Principles of Measurement
Depending on the gas flow rate the fiscal metering shall be divided into
three basic measuring principles:
Single line meter run with
check device using turbine
- For gas flow rates up to 15,000
Single line meter run using
ultrasonic meter and turbine
meter in series
- For gas flow rates over 20,000
Either of above principles, as
agreed by the Parties
- For gas flow rates from 15,000
Sm3/h to 20.000 Sm3/h
Every meter run consists of the following components, depending on
measuring principle:
• Measuring device for definition of flow rate
(gas meter like turbine meter, ultrasonic
• [Measuring device for definition of gas quality
(Gas Chromatograph)]
• Switch device between working and reserve
• Shut-off devices upstream and downstream
(Ball valves)
• Check device for gas meter
• Control device
• Communication device
• Applicable number of metering runs
• Pulsation / Vibration absorber (flow
straightening vanes)
• Electro technical devices
• Additional equipment
Single Line Meter Run with Check Device
This measuring principle is applicable for gas flow rates up to 15.000

General Requirements
The meters should be operated within the specific flow range and
operating conditions to achieve the desired accuracy and normal life
The requirements of accuracy, safety, economy, efficiency, traceability
and reliability shall be considered while designing the measurement
The metering runs shall be designed such that a single failure does not
shut down the whole measurement.
Engineering Units
Parameter Units
density kg / m3
energy MMBTU
mass kg
pipe diameter mm
pressure bar or Pa
temperature °C
velocity m/s
viscosity, absolute dynamic cP or Pa ·s
volume Sm3
volume flow rate Sm3 / h
Table 1: Engineering Units
An individual calibration of each meter shall be made prior to operation.
The results of this calibration shall be available on request, together with
a statement of conditions under which the calibration took place.
Meter Proving on Site
In the case of a single line meter run with check device, the meters shall
be proven by serial operation at least annually. In case of a single line
meter run using ultrasonic meter and turbine meter in series, the
differential between the two meters shall be monitored continuously.
Calibration Intervals
The calibration intervals shall be as follows:
Component Interval in
Turbine Meter [G 4000 and G 6000] with oil pump 16
Turbine Meter for custody transfer with
1. Qmax ≥ 3000 Sm3/h
2. with installation of a reference meter
3. possibility to connect both meters in series
4. reference measurement during start-up and annual
repetition of reference measurement
( Note: all four
conditions have to
be fulfilled)
Calorific value measuring device 1
Flow computer 5
Additional devices except indicators and switch devices 5
Additional switch devices and switch over devices unlimited
Table 2: Calibration Intervals
As far as the calibration approval defines a shorter period for calibration
than given in Table 2: Calibration Intervals then the shorter interval has
to be considered.
Maximum Permissible Error
The limit of maximum permissible error has to be defined as well for the
single gas meter as for the complete measuring device.
Within the measuring device the systematic error of one gas meter
should not be compensated by the contrarily systematic error of another
gas meter.
Regarding measurement uncertainty analysis Technical Report ISO/TR
5168 has to be taken into consideration.
Especially the INGL-requirements listed below have to be followed:
Flow rate
Maximum permission errors
on initial verification in service
Q ≤ 0.2 x Qmax ± 1% ± 2%
Q > 0.2 x Qmax ± 0.5% ± 1%
Appendix 4- Part B
Gas Quality Measurement
1. General
INGL is operating the Transmission System in order to transport gas for the
Shipper and Other Shippers from the Delivery Points to the Redelivery
Points, without being the owner of the gas transported. In order to protect the
Transmission System, the Shipper, and Other Shippers, INGL has
established a gas quality specification, which is set out as Appendix 2 of this
Agreement. This specification determines the maximum and minimum values
of certain components and parameters of the gas. In order to maintain this
quality, INGL shall carrying out quality measurements at certain points of the
o At the Delivery Points (which may be carried out by the
Upstream Operator on INGL's behalf)
o At the Redelivery Points
2. Quality Measurement at the Delivery Points
At the Delivery Points, two principle types of measurement will be carried out
o Online measurent
o Offline Measurement
2.1 Online Measurement
The Following properties will be measured online:
o Gas Composition (Calorific value)
Which will be measured with a Gas Chromatograph.
o Water Dew Point
Which will be measured by a moisture analyser
o Hydrocarbon Dewpoint
Which will be measured by a Hydrocarbon dewpoint analyser
o Hydrogen Sulphide
Which will be measured by a Sulphur analyser
2.2 Offline Measurement
The above online measurements shall be checked and verified by analytic
investigation of the gas in a laboratory, initially at monthly invervals. The gas
shall be taken by probes from dedicated points at each Delivery Points.
Further, this quality measurement procedure will also be used to determine
other components mentioned in Appendix 2, such as sulphur and sulphur
Upon conclusion by INGL, acting as a Reasonable and Prudent Operator,
that the gas quality is stable, the interval may be extented to maximum one
3 Quality Gas Measurement at the Redelivery Points
Since the Natural Gas transported in the Transmission System may be from
several sources, the gas composition (Calorific value) shall be measured at
each Redelivery Point (unless agreed otherwise by the Parties). This
measurement will be carried out by a gas chromatograph.
4 Calibration and Verification
Verification of the accuracy the above online measurement facilities will
carried out by means of laboratory analysis of probes at annual intevals (or
more frequently, as determined by INGL, acting as a Reasonable and
Prudent Operator). In the event of discrepency between the online facilities
and the laboratory analysis, the measurement equipment shall be
recalibrated. The maximum interval between calibrations shall be
determined in accordance with Statutory Requirements, or, if not applicable,
in accordance with the recommendation of the manufacturer of the
Appendix 5

provisions of this paragraph, the Parties (or either of them) shall
forthwith notify the Expert of the Expert's selection and shall
request the Expert to confirm to both Parties within seven (7)
days whether the Expert is willing and able to accept the
(e) If the Expert is unwilling or unable to accept such appointment
or shall not have confirmed the Expert's willingness and ability
to accept such appointment within such period of seven (7)
days, then (unless the Parties are able to agree upon the
appointment of another Expert), the matter shall be referred (by
either Party) to the Natural Gas Authority who shall be
requested to make an appointment or (as the case may be) a
further appointment and the process shall be repeated until the
Expert is found who accepts appointment.
(f) The Parties shall co-operate with each other to ensure that the
terms of the contract of appointment of the Expert are agreed
with the Expert as soon as possible. The Parties agree that, if
there shall be any dispute between them as to the amount of

which materially conflicts, or may materially conflict, with his function
under such appointment, provided that such Person shall, whether
before or after accepting such appointment, immediately disclose any
interest or duty of which he is or becomes aware and which conflicts,
or may conflict, with his function as the Expert and the Parties shall,
after such disclosure, have confirmed such Person's appointment or
continuing appointment.
1.4 If, within seven (7) days of becoming aware of a conflicting interest or
duty, either Party objects to an appointment or proposed appointment
of an Expert because it considers that there is a material risk of such
interest or duty prejudicing the decision of the Expert or proposed
Expert, the provisions of paragraph 1.5 shall apply.
1.5 In the circumstances described in paragraph 1.4 above, either Party
may apply to the Natural Gas Authority, who shall decide whether, if
such Person were to continue as Expert or were to be appointed as
Expert (as the case may be), such a material risk would exist. In so
deciding, the Natural Gas Authority shall consider any submissions
that either Party may wish to make. If the Natural Gas Authority shall
so decide, the Natural Gas Authority shall (if necessary) appoint a
replacement Expert in accordance with paragraph 1.1 above.
