2 Ultrasonic Flowmeter Series 6 gas flow meter
2.1 General
The Ultrasonic Flowmeter Series 6 is a sophisticated, multi-path ultrasonic gas flow meter
manufactured by Elster NV/SA. It has been specifically designed for custody transfer
measuring applications that demand a high degree of accuracy and reliability.
2.2 Applicable standards
The Ultrasonic Flowmeter Series 6 is manufactured to be in accordance with European
Directives: ATEX, PED, EMC and optionally MID.
If the meter is ordered for use at a location where European Directives are NOT mandatory,
the meter can alternatively be manufactured with IECEx or FM approval for use in
hazardous area.
2.3 Configuration
On the flow cell of an Ultrasonic Flowmeter Series 6 several pairs of transducers are
mounted. Each pair of transducers represents one individual measuring path. There are two
measuring path types on the Ultrasonic Flowmeter Series 6: Axial (single bounce) and swirl
(double bounce) these are shown in Figure 1.
Figure 1: Path types
The Q.Sonic
plus
path layout consists of 2 axial paths and 4 swirl paths. This combination
results in a complete symmetrical path layout, ensuring the most optimal accuracy. Figure 2
shows the path layout of the Q.Sonic
plus

2.4 Calibration
When using the Ultrasonic Flowmeter Series 6, model Q.Sonic
plus
in custody transfer
applications, most countries demand (by law) a calibration from a certified calibration
institute, supervised by an inspector of weights and measures. Examples of facilities
generally used for calibrations are Euroloop in Rotterdam (NL), TransCanada Calibrations
in Canada and PIGSAR GH45 of E.ON Ruhrgas AG in Dorsten (D).
If the Q.Sonic Series 6 has to be in accordance with MID, extra restrictions should be taken
into account (see chapter 9.4).

3 Theory of operation
An ultrasonic flow meter is an inferential measurement device that consists of ultrasonic
transducers that are typically located along a pipe's wall. The transducers are inserted into the
piping using a gas tight mechanism. Ultrasonic pulses are alternately transmitted by one
transducer and received by the other one. Figure 3 shows a simple geometry of two transducers,
‘A’ and ‘B’, at a sharp angle “ϕ” with respect to the axis of a straight cylindrical pipe with diameter
“D”. The Q.Sonic Series 6 employs reflection paths, where the acoustic pulses reflect one or more
times off the pipe wall.

Figure 3: Ultrasonic measuring line
3.1 Flow velocity measurement
The acoustic pulses are crossing the pipe like a ferryman crossing a river. Without flow,
they propagate with the same speed in both directions. If the gas in the pipe has a flow
velocity different from zero, pulses travelling downstream with the flow will move faster,
while those travelling upstream against the flow will move slower. Thus, the downstream
travel times “tab“ will be shorter, while the upstream ones “tba“ will be longer as compared
when the gas is not moving. Equation 1 illustrates the computation of these times:

ϕn the angle between the gas flow and ultrasonic signal.
The raw gas velocity is corrected by a Reynolds flow profile correction. This correction is
depending on the path type. Also the contribution of the gas velocity of each path to the
combined gas velocity is depending on the path type.

4 System description
4.1 Flow cell
The flow cell is the part of the Ultrasonic Flowmeter Series 6 that is mounted in the piping
system. All components making the Ultrasonic Flowmeter Series 6 (SPU, transducers, type
plates and optional pressure and temperature sensors) are mounted on the flow cell, see
Figure 4.
Figure 4: Example of an Elster-Instromet Ultrasonic gas flowmeter
4.2 Signal processing unit
The SPU is mounted in an explosion proof housing. The box consists of two separate
compartments; a main and a rear compartment (see Figure 5).
The main compartment can be opened from the side of the SPU and contains the main
circuit boards. The main compartment also comprises intrinsically safe connections for the
ultrasonic transducers and optional temperature and pressure sensors. All data processing
from excitation of the transducers to calculating the flow rate is handled by the electronics in
this compartment.
To prevent the box from opening by vibration, the covers on the side need to be firmly
tightened and secured with the lock screw in the cover, see Figure 6. When closing the
back compartment ensure all screws are used.
A grounding point is foreseen at the bottom of the SPU. As the meter is already internally
grounding, it is not necessary to use this grounding for normal operation.

Figure 6: SPU cover
The rear compartment comprises a field terminal board used for connecting the Ultrasonic
Flowmeter Series 6 to the end users applications. For detailed information about this see
chapter 5.2.2.
4.3 Transducers
The ultrasonic signals required for the flow measurement are generated and received by
ultrasonic transducers.
Piezoelectric transducers employ crystals or ceramics that are set into vibration when an
alternating voltage is applied to the piezoelectric element. The vibrating element generates
sound waves in the gas. Since the piezoelectric effect is reversible, the element will
become electrically polarised and produce voltages related to the mechanical strain, when
the crystal is distorted by the action of incident sound waves. Because the acoustic
impedance of the gas is much smaller compared to the acoustic impedance of the
piezoelectric element, and to maximise the acoustic efficiency, a matching layer is
employed between the gas and the piezoelectric element.
The transducers used in the Ultrasonic Flowmeter Series 6 are type ‘NG’, see Figure 7.
Figure 8 visualises the NG transducer with the mounting bracket.

5 Installation and commissioning
5.1 Introduction
It is very important to check the shipment of your ultrasonic flow meter equipment. At least
a visual inspection of surfaces and flanges should be performed. In case of damage,
contact Elster NV/SA immediately.
Also verify if all the necessary documentation is available as well. At least you should have:
• Safety instructions (doc. Code: 22.100.200.001.02/2 latest valid version)
• Operation and maintenance manual (doc. Code: 22.100.200.002.02/2 latest valid
revision)
Also look at your project data to see if extra documentation is required and delivered. If
documentation is missing, contact Elster NV/SA or your local agent immediately.
5.2 Installation requirements flow cell
5.2.1. Installing meter in pipeline
The Ultrasonic Flowmeter Series 6 (flow cell, transducers and SPU) is shipped in a suitable
box (e.g. wooden box, cardboard box, …). Carefully disassemble the box. Remove the
transport straps from the flow cell, and then move the ultrasonic flow meter (using the lifting
lugs provided on the flow cell) to the installation site. Install the meter according to end-
user’s company regulations and applicable local and national requirements. To ensure
optimal performance of the UFM, comply with the up- and downstream spool requirements
specified for your particular UFM (see your order documentation).
Warning!
To avoid possible injury, make sure the lifting equipment is suitable
for the weight of the Ultrasonic Flowmeter Series 6. Always use the
lifting lugs and make sure lifting equipment is certified and shows
no damage or wear.
Be aware!
• Special attention needs to be taken when the Ultrasonic
Flowmeter Series 6 has to be installed in accordance with MID
(see chapter 9.5).
• For FM Approved Ultrasonic Flowmeter see also the Control
drawing and installation remarks in the Safety instructions (doc.
Code: 22.100.200.001.02/2 latest valid version).

5.2.2. Testing installation
The flowcell is always hydrotested in-house at the correct hydrotest pressure before the
transducers were installed on the ultrasonic flowmeter. Herewith all welding of the flowcell is
checked. When an Ultrasonic flowmeter series 6 is installed in a pipe line, it is no longer
possible to hydrotest the pipeline. Water can be trapped between the housing and the
transducers, causing the meter to have difficulties measuring.
Before pressurizing check all pressure points on the meter. If necessary remove the cover
caps to have a clear view of the entire pressure point, particularly when an adapter is fitted
on the meter body.
5.3 Wiring instructions
All detailed information about wiring is stated the ‘Ultrasonic Flowmeter Series 6 Wiring
Instructions’ (document code 03.302.101.003.07/2), as well as Ultrasonic Flowmeter Series
6 Safety Instructions (document code 22.100.200.001.02/2). Please refer to these
documents for correct wiring of the Ultrasonic flowmeter series 6.
5.4 SPU configuration
When the meter is installed and correctly wired, it’s advisable to read out the parameter
settings of the meter. If the meter had been calibrated before, the parameter set-up should
be compared to the one of the calibration.
The parameter set-up can be read with the software package ‘SonicExplorer’. Connection
should be made through the Ethernet or DSL communication, more detailed information
about this matter can be found in the manual of the software packages. When mismatches
are detected; contact Elster NV/SA or your local representative immediately.
Warning!
When opening the SPU (either main – or rear compartment), obey the
rules and regulations that apply to hazardous area operations.
The electronics and the main plate of the UFM should be sealed. The sealing should be
done by either the calibration facility or by Elster NV/SA. This should be done according to
chapter 4.7; any mismatch has to be reported to Elster NV/SA or your local representative
immediately.
5.5 Cold commissioning
During cold commissioning the meter is pressurized with a known gas composition, at a
known temperature and pressure, because in some cases the UFM will not be able to
measure under atmospheric conditions.
A thorough functional test is performed by means of a PC and diagnostic software package
(‘SonicExplorer’). Diagnostics and status per measuring path and the zero flow can be
checked, assuming there is sufficient pressure in the meter. A technician of Elster NV/SA
will, if this has been agreed, verify measurements and check the system performance.

5.6 Hot commissioning
The hot commissioning is in most cases the last test of the UFM and can be witnessed by a
representative of the client and, if required, by an inspector of weights and measures for the
official sealing. Under this condition there is process gas in the pipe and a flow test is being
performed. The performance, AGC Levels/Limits and zero flow are checked again. If
possible, the gas flow running through the UFM will be compared to another flowmeter in
the line. Most UFM are calibrated gas flow meters, so the measured value is reliable
without exception. Furthermore, the interaction with the flow computer can be tested.

7 Maintenance, service and repair
7.1 Introduction
The Ultrasonic Flowmeter Series 6 ultrasonic gas flow meter contains no moving parts. The
transducers and internal pressure sensor are the only components that are in contact with
the gas medium. The materials used for the transducers are selected for the measuring
conditions that were clearly specified for the instrument. As a result the transducers and the
electronics are virtually maintenance free. However, Elster NV/SA recommends inspection
of the Ultrasonic Flowmeter Series 6 with the software packages ‘SonicExplorer’ at regular
intervals (e.g. monthly). In case of degradation of the meter, appropriate measures can be
taken on time.
For detailed information about maintenance, please refer to operation and maintenance
manual (doc. code: 22.100.200.002.02/2 last valid revision).
7.2 Exchanging components
Different parts of the Ultrasonic Flowmeter Series 6 metering system like transducers,
electronic boards, etc can be exchanged easily. The digital programmed pulse shape and
pulse identification of the meter is always identical. Therefore the electronic- and transducer
products need no adjustment. This means that re-programming or re-calibration of the
meter after exchanging any identical part of the Ultrasonic Flowmeter Series 6 metering
system is not necessary.
Spare parts of the Ultrasonic Flowmeter Series 6 metering system must be supplied by
Elster NV/SA. After exchanging parts of the Q.Sonic Series 6 metering system the present
“calibration” sealing must be renewed, see the chapter 4.7.
Caution!
Before exchanging any components verify with your local
metrology authority on proper procedures. It may be required that
the operation needs to be witnessed by a representative of the
local authority.
Warning!
Exchanging of components should only be done with the same
type and model; unless otherwise specified by Elster NV/SA.
7.2.1. Pressure sensors exchange
The meter might be equipped with an optional pressure sensor for internal use (see
chapters 4.4). As the pressure sensors are specially designed for the Ultrasonic Flowmeter
Series 6, they may only be exchanged with sensors from Elster NV/SA.

22.100.200.000.02_2_B ULTRASONIC FLOWMETER SERIES 6.DOC
Warning!
For the pressure sensor it’s absolutely necessary to depressurize
the line before exchanging.
7.2.2. Temperature sensors exchange
The meter might be equipped with an optional temperature sensor for internal use (see
chapters 4.5). As the temperature sensors are specially designed for the Ultrasonic
Flowmeter Series 6, they may only be exchanged with sensors from Elster NV/SA.
As the temperature sensor only measures the flow cell temperature and is not in contact
with the gas in the pipe, exchanging can be done under pressure.
7.2.3. Transducer exchange
Each transducer is a separate component of the Ultrasonic Flowmeter Series 6 that can be
exchanged independently. This can be done without degradation of the measuring
properties and accuracy (thus the calibration) of the Ultrasonic Gas Flow Meter.
However, as the transducers are paired up during production, Elster NV/SA always
recommends changing both transducers of an acoustic path, if possible.
Warning!
Obey the rules and regulations that apply to hazardous area
operations and those with respect to custody transfer regulations
(sealing).
Exchanging a transducer can take place when the line with the Ultrasonic
Flowmeter Series 6 is depressurized:
Refer to specific installation instructions delivered with the
transducers: Transducer exchange at atmospheric conditions
(Document code: 03.200.001.001.02/2 last valid revision).
Optionally exchanging a transducer can be done when the Ultrasonic
Flowmeter Series 6 is pressurized:
A special tool is required for this: the ‘retraction tool NG transducers’.
Please familiarise yourself with the documentation regarding this
special tool: Retraction tool NG transducers (document code:
03.203.101.001.02/2 last valid revision).
Before beginning this procedure please verify if this is allowed by the
safety standards set by your company and local safety regulations. If
in doubt, DO NOT remove the transducers under pressure.
7.2.4. SPU exchange
Parts of the SPU can be exchanged without problems, provided that the appropriate
hardware and software versions are used. The product numbers can be found on the PCB
and have following structure xxx-xxx-xxx-xxx. The software version and its checksums can
be checked through the front panel (see chapter 6.1).
