• installation of the cabling between the electronics and the transducers complying with
enhanced safety
enhanced safety requirements according to IEC 60079-7.
enhanced safetyenhanced safety
The flowmeter consists of a meter body with one or two (twin meter) electronic units installed on
top of it.
For smaller diameters the meter body is fully machined hence no welding is done.
For larger diameters the meter body is a welded construction.

Page 12
2 DEVICE DESCRIPTION
A series of acoustic transducer are installed on the inside of the meter body. Each pair of
ultrasonic transducers forms an acoustic measurement path. The acoustic measurement path
consists of one (direct) chord or two (reflective) chords.
The chords in the horizontal plane are used for flow measurement, the chords in the vertical
plane are used for diagnostics only. The reflective chords that are offset from the meter’s centre
line use acoustic mirrors to reflect the ultrasonic signal. The reflective chords that are in the
centre line of the meter reflect directly on the pipe wall. Direct chords do not reflect and
therefore do not require acoustic mirrors.
The transducers are electrically connected to the electronic unit on top of the meter by means of
coaxial cables. The cabling is protected against mechanical damage and moisture by means of
covers. The coaxial cables enter the electronics enclosure through its “foot” (or support). In this
foot an Ex d approved cable feed through is installed that closes this entry to the electronics
enclosure.
On the other side the coax cables are connected to the transducers, this connection is also done
by an Ex d approved connector
ALTOSONIC V12
Figure 2-2: Location of sensors and electronic unit
2.2.1 Transducers
Acoustic signals are transmitted and received by means of ultrasonic transducers. The active
part of an ultrasonic transducer is a small disk of piëzo electric ceramic in the front of the
transducer. It is packaged (sealed) in a construction of metal parts and high grade epoxy or
inside a titanium housing. The front side of the transducer is exposed to the gas to be measured,
this results in the best efficiency for transmitting and receiving ultrasound.

DANGER!
The transducers have an Ex-d socket (socket, 3) that connects to an Ex-d plug 4 which
terminates a coaxial wire 8.
An alignment pin 5 on the connector engages with a slot in the Ex-d socket 2, this ensures that
the transducer is connected with the correct polarity. The cap 6, screwed on the Ex-d socket,
fastens the connector, a small securing screw (M2) 7 secures this cap. The transducers are
fastened in the meter body using a transducer nut with a hole in the centre 9. A double O-ring
1 seals the pressure inside the piping effectively from the outside world.
2.2.2 The electronic unit
The housing consists of three compartments. Each compartment has a removable cover that
gives access to the inside, in order to connect external wiring or to install or to replace
components.

Connection compartment
The compartment on the right side is the connection compartment, which contains only a block
with screw terminals. Signal wires from and to the electronics compartment are connected to
this terminal block. Wiring to other (external/auxiliary) equipment can be connected to the screw
terminals in this compartment.
Cables can enter this compartment through cable glands installed in either one of three
threaded holes M20x1.5.
DANGER!
Unused holes must be closed with Ex d approved blind stops.
Power supply / RS485 compartment
The compartment on the left side is used to install the power converter. This board also includes
two serial data ports (RS485). As an option an additional diagnostics processor board can be
installed. Wiring to external equipment or to a power source is attached to connectors with
screw terminals. These connectors engage directly with matching parts on the printed cicuit
boards.
Cables can enter this compartment through cable glands installed in either one of three
threaded holes M20x1.5.

Electronics compartment
The compartment on the front has a cover with a glass window. It contains a frame with a
number of printed circuit boards. The boards have the following functions:
• Frequency and status output board
• Processor boards
• Sensor driver board
• Display module (connected tot the front side of the frame, can be seen through the cover with
the glass window)
2.3 Software description
The ALTOSONIC V12 contains a powerful microprocessor that controls the functions and
calculations it performs. The microprocessor executes program code consisting of several
modules, according to the functions it has to perform. By means of a set of parameters the
software can be configured to various sizes and models of flowmeters and according to specific
requirements depending of applications or customers.
ALTOSONIC V12
LEGAL NOTICE!
The parameters are stored in a configuration file. Configuration parameters are password
protected in order to prevent unauthorized modification. Access in order to read, view and
inspect parameter values is unrestricted.
Individual parameters are classified according to “roles” in order to define differentiated access
rights. Each “role” is associated with a “typical” user or operator having specific responsibilities
or duties. Users have to be registered with a user name and a password, when registered the
role of the user is also defined, and by consequence also the access rights of that user.
The following roles have been defined, listed in according to the rank in the hierarchy.
Roles and authorisation
Developer restricted to KROHNE R&D employees.
Factory restricted to KROHNE factory employees, to implement factory settings in the
Service restricted to authorized service personnel, to the discretion of KROHNE.
Calibrator restricted to personnel acting on behalf of a legal calibration station.
Supervisor restricted to personnel acting on behalf of the owner/operator of
Operator restricted to personnel acting on behalf of the owner/ operator of the meter (for day
meter.
the meter (administrator function), to the discretion of the owner/operator of the
meter.
to day operation), to the discretion of the owner/operator of the meter.
14
Only a higher rank user can register a lower rank user. Users can have the same rank.
In addition to restrictions depending of the defined role of a user, a physical “overwrite disable”
contact / jumper protects the configuration parameters. This disables any user from making
modifications to parameters that would influence the measured flow or volume value. This
prevents unintentional or unauthorized changes to the parameters and possibly invalidation of
the calibration.

Normally the meter is delivered with a set of parameters suitable for the application.
In case a modification of the configuration file is made, this is stored in its data logging memory.
This information can be retrieved afterwards for auditing and verification purposes.

Make sure that the extensions on the bottom of the flanges are in good order to prevent the
meter from rolling over. Otherwise take appropriate measures to prevent the meter from rolling
over.
Storage conditions
Maintain the following storage conditions to prevent the equipment from corrosion or early
failure:
• Humidity: <95 % RH (closed and heated storage area)
• Storage temperature: -40...+65º C / -40...+149º F
• Avoid direct solar radiation during long storage periods, store under a sunshade
How to prevent corrosion
Pay attention to the conservation of the inner pipe wall, especially for carbon steel meters.
Typical applications such as measuring dry natural gas (sales quality) or natural gas with a
corrosion inhibitor do not require an anti corrosion coating inside the meter tube. A coating can
even be regarded as unwanted because it may wear off, which will have an impact (although
minor) on the accuracy.

3 INSTALLATION
However for storage and/or transportation additional protective measures are recommended.
Depending on how long the protection should last one of several methods can be considered:
1. For a storage period of less than one year, the inner pipewall should be protected by a corrosion
inhibitor such as Shell Ensys.
Do not apply the corrosion inhibitor on the acoustic transducers.
2. For a period of a year or longer, the pipewall should be protected by Tectyl or a similar product.
Do not apply Tectyl on the acoustic transducers.
3. Independend of the storage period, the inner pipewall can be protected by an oxygen free envi-
ronment. This can be created by mounting blind flanges, using a vacuum pump to remove the
air and subsequently filling the meter with nitrogen. It is recommended to place some bags of
silica gel inside the flowmeter. To protect against corrosion, the humidity should be less than
38% and/or oxygen should not be present. Special regulations may be applicable for transportation and storage of a pressurised flowmeter.
3.3 Transport
WARNING!
•
Even smaller size flowmeters have a considerable weight. Check the weight of your
flowmeter in order to select suitable means for transportation and lifting.
•
Use appropriate materials such as chains or hoisting straps that are in good condition.
•
Use the eye bolts on the meter body to attach chains or straps to lift the meter (if not present:
check condition of the threaded holes on the flanges and if okay screw eye bolts in the
threaded holes).
•
Never lift the meter using the converter housing to attach straps.
•
In case a fork lift will be used make sure that the flowmeter is secured against rolling off the
forks, or against straps sliding off the forks.
•
Verify local safety regulations, directives and company procedures with respect to hoisting,
rigging and transportation of (heavy) equipment.

3.4 Pre-installation requirements
INFORMATION!
The equipment is designed for safe operation under conditions according to the following
classifications:
•
Pollution degree 2: this means that normally only nonconductive (dry) pollution will occur.
Temporary conductivity caused by condensation can occur.
•
Protection class I: this means the equipment must be earthed.
•
Humidity: <95% RH
•
Ambient temperature: -40...+65°C / -40...+149°F
•
Suitable for indoor and outdoor use.
•
IP66 / NEMA 4X classification.
CAUTION!
The flowmeter should be protected from corrosive chemicals or gases and dust or particles
accumulation.
CAUTION!
Do not intend to perform a hydrostatic test of the installed flowmeter.
INSTALLATION 3
The flowmeter has been hydrostatically tested during manufacturing (see reports) and must not
be retested with the ultrasonic sensors installed. Water will protude in the sensor pockets and
remain. This will create acoustic shortcuts and possibly cause the flowmeter to start operating
in failure.
3.5 Installation
3.5.1 Mounting position
Install the ultrasonic gas flowmeter in horizontal position with the flow arrow indicator on the
nameplate or on the meter body in the direction of the positive (forward) gas flow.
Make sure that the converter is on top of the flowmeter after the installation.
Check the weight of the meter. Typically the weight of the meter will be considerably more than
the same length of pipe line.
To support the meter additional supports might be needed, preferably two, one on either side of
the meter.
Always support the meter at its flanges, the weight of the meter shall never rest on the case
around the transducers and the cabling.
If supports can not be placed under the meter flanges, supports may be placed under the mating
flanges of the pipeline. If supports can only be placed under the pipeline sections upstream or
downstream of the meter, these supports shall be as close as possible to the meter. In this case
a calculation must be made to verify that the load on the pipeline will not exceed acceptable
values.
The meter should be installed in the pipe line with gaskets, nuts and bolts according to the type
and size of the flanges of the gas flowmeter. The flanges of the meter should match with the
flanges of the pipeline where the meter should be installed.
Make sure that the gaskets do not protude into the flow as this can reduce the accuracy of the
flowmeter.
www.krohne.com04/2013 - 4002643502 - MA ALTOSONIC V12 R02 en
19
Page 20
3 INSTALLATION
In order to install the gas flowmeter, the pipeline must have a slot of such length that the meter
including the gaskets fits nicely in the slot. It should not be necessary to use excessive force to
tighten the bolts in order to close the gaps on either side of the meter.
Nor should the slot be too small, implying the slot has to be widened by applying brute force to fit
the meter and gaskets in the slot.
For tightening the bolts of the flanges, apply a lubricant as required, in accordance with the
materials as used and applicable standards.
Tighten the bolts of the flanges with a torque according to the standards applicable to the
flanges and materials used.
3.5.2 Pipe diameters and lengths
Make sure that the inner diameter of upstream and downstream pipes matches the specified
connection diameter of the ultrasonic flowmeter within 1%. Contact KROHNE if the iner diameter
deviates more than 1%.
ALTOSONIC V12
3.5.3 Flow conditioners
Although the flowmeter is a highly accurate device, an additional flow conditioner can be
installed upstream of the flowmeter in order to minimize measuring uncertainty, in particular
when a strongly distorted flow velocity profile has to be expected, or when the available space for
a metering run is critical. If a flow conditioner is used the total inlet length may be reduced to
only 5 DN: having 2 DN upstream of the flow conditioner and 3 DN in between the flow
conditioner and the flowmeter.
INFORMATION!
•
Preferred model is the “perforated plate” type. A “pipe bundle” type of flow conditioner is not
recommended.
•
When a flow conditioner is included in the metering run, it is strongly advised to use the same
flow conditioner and inlet pipe configuration during a flow (wet) calibration (see e.g. ISO17089
or AGA-9 for detailed requirements).

INFORMATION!
Contact KROHNE for recommendations on bi-directional use.
3.5.5 Control valves
CAUTION!
Under circumstances ultrasonic gas flowmeters can suffer from interference from noise
generated by pressure control valves (PCV). In case the frequency spectrum of the PCV-noise
extends in the range of the operation frequency of the ultrasonic transducers and the strength of
the noise results in a signal to noise ratio smaller than the critical value, the ultrasonic
flowmeter will not be able to operate. Consult the manufacturer for advice in case a PCV with
high pressure cut will be operated close to the ultrasonic flowmeter.

INFORMATION!
•
See ISO 17089 for further details.
•
Use a PT 100 element with thermowell and transmitter as temperature transmitter.
Preferably use tapered thermowells to avoid vibrations.
•
Connect the pressure transmitter to the Pr-point in the meter body using an intermediate
isolation valve and/or valve manifold.
ALTOSONIC V12
CAUTION!
Either use a suitable blind plug or blind flange (and sealing as required) to blind the pressure
port, or a sense line should be connected in an appropriate way.
A sense line should be properly supported to avoid vibrations and to prevent the weight of the
sense line to apply a load on the connection at the pressure port.

7.4 Loading a monitoring configuration
INFORMATION!
There are two different methods to obtain data from a flowmeter.
•
Request information on a specific data item: if it is a parameter the current value will be
reported, this is a static value. If it is a variable, the value will be reported and updated every 2
seconds.
•
Define a selection of data that the flowmeter will send as a package and update at specific
rate. This way the data collecting process is customized to collect only those variables or data
elements that one really needs or wants to be monitored and / or logged (as the meter
produces a large amount of data it will not be possible to collect and update all the variables
in a short time interval).

7.9 Creating reports
The service tool has been developed to also enable you to create records regarding the state of
the ultrasonic flowmeter and the way the meter performs. Records can be printed reports or
records can be exported and saved as data files on a storage medium.
Records can be created regarding:
• the actual parameter values as present in the meter, governing the performance and
functionality of the meter
• process values as observed at a specific instant
• the Modbus address mapping regarding the parameters and process values that can be
retrieved from the meter using Modbus register addressing
• rights and/or restrictions regarding access to the ultrasonic meter and the functionality of
this service tool, as is available for a user of a specific category (such as operator, supervisor,
calibrator, service technician or factory authorized support engineer).

7.10 Logging data from a flowmeter
ALTOSONIC V12
After connecting with a flowmeter, the default monitoring configuration file included in the
“Quick Start” software package will start the logging process automatically. A predefined set of
data will be collected from the meter and stored as a file on disk.
A field in the status bar at the bottom of the screen will show a field displaying “Log.ON” with a
green background colour.
In the same field the name of the disk file where the data is stored is displayed between square
brackets.

Logged data will be stored in a file for each day (provided it is the same meter).
The software will automatically assign a name to file where the logged data will be stored, the
date will be part of the file name.
When the logging process is restarted - after it has been interrupted – the new data will be
appended to the same file as used before (assuming this will happen on the same day).
When a new day breaks a new log file will be created even while a logging process is running.
Logged data will be stored in a file with “.CSV” format.
By default, the file will be stored in the folder:
C:\KrohneData\Logging\MeterModel\Meters\MeterSerialNumber
SOFTWARE SERVICE TOOL 7
Some of the actions above or the way the service tool performs depend on specific settings. How
settings can influence the way the service tool works is explained in the next chapter.
7.11 Customizing the data logging process
As the meter produces a large amount of data, it is not possible to collect all data at a high rate.
Storing this amount of data would create log files of unpractical sizes.
Decide which data elements have to be collected and stored.
A first selection is already made when defining the set of data selected for the monitoring
process. The set of data to be saved in a log file on disk must be the same as selected for
monitoring or a subset thereof.
Another way to reduce the amount is implemented by means of a setting “Log Rate”. This is
either the same as the “Fetch Rate” (parameter value equal to 1) or it is a fraction of the “Fetch
rate” (integer parameter value 2..10).

7.12 Adjusting parameter settings
A typical adjustment of the parameter setting is the adjustment of the meter factor.
The meter factor is determined during the calibration and is programmed before the ultrasonic
flowmeter is sealed.
Adjustment of the meter factor for Custody Transfer (CT) applications can only be done under the
supervision of a calibration officer. A dedicated procedure for calibration adjustment and
programming the meter is available from KROHNE on request.

8.1 Periodic maintenance
The ultrasonic gas flowmeter does not contain any moving parts. During operation no
maintenance will be required such as lubrication or replacing parts that wear out. Therefore
during normal operation there will be no need to disassemble the meter in order to gain access
to the inner parts of the meter.

It is however good practice to make a log file on regular basis, refer to
flowmeter
influences such as an overflow in a separator or a process failure in a gas treatment plant, may
cause a fouling of the meter which may result in deviations. By making a log file on regular basis
such a failure can be pinpointed in time, and as such the financial consequences can be correctly
adjusted. The ALTOSONIC V12 also has on board diagnostic features that will alert the operator
in case of malfunctioning. In a log file information will be stored with much more detail.

8.3 Exchange of transducers
Transducers are not likely to break down. In the unlikely situation that a transducer fails, the
transducer has to be replaced. Although not strictly required, it is common practice to replace
the other transducer on the same acoustic path at the same time.
If possible, depressurise the flowmeter. If this is not possible, use the extraction tool to remove
the transducer under pressure (maximum 150 bar(g)).
WARNING!
The ALTOSONIC V12 is a pressurised UFM. Do not remove transducer, bolts or other pressurised
parts without the garantuee that the meter is fully depressurised.
8.4 Exchange of transducers - Depressurised condition
DANGER!
Always read instructions for safe handling of the equipment and installations first.
Switch off the power supply to the meter and wait at least 1 minute before opening the Ex-d
enclosure. Advisable is also to use a gas detector in detecting possible hazardous environmental
conditions. Also during raining conditions make sure no water/rain can penetrate in the
electronic housing, same accounts for dusty environments.
It is preferred to disconnect power supply from the equipment by unscrewing the right lid of the
electronic housing . After disconnecting close lid fully and attach labels to switching gear to
prevent from unwanted switching on again.
The transducers are installed and fixed mechanically at a very precise manufactured position
inside the meter body. To access the transducer position that needs to be replaced use the
following instructions.

8.5 Exchange of transducers - Pressurised condition
WARNING!
The tool is designed to be able to replace a transducer of a ultrasonic gas flowmeter - while it is
pressurized - in a safe way. Nevertheless, working with equipment with high gas pressure
requires utmost care. Observe the following precautions:
•
Make sure that staff working with this tool are familiar with and act accordingly with laws and
regulations - especially regarding safety - applicable to the site or location where the job will
be performed.
•
Make sure that staff supposed to work with this tool are adequately trained and educated and
have sufficient knowledge of the tool and the way to use it. It is recommended to attend a
training session that can be offered by the manufacturer.
•
Check the availability of all materials that may be needed; make sure that, once started, the
operation can be finished with the proper installation of a new transducer; the procedure
should not be interrupted because of any kind of interference or put on hold for reason of
lacking parts or materials.
•
Before starting the operation check if the equipment (retraction tool, bolts, tools) is complete
and in good working order. In case one or more bolts are missing, make sure replacement
bolts are conform to grade (strength) 12.9 (according to DIN ISO 898/1).
•
During the procedure a small amount of gas will escape. Check if this may lead to any health
risk due to hazardous substances.
•
Provide means to detect potentially dangerous concentrations of hazardous gases. Take
measures to avoid breathing escaping gas anyhow.
•
Make sure that there is enough free room for a fully extracted retraction tool around the
flowmeter.
•
Take precautions to prevent vehicles (fork ligt, crane etc.) to come close to the retraction tool
while it is installed on a meter; the risk that the tool accidentally will be hit (and damaged) by
such transportation means must be eliminated.
•
Check if the electric power supply of the meter can be switched off (necessary for reasons of
explosion safety). If the electric power supply can not or should not be switched off: make
sure a gas detector is available, to verify the absence of hazardous atmosphere when
performing the retraction and replacement of a transducer.
•
Do not use the tool to sit on, to lean on or step on it when installed on the ultrasonic gas
flowmeter.
•
Do not leave the retraction tool unattended while it is installed on a meter and the operation
is in progress until the operation is finished.
SERVICE 8
CAUTION!
•
Make sure it has been properly diagnosed and identified which transducer(s) is (are) suspect
and may need to be replaced.
•
Make sure an electronic instrument for measuring resistance and capacitance is available,
check that it is recently calibrated and fitted with fresh batteries (or spare batteries are
available.

INFORMATION!
•
Whenever it is possible to isolate and depressurize an ultrasonic gas flowmeter in case it
would be necessary to replace one or more transducers, that should be the preferred way to
proceed instead of using the retraction tool.
•
Decide which persons need to be involved in the operation, especially the ones that have to
perform the job at the location of the meter, empower procedures to limit access to the area
where the operation takes place only to them.

8.5.2 Procedure to remove a transducer
Step 1: Locate the suspect transducer
• Locate the position of the suspect transducer on the meter body.
• Switch off the electric power supply to the gas flowmeter.
• Remove the cover as necessary to gain access to the suspect transducer and the signal cable
that connect to the transducer.
In case of a warning, a problem or a failure, a technician using the diagnostic tool that is
available for the ultrasonic gas flowmeter, will be able to identify the number of the acoustic
path that most likely causes the problem.
The transducers are identified with codes as: 1U, 1D, 2U ... 6D. The number refers to the acoustic
path number. A "U" refers to the upstream transducer and a "D" refers to the downstream
transducer of an acoustic path.
For an ALTOSONIC V12 six transducers (belonging to three acoustic paths) are located on one
side (front) of the flowmeter. The codes and locations of these transducers are indicated in the
figure below.

Step 3: Test the suspected transducer
INFORMATION!
Before starting the operation to replace a transducer care must be taken to make sure which
transducer is suspect to be failing. As a start the diagnostic tool to check the performance of the
ultrasonic gas flowmeter shall be used for this purpose. In case of doubt consult the local
support organisation of the manufacturer. Be aware transducers always operate as pairs
(belonging to the same acoustic path). Therefore, using this diagnostic tool it may not be certain
which one of a pair needs to be replaced.
Secondly the electrical capacitance and resistance of the suspect transducer can be measured
to identify which transducer of an acoustic path is suspect. An observation of a low resistance
value or a capacitance value deviating from specification can be a helpful confirmation for
identifying a transducer that may be failing.
The electronic measuring instrument is not supplied as part of the kit. It can be any instrument
suitable to measure a capacitance in the range of 0.1 ...1.0 nF and an electric resistance in the
range of 1 MΩ ... 20GΩ. This is a fairly common device and supposed to be available.
• Position the connector of the coax adapter cable in the connector in the transducer.
• Measure the electrical capacitance of the transducer. The value must be 0.32...0.34 nF.
• Measure the electrical resistance of the transducer. The value must be > 10 MΩ (typical value
= 1 GΩ).
• Release the adapter cable.

9.1 Measuring principle
The ultrasonic gas flowmeter operates according to the principle of measuring the transit time
of an ultrasonic sound wave. A gas velocity is derived from the difference in transit time of a
sound wave travelling in a direction with the flow direction and the sound wave travelling in the
opposite direction.
The trajectory of the sound wave is called the acoustic path. A chord is the direct path crossing
the pipe from one side to the opposite side. Using reflection, an acoustic path can consist of two
or more chords. The name ALTOSONIC V12 is related to its design where 12 chords build 6
acoustic paths.
9.2 Transit time measuring principle
ALTOSONIC V12
Figure 9-1: Transit time measuring principle
1 Direction of gas flow
2 Component of velocity in the direction of the chord
In a pipe section two transducers A and B create an acoustic path, which in the above figure, is a
single chord. This chord is the distance between transducer A and B and has a length L. The
chord intersects with the centre line of the pipe at an angle ϕ.
Both transducers are capable to transmit and receive an ultrasonic signal. First, one transducer
acts as a transmitter and the other as receiver, then the other way around. The transit time of an
ultrasonic signal along a measuring chord is influenced by the velocity of the gas flow (v). If the
gas flow is zero the transit time from transducer A to B is exactly the same as the transit time
from transducer B to A (determinded by the speed of sound in the gas).
When the gas flows with a velocity v and with c being the speed of sound in the gas:
v.cos(ϕ) is the component of velocity in the direction of the measurement chord.
This component increases or decreases the travel time (time of flight of an acoustic waveform)
as it moves from one transducer to the other transducer. The transit time from transducer A to B
) is:
(t
AB
98
In opposite direction from transducer B to A the transit time (t
www.krohne.com 04/2013 - 4002643502 - MA ALTOSONIC V12 R02 en
BA
) is:
Page 99
ALTOSONIC V12
The velocity of the gas is derived from formula (1) and (2) as:
An important feature of this method is that the calculated gas velocity does not depend on the
speed of sound in the gas or gas properties in general. The gas velocity as calculated is only a
function of the measured transit times t
intersection of the measuring chord are supposed to be known from the design of the flowmeter.
As a “bonus” the speed of sound in the gas can be derived from formula (1) and (2) as :
TECHNICAL DATA 9
and tBA; the length of the chord and the angle of
AB
This gives a measured speed of sound value, a valuable tool for diagnostic purposes, as it can be
compared with data from other sources.
9.3 Swirl compensation
At specific spots in the pipe, the local gas velocity vector may not be exactly parallel to the pipe
axis. This effect can be the result of a flow velocity pattern called swirl. This is a frequently
occurring velocity pattern where the gas mass in the pipe rotates as it flows. As an example, the
flow velocity pattern after a double out-of-plane bend is shown below.
Figure 9-2: Swirl pattern after a double out-of-plane bend
Another velocity pattern that frequently occurs, especially downstream of a single elbow or bend
in the pipeline, is shown in the picture below. There, just after the bend, the gas mass splits in
two contra rotating vortices.

99
Page 100
9 TECHNICAL DATA
Figure 9-3: Swirl pattern after a single bend
Swirl can disturb the gas velocity measurement as the tangential velocity component adds up
with the gas velocity measured along one chord. However chords can be arranged in a way to
compensate for swirl effects. Two chords arranged in the same plane intersect the flow at
opposite angles (cross configuration). These chords respond to the tangential velocity
component with the same magnitude but with the opposite sign.
This allows cancellation of the swirl effect by adding or averaging the measured velocity value of
both chords. An acoustic path with two chords in a V-shape, with a reflecting signal, has the
same effect. The measured flow velocity is increased by the tangential component on one chord
and decreased by the same value on the other chord.

With an ultrasonic measuring system the measured gas velocity value is the average velocity
sampled across the length of the acoustic path. Due to distortion of the gas velocity profile in the
pipe this value may not be representative for the average gas velocity across the whole of the
pipe cross section. In order to obtain a high accuracy the flow is sampled using a number of
measuring chords intersecting the flow in different planes, as shown in the figure below.
Figure 9-4: Path configuration with multiple acoustic paths
The total volume flow is calculated by means of an integration algorithm using the results from
the individual paths.
As swirl components are already compensated for in each individual measuring plane, the
integration method using data from multiple paths makes the flowmeter highly insensitive for
any kind of distortion of the flow profile.
The average speed of sound is the average of the speed of sound values measured on each of
the chords. Normally these values are very close to each other.
