for sensors with 60-foot (20-m) fixed cables
•
1.600 Ohm for sensors with 90-foot (30-m) fixed cables
(Specification corresponds to feed + return wires!)
Longer cable lengths may be used under certain circumstances involving special
cross-sectional cable areas. Please contact ADS for specific guidance.
Do not use common extensions for different installations or a
common signal cable to extend separate depth and flow velocity
sensors.
For sensors with a pressure measurement cell (Types 3K and 4K, the maximum
uninterrupted cable length is 90 feet (30 m). For cable extensions, install a
connection box with a pressure compensation element (Figure 6-23). This pressure
compensation element, available through ADS, must be installed even if the cable of
a sensor with an integrated pressure measurement cell is connected directly to the
transmitter.
Operating sensors with an integrated pressure measurement cell
for a long period without a pressure compensation element may
lead to irreversible damage to the sensor electronics.

FlowShark Pulse Power Supply
FlowShark Pulse models are equipped to operate using either 85-260V AC
(alternating current) or 24 V DC (direct current) power. Two on/off slide switches
exist above the terminals. The 24V switch (Figure 6-35) powers up or down the
auxillary 24-volt DC output and powers down 24-volt DC input.
Figure 6-35 Slide switch position on the bus board
A 24 V DC transmitter cannot be operated with alternating
current; a 230 V AC transmitter cannot be operated with direct
current.
Before connecting a power source to the unit, move the 230V and 24V switches to
the off position. For AC power, wire the 120 V circuit to L1, N, and PE (Figure 636). For 24V DC power, wire to terminals b2 (+) and b3 (–), as shown in Figure 637. If the unit is AC-powered, 24V DC auxillary power is available, as shown in
Figure 6-36 (24V DC, 100 mA maximum).

Installation 6-27
Overvoltage Protection Precautions
To adequately protect the FlowShark Pulse transmitter, the power supply and mAoutput must have protection. ADS recommends EnerPro 220Tr, EnerPro 24Tr surge
arrestors (for 24 V DC) for the mains supply and the DataPro 2x1 24/24Tr for mAoutputs.
The flow velocity sensor and the LUS air-ultrasonic sensor have internal protection
against overvoltage. Provide protection against higher voltages using the DataPro
2x1 24/24 Tr and DataPro 2x1 12/12 –0.3 Tr(N).
Using overvoltage protection elements reduces the maximum
allowable cable length.
DataPro 2x1 12/12 –0.3 Tr(N) overvoltage protection will consume
up to 300 mV. The line resistance is 0.3 Ohm/wire. This resistance
must be taken into account with the total allowable resistance
(refer to Sensor Connection on page 6-17).

6-30 ADS FlowShark Pulse O&M Manual
Regulator Mode
General
A FlowShark Pulse Model 20 is required for managing flow volume, which is
controlled automatically by the transmitter. The FlowShark Pulse Model 10 has
neither an external setpoint input nor the two digital outputs to drive the regulator
slide valve or digital inputs required for slide valve administration. Therefore, when
operating a Model 10, please use an appropriate external controller and program it
according to the manufacturer’s specifications.
Typically, sluice gate valves, knife gate valves, or iris gate valves are used with an
electrically driven three-step controller. Analog-driven slide valves cannot be used.
ADS recommends selecting gate valves based on the following regulating intervals
(i.e., the time elapsed between a completely open valve and completely closed valve):
</= 300 mm (11.8 in) diameter: minimum 60 seconds
</= 500 mm (19.7 in) diameter: minimum 120 seconds
</= 800 mm (31.5 in) diameter: minimum 240 seconds
</= 1000 mm (39.4 in) diameter: minimum
For proper operation and error monitoring of the slide valve, the Way-End-Switches
must turn OFF and ON and the torque switches must turn ON. These signals must
be connected to the digital inputs of the FlowShark Pulse. Please use gold-plated
contacts to ensure contact reliability. Connect a signal relay between the switches
and the FlowShark Pulse digital input to safely conduct the 10 mA input current.
Analog position feedback to the FlowShark Pulse is not intentional.
The FlowShark Pulse operates as a three-step controller with surge detection, quickclose control, slide valve monitoring, and automatic flush function.
Digital inputs 4 and 5 are designated, by default, to drive the regulating unit. Digital
output 4 represents slide valve closed, and digital output 5 represents slide valve
open.
Modifying the assignment of the digital outputs is not permitted.
The input current for the digital inputs of the FlowShark Pulse is 10
mA. Ensure contact reliability by selecting appropriate contact
materials for the end switch of the controlled slide valve.
Installation 6-31
Setting up the Measurement Location
If possible, install the measurement device in front of the regulating unit. This setup
may not acknowledge or consider the response time of the control system. However,
it does prevent or minimize hydraulic disturbances from external vortices
downstream of the regulating unit.
Figure 6-41 Setting up a controlled system, such as a discharge control
If this installation configuration is not possible, install the measurement
device downstream of the slide valve a distance of at least 12 times the
maximum pipe height (Figure 6-42). In addition, inspect the hydraulic
conditions at the location before installing the equipment. To ensure
suitable measurement conditions, establish an adequate distance or
implement appropriate calming measures (such as deflectors or similar
devices) between the gate valve and the measurement location
downstream.
6-32 ADS FlowShark Pulse O&M Manual
Figure 6-42 Setting up measurement to occur behind the slide valve
Please note that extended run times delay feedback from measurement and control.
Therefore, program the control to respond slowly.
If maintaining a minimum distance is not possible, install flow calming elements,
such as rebounding surfaces or returns. Custom design these installations according
to the specific application and contact ADS for guidance.
Figure 6-43 Pipe measuring section
Installation 6-33
Additional Information Concerning Control Systems
Determine the distance between the flow velocity sensor and the corresponding
control slide valve based on the default flow value, nominal diameter, and
preliminary pressure. This distance should be at least 3 times the internal diameter of
the pipe; however, a distance of up to 5 times the internal diameter is preferable,
when possible.
Flow velocities in the control distance should not fall below 0.98 feet per second
(30cm/s) under typical flow conditions to ensure adequate detection.
When using an air-ultrasonic sensor, calculate the required dome height according to
the maximum preliminary pressure.
Please note when using ADS air-ultrasonic sensors:
Minimum dome height [mm] = 350 mm (13.78 inches) + x • 40 mm (1.57 inches)
x=
maximum impound pressure in [m] upstream of
control slide valve
The slide valve should have exactly the same inside diameter as the incoming and
outgoing pipes. Always avoid hydraulic jumps, ledges, weld seams, rising flange
densities, and other structures when choosing a measurement location.
Install pipe insertion sensors slightly off center when sludge and/or silt are present.
Measuring flow depth with the pipe insertion sensor is not possible
when the sensor is not installed at the bottom center of the pipe.

Selecting the regulator function automatically sets relay 4 to for the SLIDE VALVE
CLOSED function and relay 5 for the SLIDE VALVE OPEN function. This default
assignment cannot be modified.
The digital inputs are programmable for providing position feedback. To ensure
proper, reliable slide valve drive response, employ the PATH OFF, PATH ON and
TORQUE OFF messages for the slide valve drive.
Installation 6-35
The input current per digital input is 10 mA.
When driving the slide valves via the digital inputs, always use all
three messages. Activating only one message may destabilize
regulator operation.
The regulator can operate with an external or internal setpoint. When using external
setpoints, always route them to analog input 4.
When using a 4-20 mA signal as an external setpoint, monitor the signal for cable
breaks and short circuits. If errors occur, the FlowShark Pulse will access the internal
setpoint. Always set the internal setpoint when using external 4-20 mA setpoints and
error monitoring.

CHAPTER 7
Initial Startup and Communication
After installing and connecting the FlowShark Pulse transmitter and sensors (refer to
Chapter 6, Installation) and providing power to the unit, the user can communicate
with the unit. The user interface on the FlowShark Pulse enables the user to easily set
up basic and advanced settings on a graphic dialog to ensure reliable device
operation. This interface includes a keypad on the transmitter and is also accessible
through an Internet browser.
Communication with the transmitter through a browser can occur on-site or from a
remote location. Direct communication requires only an Ethernet connection using a
cross-link cable between the user’s PC/laptop and the FlowShark Pulse. Remote
access occurs over a TCP/IP network (LAN) or through an external GSM/GPRS
gateway.
This chapter includes instructions on establishing communication with the FlowShark
Pulse through an Internet brower, reading the display, and operating the keypad.
Review this chapter carefully to become familiar with the display and keypad before

Parameter Settings
8-3
Basics for Setting Parameters
The transmitter operates automatically using the existing settings until the user enters
and accepts new input parameters. Once the user finishes entering all the new
settings, the system will prompt the user whether to accept the new values.
Following confirmation, the user must enter the following code number.
2718
Type in 2718 if prompted.
Do not give this code number to an unauthorized person. In
addition, do not leave the code next to or write it down on the
equipment. This number prevents access by unauthorized users.
If the user enters the wrong code three times, the system will abort the parameter
mode and initiate operation based on the existing parameters. If the correct code is
entered, the system will accept the modified parameters and reset. The reset will take
approximately 20 to 30 seconds.
In addition to saving modified parameters or rejecting modifications (by clicking No
at the end of the parameter setting procedure), the user also can return to the previous
menu level using the Back function. This enables the user to modify settings that
may have been overlooked without saving the settings modified previously.
Figure 8-1 Screen displayed once parameters are set
If the user verifies each parameter without modifying any of the parameters, the
system will not prompt the user at the end.
Because the language, units, contrast, and display brightness parameters only affect
presentation, and not measurement or output, the user is not required to enter the code
after modifying these settings.
This instruction manual describes all the configuration and
programming options for the FlowShark Pulse. The transmitter
type will determine the inputs and outputs available. While the
inputs/outputs may be programmable, they may not be available for

use or connection. Refer to Chapter 4, System Overview and
Operation.
The FlowShark Pulse Model 10 transmitter represents this kind of
scenario because it has only 2 analog outputs, 2 relay outputs, and
1 analog input. This device does not have a digital input and
cannot be operated as a controller. It can be operated only with 2
analog outputs and 2 relay outputs. Please use the Model 20
transmitter to employ digital input and controller functions.
After mounting and installing the sensor and transmitter (refer to Chapter 7,
Installation), activate the power supply.
The initial start-up dialog displayed is language selection:
Figure 8-2 Language Selection
Select the desired language using the arrow keys, and then press Enter to confirm.
Please press the key only one time.
The transmitter initiates communication with the sensor and coordinates both
processor programs. While this occurs, the software version number displays on the
transmitter. This number is required for reference if problems occur during
configuration.
Perform this procedure after each sensor change.
For safety reasons, please reset the system when replacing a sensor by powering
down the transmitter. The user can perform a full reset to the factory default settings
by selecting the load factory setup from the setup parameter submenu of the PAR
main menu.
Once the previous actions are complete, begin setting the parameters.
The unit loses custom parameters during a full reset, restoring the
factory default parameters.

Select the INFO submenu from the day values menu (Figure 8-6). This screen
displays the flow totals for the past 7 days (Figure 8-7), provided the transmitter has
operated without interruption for the past 7 days. If an interruption occurs, it displays
the flow totals for the uninterrupted days of operation.
Flow totals typically are calculated at midnight (00:00 h). Modify the time at which
this will occur, if necessary, through the RUN > Day Values > Interval (Figure 8-8).
The user also can obtain partial totals since the last reset. Reset the total to 0 by
pressing the ALT key. This reset does not modify the totalizer.

Error Messages
This screen monitors any interruptions in unit function. The unit saves and organizes
errors by the type of error and the date and time at which the error occurred. The
ALT key deletes error messages one at a time, from the latest to the oldest.
Deleting an error message before it has been addressed will
prevent it from being written to memory again. However, the error
will surface in the memory once it occurs again (or if the power
supply is briefly interrupted).
Trend
This display functions like an electronic logger. It records average readings at a
designated interval for depth, average flow velocity, and depth (level) for the past 90
days. The user can select and view individual values from a submenu.
Figure 8-9 Trend value selection
The period over which the values have been averaged displays at the bottom of the
screen. New values are added as vertical lines on the right-hand side of the display at
the end of each configured storage interval (Figure 8-10). As new readings display,
older values move to the left and eventually move into the internal memory.
Use the left/right arrow keys to scroll through the time intervals to view older data
sets. Browse through daily values using the up/down arrow keys. This enables the
user to calculate and evaluate previous measurements, trends, dry weather periods,
and possible measurement problems that may have occurred in recent days.
The internal memory has a 90-day capacity. Therefore, new data will overwrite older
data sets in memory.
Scrolling will scale the readings displayed automatically; therefore, these values may
change to represent the most accurate reading available.
The user can set the time interval for the memory in the PAR > Storage Mode >
Interval menu. The factory default setting is a 2-minute interval.

This parameter represents the depth of the sludge that has accumulated at the bottom
of a pipe. This factor must be subtracted from the total wetted hydraulic area before
the FlowShark Pulse performs flow calculations.
8-18 ADS FlowShark Pulse O&M Manual
Low-Flow Volume Qmin.
This parameter exists to minimize the impact of slow-moving flows or noticeable
increases in volume. It primarily is used to measure overflow volumes in structures
that remain flooded by incoming flow.
Qmin: readings lower than this value will be set to 0. The user can only set positive
values, and each value will be considered an absolute value (i.e., very small positive
or negative flows will be set to zero).
Vmin: low-flow volumes in applications with large profiles and depth levels can be
suppressed using this parameter. Lower velocity fluctuations within longer periods of
time may cause apparently large volume fluctuations which cannot be ignored using
the Qmin value function.
Flow velocities below this value will be set to 0, which will ensure a calculated
volume of 0.
The user only can set positive values, and each value will be considered an absolute
value (i.e., very small positive or negative velocities will be set to zero).
Both low-flow suppression setting options have an OR logic relationship to each
other.

Figure 8-30 Example of an installation involving 2 depth sensors
Depth level measurement combinations 6-12 provide reliable readings under difficult
measurement conditions. These involve measurement locations that require more
than one sensor and experience surcharge conditions during rainfall events.
Please note that, when combined depth detection is in use among separate sensors,
the system employs only one method to measure flow quantity. Select the
appropriate method during configuration activities based on the flow depth. To
ensure reliable depth measurements, assess the general hydraulic conditions and
determine the most effective method for measurement at the location.
Enabling the memory mode and installing a memory card ensures all settings and
measurements are saved, providing access to the data for verification and
recalculation purposes at any time.
Determine the appropriate method for measuring depth during the preliminary stages
of project planning.
When choosing the method of measurement, connect a sensor to the
unit that is appropriately equipped for implementing that method.
While universal sensors have broad functionality, they may not be
adequate for acquiring the measurements required.
Mounting height
This parameter represents the height of the depth sensor above the pipe bottom. The
user cannot view or set the mounting height if sensor type 3 or 4 is selected.
This parameter is set to 0.394 inches (10 mm) by default. Do not modify this value
unless the sensor will be installed at a higher or lower elevation. When installing the
sensor higher (such as on a block), enter the total elevation of the 0.394 in (10 mm)
default value plus the additional height. When installing the sensor lower, enter the

value resulting from subtracting the reduced height from the default value of 0.394 in
(10 mm).
When using the air-ultrasonic sensor, enter the distance between the bottom edge of
the sensor and the pipe bottom.
The standard mounting height for the combi sensor with the pressure cell is 0.197 in
(5 mm), which represents the elevation of the sensor diaphragm above the pipe
bottom. It is not necessary to modify this value unless the sensor will be installed
higher or offset sideways. When installed higher, enter the total elevation of 0.197 in
(5 mm) plus the additional height.
Scale
This parameter is available only when sensor type 3 or 4 is selected.
To configure this parameter as a fixed value, enter the persistent water level. For a
full pipe, this value would be equivalent to the inside diameter of the pipe.
When using external sensors, enter the offset (to be added to the reading) and
measurement range (equivalent to 20mA of the FlowShark Pulse analog input).
Adjust the scale according to the measurement range or the scale of the
corresponding external depth sensor’s analog output.
Connection
This parameter is not available if the external depth sensor (sensor type 3, 8, or 10) is

requires these input classifications for regulator operation.
The Lock v-measurement function is available only for digital input 1.
Figure 8-44 Digital input functions
Locking measurements may be useful for challenging applications, such as locations
that characteristically reflect backwater conditions. The unit either releases or locks
the velocity measurement based on a limit value contact, such as a discrete echo
sounder, float switch, or conductive transducer, using the overflow height as the
switching threshold. Locking refers to setting the flow velocity readings to 0. Since
the unit will calculate volume as V=0, no analog or digital values corresponding to
flow will be available.
However, selecting the option to save individual gates will ensure individual velocity
readings are saved.
Channel number

parameters.

Lock V-measurement Configures DI 1 to lock the measurement
exclusively. The display will read Measurement locked. No output from
AO + DO.
This function is designed particularly for locations that characteristically
experience turbulent backwater conditions. To effectively use this function,
the flow velocity reading must be either locked or released at a specific
threshold value corresponding to the peak overflow. For example, detection
could occur using a separate echo sounder, float switch, or conductive sensor.
A locked measurement means that flow velocity reading will be set to 0.
Therefore, the volume will be calculated based on a velocity reading of 0,
eliminating analog or digital flow output. Enabling the option for saving
single velocity gates will ensure the unit saves individual velocity readings
without using them in calculations.
Digital inputs are passive and, therefore, are supplied by an
external 2- V DC power supply. The signal current is 10 mA. To
ensure reliable conductivity, use relay or end switch contacts made
of a high-quality material.
Logic
Toggle between inverse and non-inverse input by pressing ALT. For example, this
can allow a user to configure the unit to view closed slide valve signals under normal
conditions. Therefore, a constant signal level would be equivalent to a disengaged
end switch, allowing the unit to detect cable breaks easily.

available. When this occurs, set the analog output signal for "floating” conditions.
Configure the measurement span so that the zero (0) reading for flow exists in the
middle of the measurement span, such as the following:
4 mA = -1.00 mgd
20 mA = 1.00 mgd
For this example, the signal output for a zero (0) reading for flow would be 12 mA.
Backwater would decrease the analog signal; positive flow would increase the signal.

P-Factor
The P (proportionality) factor indicates the degree to which the regulating time will
be affected when a deviation ∆ w from setpoint w occurs. The higher the
proportionality factor, the longer the regulating time of the slide valve at the same
control deviation.

Interval/cycle time
Set the processing interval for the controller.
Figure 8-59 Setting the interval
8-42 ADS FlowShark Pulse O&M Manual
Shorter intervals will accelerate the control behavior; however, they will cause the
control circuit to oscillate when longer run times exist between the regulating unit
and measurement.
A longer interval will decrease the tendency for the controller to oscillate; however, it
will increase the inertia of the regulating system.
Guideline:
Interval =
average flow velocity
distance between regulating unit and measurement
• 1.3
Control deviation
This parameter defines the amount of deviation that can occur from the setpoint of the
control system without executing a regulating event. This setting reduces the
tendency for the system to oscillate. Hydraulic conditions cause volume
measurements to fluctuate. If there is no tolerance defined for setpoint deviation, the
system will repeatedly attempt to adjust the actual value according to the setpoint.
This may cause the regulating unit to run continuously, potentially resulting in
mechanical defects or deterioration.
Both values have an AND logic relationship to each other. Under this condition, it
typically is sufficient to define a percentage value.
Consider entering an absolute value for external setpoint control (channel network
management) and large controlling ranges. Otherwise, for low setpoints, the
permissible control deviation percentage may be very low. Inputting an absolute
value as well will help avoid control oscillations under these conditions.
Figure 8-60 Setting permissible control deviations
Minimum duration of control impulse
This parameter is similar to the I-component of PID controllers. It defines the
minimum regulating time for a regulating unit to ensure that very short calculated
control impulses mechanically affect the regulating unit. Therefore, specify a longer
duration for the minimum control impulse than required for the combined motor startup time, gear clearance, and slide valve clearance.

Slide valve run time/shifter time
Use this parameter to monitor spindle breaks, slide valve gate breaks, gear defects,

may indicate that the regulating unit is not moving, even when the unit is generating
control signals.
Figure 8-62 Setting the slide valve run time

Guideline:
Slide run time = time elapsed between open and closed condition of slide valve

factor.)
The slide run time produces an effect similar to the P-factor and
must be set.
Quick-close function
Use the quick-close function when certain conditions, such as large diameters, long
slide valve run times, and long dead times, exist at the measurement location. During
sudden rainfall events, this function will partially close the open slide valve
independent of the calculated regulating time. During normal operations, this
function will be executed without any interruption to runtime.

Selecting YES will reset the system to the basic parameter settings.
The default settings will be restored and all customer modifications
will be eliminated (system general reset).
Service code
Entering a special code provides additional system settings options. These options
may include capabilities, such as modifying the beam angle or medium sound of the
velocity sensor, transmit voltages, or special adjustments regarding the transmitter’s
crystal drive. These settings may be modified only by ADS personnel during start-up
activities because they require comprehensive knowledge of the equipment and
should not require adjustment during standard use.
Damping
This menu enables the user to adjust the display and analog output damping between
20 and 600 seconds. A 0 to 100 percent increase in the calculated volume requires
the designated time to pass on either the display or the output.
Based on the damping setting, the FlowShark Pulse reading will fall to 0 if this period
expires without an accurate depth/height measurement.
Damping, Example 1: Damping 30 seconds, jump from 0 l/s to 100 l/s (=100 %) –
unit requires 30 seconds to run from 0 l/s to 100 l/s.
Damping, Example 2: Damping 30 seconds, jump from 80 l/s to 100 l/s (=20 %) –
unit requires 6 seconds to run from 80 l/s to 100 l/s.
Constancy
The constancy parameter represents the period during which the FlowShark Pulse
will retain and output (via Analog Output) the last valid reading before registering
zero (e.g., due to a temporary sensor obstruction).

Due to the card’s storage cycle restrictions (approximately 100,000 writing events),
the FlowShark Pulse only saves incoming data on the card on an hourly basis. This
interval is pre-set through the internal system time. Two exceptions include very
high data density and a cumulative data volume of approximately 3000 – 4000 bytes.
Data is saved in a standard text file format under the following filename: [name of

The absence of a reading (------ ) in a measurement window indicates that flow
velocity currently is not available for measurement in the associated window. This
may occur when the water is very clear or vorticity exists within the area. This also
may occur with low flow depths, such as approximately 13.78 inches (35 cm), where
8-62 ADS FlowShark Pulse O&M Manual
the FlowShark Pulse automatically reduces the number of measurement windows
available. The unit does not require as many measurement windows when low flow
depths exist.
The failure of one or more windows does not determine measurement success.
However, ADS recommends investigating the location if more than 50 percent of the
measurement windows fail (except under low flow conditions). When necessary,
please contact ADS for diagnostic support.

When level measurement from bottom up has been selected, the depth level and
signal quality for the returned echo will display. When external depth measurement
devices are in use, only the input signal (mA) for a sensor is available.
The signal quality level should be around 90 to 100 percent. Therefore, a depth
measurement with a signal quality falling below 50 percent will be rejected,
producing a 0 reading.

Calibration and Calculation Menu (CAL)
CAL Menu: Level
This menu allows the user to calibrate depth sensors against actual field
measurements by automatically modifying sensor mounting heights, adapt analog
outputs to the corresponding systems, and emulate relay switching events and analog
outputs. An option to enable and/or modify the automatic velocity calculation
function (when depth falls below the minimum depth required for velocity
measurement) also is available.
Figure 8-112 Menu selection
When using a combi sensor with the pressure measurement cell to measure depth, the
pressure measurement cell, based on its design, may experience zero point drift over
an extended period of time (refer to Chapter 3, Overview and Specifications).
Therefore, calibrate the pressure sensor to the zero point on a regular basis. ADS
recommends calibrating the sensor every 6 months. Analyze measurements taken
with the sensor out of the flow or in as shallow flow as possible.
Manually measure the depth levels thoroughly before calibrating the sensor (i.e.,
adjusting mounting height) according to another reliable measurement method or
device (e.g., value = 0, if the sensor has been removed from the flow).
The current depth level and range of fluctuation, including minimum and maximum
values, measured by the sensor will display while this window is open. This will
allow the user to determine the stability of flow depth conditions (e.g., surface
roughness). The best results are obtained under conditions where little variation
exists between the minimum and maximum values. Accept the current depth by
clicking on the (Enter) key.
Enter the manual (field-confirmed) value in the reference field on the next menu.

Determining the zero point for the pressure measurement cell often
involves measuring the current depth level using a yardstick, a ruler,
or another similar device without removing the sensor from the flow.
This method, however, can produce errors. Inserting the ruler (or
yardstick) into the flow can create a surge leading to erroneous
measurements depending on the current flow velocity.
CAL Menu: Velocity
Based on the continuous profiling technology employed, velocity typically does not
require calibration. However, under unusual site conditions where velocity requires
constant adjustment, contact ADS for assistance in performing calibrations.
When flow falls below the minimum depth required for proper operation of the
velocity sensor, (i.e., only 2.2 inches of flow exists between the water ultrasonic
sensor face and the flow surface or a total depth of 2.6 inches of flow exists when the
bottom plate of the sensor is at the bottom of the channel), use an automatic
estimation (auto calculation) of velocity. Use this function for computing very low
flow velocities under low depth conditions, such as unusually low minimum nightly
flows. Do not implement this function at locations that experience backwater
conditions.
Make sure that obtaining reliable depth measurements down to 0 is possible through
an independent, external depth measurement device (e.g., an air-ultrasonic sensor).
With falling depth levels, at some point it may no longer be possible to measure flow
velocity. When depths reach this designated minimum level, h_crit (critical level, the
lowest level at which flow velocity can be measured reliably), the FlowShark Pulse
will create an internal table of Q & V vs h values using the last valid flow velocity
reading before dropping below this critical depth. This table of values enables flow
calculations to continue, even when velocity measurements are not available, by
assigning an estimated velocity to a corresponding depth level (based on the
Manning-Strickler relationship). The unit automatically will compensate for the
shape of the pipe in the curve.
The erroneous measurements that develop from using this method in
the context of unstable hydraulic conditions may be significantly
greater than the errors that arise from measuring the actual flow
velocity and depth levels.
This method is suitable only for very low flow volumes that are
backwater-free.
8-70 ADS FlowShark Pulse O&M Manual
Figure 8-117 Calculation – submenu
min. + max. value
This parameter defines the range within which the FlowShark Pulse will measure and
process flow velocity.
Set the minimum value below zero only when negative readings are
expected. It is impossible to measure and to record negative velocity
readings during negative flows if the minimum setting is 0.
Velocity h_crit
This table represents either the latest values obtained from depth and corresponding
velocity measurements or preset values (i.e., default values of 2.6 inches for h-critical
and zero for v-critical). If a reasonably reliable estimate of velocity is available at the
critical depth, enter this estimate as v-critical. Otherwise, the system will apply
values from the Manning-Strickler table to estimate the corresponding velocity when
depth drops below h-critical while the auto calculation function is in use (set to yes).
See Auto Calculation on page 8-71.
Leaving the default v-critical value at zero with the auto calculation function
disabled (set to no) will drop velocity to zero when depth is below h-critical.

Auto Calculation
Selecting automatic YES from the auto calibration menu automatically updates the
Manning-Strickler table based on the last valid velocity value before depth drops

original, uncompressed format or as a compressed .zip file. Use a file utility, such as
WinZip®, to extract the file from the .zip file.
Using the .zip format reduces the file size by approximately 75 percent and, therefore,
ADS recommends using this format.
Refer to Chapter 8, Parameter Settings, for more information on the FlowShark Pulse
file structure and using the individual files.
The user cannot transfer data files if the memory card is not
installed and the storage capability is disabled.

Deleting Data Files
Delete a specific file by clicking the red delete link corresponding to the file (Figure
10-4). To save this file for viewing or to transmit the file at another time, the file will
be moved into a backup folder. If a backup folder does not already exist, it will be
created automatically. Files that have been transferred to this folder can be
permanently removed from the memory card by deleting the file from the backup
directory.
Figure 10-4 Contents of backup folder created
Data files that have not been deleted or moved to the backup folder
will continue to receive all future readings. This will dramatically
increase the size of the file because older, duplicate data will be
transmitted and saved to the file again.
Deleting a file (moving it into the backup folder) while a file of the
same name exists in the target folder will cause the older file to be
overwritten without warning.

Viewing Data
Clicking the Trend link on the left side of the screen displays a trend graph similar to
the trend screen displayed on the FlowShark Pulse. This graph displays up to 90 days
of the data stored in the unit memory. The following screen (Figure 10-5) offers an
example of this graph.
Figure 10-5 Online trend graph
Flow volume, depth level, average flow velocity, and water temperature display in
color on the graph. The units on the graph reflect the units designated on the
FlowShark Pulse display.
The readings on the y-axis are scaled at intervals of 0.1, 0.2, 0.5, 1, 2, 5, 10 ..... up to
10000. For this example, the selected scaling unit represents a horizontal line on the
grid.
Set the starting date and time for the trend graph in the Date and Time fields and set
the resolution (scale of the time axis) for the graph in the Res field. Choose from the
following options: 10 minutes, 1 hour, 6 hours, or 24 hours per grid line.
Click on the Update button to refresh the graph with new measurement data as it is
collected.
If the selected start date/time for the graph is the current date/time or
the time axis range allows the user to view a larger range than
selected for the start date/time and resolution, the graph will include
data that is older than the start date/time selected.

Materials and Chemical Resistance
Sensor construction involves the following materials:
z
Stainless steel V4A (ground plate or pipe sensor jacket)
z
PPO GF30 (sensor body)
z
PEEK (sensor crystal cover)
z
Polyurethane (cable sheath and glands)
Sensors with the pressure measurement cell include the following materials:
z
Hastelloy C276
z
Viton (PA/PR)
The sensors are resistant to wastewater, dirt, and rainwater. While the sensors do not
experience damage from the wastewater exiting most industrial plants, the sensors are
not resistant to all substances and mixtures.
In general, damage to the sensor may occur from chloride media
(corrodes stainless steel ground plate or sensor jacket), hydrogen
sulphide (H2S – decays copper wires and conductor paths from
diffusion through cable sheath or sensor body), and various
organic solvents (dissolves cable sheath or sensor body).
Individual substances may not adversely affect a sensor. However, under certain
circumstances, the combination of several of these substances could adversely affect
a sensor. Due to the unlimited number of possible combinations of substances, it is
impossible to determine the impact on a sensor from combining these substances.
Contact ADS representative to request free sample materials for long-term testing
purposes.
For special applications involving highly destructive or solvent-containing media,
Hastelloy or titanium ground plates are available for sensors made of PEEK. Pipe
sensors composed of highly resistant steel also are available. A special FEP coating
that is resistant to organic solvents or hydrogen sulphide is available for sensor cables
that will be immersed in the following highly corrosive, destructive media:
