functions. Pneumatic signal transmission will only be used for local control loops and
final element control.
Local pneumatic control loops should be avoided, unless specifically required for a
particular application e.g. vendor packages.
Control valves will be pneumatically operated unless specified otherwise.
Where pneumatic as well as electric signal transmission is applied (e.g. control valve),
smart E/P positioner shall be provided.
2.5.2 Electric Signal Transmission
The analogue signal transmission range should normally be 4 to 20 mA DC.
The voltage level for signal transmission should normally be 24 VDC.
The signal transmission should normally be a 2 wire system (powered by receiving
devices).
Instrumentation for special purposes, such as for machine monitoring, tank gauging
systems, fire and gas detectors, etc. may have other signal ranges, signal
transmission voltage levels and multiple wire systems.
Signals from thermocouples and resistance thermometers fitted to a package or in a
control loop shall be converted to 4 to 20 mA DC, in the field at the measuring device
or local to it, other signals will be run directly.
Electric signal transmitter shall be supplied smart with hart protocol type as “Duon or
equivalent”.
2.5.3 Pneumatic Signal Transmission
The operating range for pneumatic signal transmission shall be 0.02 to 0.1 MPa.

(cover) in place and equal to or less than +/-0.5 % of the output span with the
instrument enclosure (cover) removed.
2.12 TRANSMITTER LOCAL INDICATORS
Smart type transmitters using hart protocol for signal transmission with integral digital
indicators shall be used. If a transmitter output indication is required to be read from a
control valve, care should be taken in using the integrally-mounted indicators to ensure
that they can be read from the relevant location, if it is not possible separate digital
local indicators should be used.
All local indicators shall have a scale calibration as follows:-
Flow* Actual range (t/h or kg/h)
Level Actual range (%, m, mm)
Pressure Actual range
Temperature Actual range
Other variables Actual range
2.13 DIAPHRAGM SEALS
Diaphragm seals shall normally be integral with the instrument. The application of
diaphragm seals with capillary extensions shall be kept to an absolute minimum.
When a diaphragm seal is required, the largest practical size should be applied.

4.0 FLOW INSTRUMENTS
4.1 GENERAL
Differential Pressure (DP) type flowmeters or vortex flowmeters will form the basis of
most of the flow measuring activities in the KOGAS Samcheok LNG Terminal. However,
other types of meter may be considered for certain duties.
The basis for the design of differential pressure-type flowmeters is the publication ISO
5167-1~4, 'Measurement of fluid flow by means of orifice plates, nozzles and Venturi
tubes inserted in circular cross-section conduits running full'.
Where a flow measurement is to be used in a shutdown as well as an operating
function a single primary element with separate transmitters should be used. i.e. For
an orifice plate, two DP transmitters each with its own set of process connections; for
vortex meters, the same bluff body with two sensors/amplifiers/power supplies.
4.2 FLOW RATE MEASUREMENT
Differential pressure type flow instruments or vortex flowmeters up to 6", should
generally be applied for flow rate measurement. The selection of which type of
instrument to use should be on a cost basis of the complete installation.
Special considerations on particular services may require the use of alternative
methods such as:-
- variable-area flowmeters
- electromagnetic flowmeters
- thermal flowmeters
NOTE: Installation requirements similar to those for differential pressure-type flow
instruments also apply for electromagnetic or vortex flow meters, with regard to
straight length requirements, upstream and downstream of the instrument. Moreover
the supplier’s maximum allowable distance between the flow meter head and the
related electronic converter shall be observed.
The volume corrector shall be supplied with flow meter or flow transmitter in the F/G
line.
4.3 VOLUME MEASUREMENT
Turbine or ultrasonic meters shall be specified when necessary for custody transfer.
They may also be considered for applications where a higher accuracy or a higher
rangeability is required than is obtainable with the flow rate instruments listed.
4.4 SIZING OF DIFFERENTIAL PRESSURE TYPE FLOW METERS
Flow element sizing calculations will be based on ISO 5167-1.
30-I-O00-SP-205
- 12-
The primary elements should be sized for use with differential pressure transmitters
having one of the following preferred ranges: 0-5, 0-12.5, 0-25 or 0-50 all in kPa.
Based on a linearized scale of 0-10, the flowmeter shall be ranged for a reading at:
1) Maximum flow between 8.0 and 9.5 of the scale.
2) Normal flow between 5.0 and 6.0 of the scale.
3) Minimum flow not below 2.0 of the scale for flowmeters used in accounting,
material balancing and alarm or tripping applications.
4) Minimum flow not below 1.0 of the scale for all other applications.
The d/D (Beta) ratio shall be between 0.3 and 0.7. The "top of chart" flow rate shall
generally be chosen as a rounded value conveniently greater than the maximum flow.
The preferred flowmeter range is 0-25 kPa. Ranges above 50 kPa shall not normally
be used.
Where the above requirements are conflicting, two or a maximum of three flowmeters,
having different but overlapping ranges shall be selected.
Square root flow signals shall be linearized in the transmitter not at the systems,
unless the square root signal is required in the system calculations.
4.5 ORIFICE PLATES
The "measurement uncertainty" for an uncalibrated orifice plate flow measurement
loop is +/- 1 to 5% flow, utilising a +/- 0.1% analogue DP transmitter (smart type) and
the straight length requirements specified in ISO 5167-1, within a turndown not
exceeding 4:1.
Orifice plates shall conform with the dimensions and tolerances specified in attachment 1.
Sharp edged, concentric orifice plates should be used. The minimum orifice bore shall
not be less than 12.5 mm diameter.
The minimum pipe size for orifice plates shall be 2". Where the pipe size is less than 2",
it should be increased to 2" for the meter run.
Flange taps shall normally be used. Orifice taps are socket welded or threaded in
accordance with the data sheet. Threaded taps shall be 1/2" NPT. Tap locations for
horizontal lines shall be on the horizontal centre line.
Orifice flanges should be the weld neck type. The Minimum Orifice Flange Rating shall
generally be ANSI Class 300. The use of other rating flanges or facings, other than
raised face, shall be used as required by the piping specifications. The plate surface
finish in the gasket joint area shall be appropriate for the gasket materials, which will
be supplied by the orifice plate manufacturer.
30-I-O00-SP-205
- 13 -
Orifice plates shall include a vent or drain hole when appropriate for the service and
application. e.g. A horizontal line installed orifice in "wet" vapour or saturated steam
service shall have a drain hole. A horizontal line installed orifice in a liquid service
where the liquid may include entrained gas or be close to being dual phase shall have
a vent hole.
Orifice plates in vertical lines shall not have vent or drain holes.
The plate material shall be 316 stainless steel unless other materials are more suitable
or are specified for the intended application.
4.6 VENTURI TUBES
Venturi Tubes or low loss flow tubes shall be considered:
- where high pressure recovery is required,
- where only low inlet pressure is available,
- where extreme high beta ratios would be required with an orifice plate,
- where resistance to abrasion is required ,
- where suspended solids must be passed,
- where meter run space is limited.
4.7 FLOW METER INSTALLATION
Because the pressure measurements are small, DP transmitters on flow service shall
be installed with great care, with the minimum lengths of impulse piping, to prevent
errors affecting the accuracy of the installation.
The possibility of changing and/or different levels (static heads) of liquid occurring in
the high and low pressure legs of the connecting impulse lines shall be prevented.
These problems can particularly occur in cryogenic service, where a build up of ice can
affect the heat transfer rate from impulse lines, so heat tracing on the impulse lines
shall be installed to ensure continuous vaporisation of liquid and hence a consistent
and reliable liquid/vapour interface level (static head) in both impulse connections.
Generally liquid service transmitters shall be mounted below the line with diaphragm
seals and vapour/gas/LNG service transmitter above the line. Where this is not
possible using an alternative flow measurement instrument should be considered,
although there are various solutions that can be considered to over come these
problems, e.g. seal pots.
The installation in pipelines of orifice plates and venturi tubes, shall be in accordance
to ISO 5167-1, with a +/ - 0.5% additional uncertainty value, at a Beta Ratio of 0.7.
Exceptions to these installation recommendations may be necessary or acceptable for:
- High accuracy applications required for accounting or mass balance measurements
where increased lengths may be required.
30-I-O00-SP-205
- 14-
- Costly and awkward piping arrangements created to provide the specified straight
lengths, where by taking account of the Beta Ratio of the actual element if <0.7 a
shorter length, which will simplify the arrangement, can be considered
Straightening vanes shall not be used as a means of decreasing the upstream straight
pipe requirements until every effort has been made to avoid their use, and then only
when the source of upstream flow disturbance is other than that caused by a single
elbow, tee, or reducer. Straightening vanes shall not be used in lines smaller than 3".
Pre-fabricated Meter Tubes shall be supplied where required, which will be identified
on the P&ID's and where a 2" meter run is fitted in a line <2". The meter run shall be
manufactured by a specialty fabricator and the upstream and downstream pipe
between the orifice plate and the nearest fittings shall conform to the tolerances and
practices as recommended by ASME "Fluid Meters".
Flow elements shall be installed upstream of a controlling globe, or throttling gate valve
unless permitted otherwise.
4.8 VORTEX FLOW METERS
Although vortex meters are a higher cost device than an orifice plate the overall
installation costs can be less. Also the rangeability is more than the 3 : 1 of an orifice
plate. Therefore each required installation should be reviewed to determine whether a
vortex meter should be used or not.
Further points for consideration are:
- the maximum allowable operating temperature
- the maximum allowable line size (6" typical)
- the minimum allowable pipe Reynold number (20,000 typical)
For use on cryogenic service the meters should have a proven record.
In special cases, a vortex meter may also be considered for line sizes >6".

with stainless steel internals, unless the application requires other materials.
The method for sensing the vortices shall be suitable for the particular application.

applications, such as measurement of purge, cooling or sealing fluids, or in sample
loops for on-line process stream analysers.
The meters shall have a metal metering tube, with a pressure rating which is
compatible with the maximum process conditions.
4.11 ELECTROMAGNETIC FLOW METERS
Electromagnetic flowmeters may be considered where no restrictions in the flow
stream are allowed, or a rangeability of more than 3 : 1 is required. The fluid shall have
a conductivity of at least 200 S/m at a temperature below the specified limit. For
measurement of fluid velocities below 1 m/s the instrument shall be of the DC-field
type.
4.12 ULTRASONIC FLOWMETER
Ultrasonic flow meter shall be used wherever the line sizes are very big and very
accurate metering may not be required such as the main flare header. They may be
used also in cases where other types of flow measurements are not feasible because
of service conditions or economic reasons.

strainer shall have a pressure drop of not more than 0.02 MPa, and in a dirty condition
the strainer internals shall be capable of withstanding a pressure drop of at least 0.3
MPa.
NOTE: The latter requirement is more stringent than that specified by most suppliers,
but is considered necessary to prevent the collapse of a dirty strainer.
A differential pressure indicator shall be installed across the strainer and a
differential-pressure alarm shall be provided:
- on all applications for custody transfer
- where frequent clogging of the strainer is expected.

considered for local indication.
30-I-O00-SP-205
- 17-
Level gauges or external level displacers shall not be used on cryogenic
vessels/drums (temperatures less than -60 oC).
The preferred type of level measurement for cryogenic applications is differential
pressure, with the transmitter mounted above the top tapping point on an access
platform, with a self purged process hook-up. (NOTE: all cryogenic vessels, where DP
transmitters are to be installed, would require platforms on top of the vessel.)
For special applications, other principles of measurement may be considered, such as
ultrasonic instruments or instruments based on capacity, conductivity, radioactivity,
radar/laser or bubbler type.
Standpipes for level instrumentation should be used, where appropriate, to reduce the
number of vessel connections for closed and pressure vessels containing flammable
or toxic fluids. The exception to this is for safety instruments, which shall be directly
connected.
Special provisions such as purging or heating should be considered to ensure proper
operation of level instruments for highly viscous liquids, or for liquids containing water
or solids, especially if the latter tend to form sediments.

account when specifying displacer instruments or calculating the range for
differential-pressure instruments.
