The test points are listed in Table 4. The three cardinal points were the flow rates at Reynolds numbers of 70 000, 100 000 and 300 000. The participants calibrated the transfer standard at Re of 100 000 at least. The required flow rate was between 60 m3/h and 300 m3/h at the cardinal points. The liquid temperature through the transfer standard at calibration condition was approximately between 20 ºC and 30 ºC. The viscosity of liquid at calibration condition was between 1.5 mm2/s and 7.0 mm2/s. The back pressure downstream of the flow meter was more than 0.1 MPa. The pressure at the flow meter was between 0.1 MPa and 0.6 MPa.

In NMIA a small volume prover is used as a reference standard. Therefore, the number of passes followed normal procedure at NMIA. The number of passes was reported in the results data sheet.

5.2. Temperature and viscosity effect The transfer standard was calibrated at different temperature in kerosene (KE) and

light oil (LO) at NMIJ before the comparison in order to investigate the effect due to temperature and viscosity on the K factors. The calibrated flow rates were between 60 m3/h and 300 m3/h. The calibrated temperatures were 15 ºC, 20 ºC, 25 ºC, 30 ºC and 35 ºC. The relative K factor of the transfer standard at different temperature is shown in Fig. 7. The standard deviation due to temperature and viscosity at the cardinal points is shown in Table 6. The standard uncertainty due to the difference of temperature and viscosity between each pair of the participants is estimated to be 0.005 8 % at maximum.

than 50 000, was described by the second function equation of Equation(4).

The relative standard uncertainty due to the differences of Re at the cardinal points between each pair of the participants is estimated to be the largest value of 0.002 8 % at Re of 300 000.

5.4. Pressure effect The relative K factor of the transfer standard at different pressure is shown in Fig. 8.

The calibrated liquid was light oil and the liquid temperature was 35 ºC. The pressure effect on the relative K factors is less than 0.003 4 %/MPa, and the difference of liquid pressure between each pair of the participants is estimated to be less than ± 0.025 MPa. Therefore, the standard uncertainty due to the difference of the pressure between each pair of the participants is estimated to be 0.000 9 %.

5.5. Effect due to upstream condition The strainer was set upstream the transfer standard at calibration in the comparison

and the PD meter was used as the transfer standard, indicating that the transfer package is hardly affected by the upstream condition in the test rig of the participants. The effect due to the upstream condition was estimated by the difference of the K factors with the strainer from those without the strainer. The relative difference of the K factors with the strainer from those without the strainer is shown in Fig. 9. A PD meter which is the same type of the transfer standard was calibrated with the transfer standard. The calibrated liquid was light oil and the temperature was 20 ºC. The relative standard uncertainty due to the difference of the upstream condition between each pair of the participants STRu is estimated to be 0.003 1 % by Equation (7).

6.2. Calculation of the reference value and its uncertainty The analysis of the results was carried out according to the methods specified by

Cox[4]. At Reynolds number of 70 000, 100 000 and 300 000, the comparison reference values (KCRV), which provide linkage to CCM.FF-K2[1], is obtained based on the method used for EUROMET Project 345[7]. CMS and NMIJ participated in both comparisons, CCM.FF-K2 and APMP.M.FF-K2.a. Assumed that the calibration results in the both linking laboratories are maintained between CCM.FF-K2 and APMP.M.FF-K2.a, the calibration results obtained at the linking laboratory i in APMP.M.FF-K2.a

iK is corrected by the difference of the calibration results of the linking laboratory from the KCRV of CCM.FF-K2 CCM,id . The relative value corrected by the KCRV of CCM.FF-K2 for APMP.M.FF-K2.a ,C iK is given by Equation (8).

8. Summary and conclusionsThree laboratories: CMS, NMIA and NMIJ, participated in the key

comparison for hydrocarbon flow measurement. A screw type positive displacement flow meter was selected as a transfer standard.

The performance of the transfer standard and its stability was evaluated from the measurements of the pilot institute, NMIJ. The transfer standard showed high performance and good stability since the uncertainty due to the transfer standard was less than quoted uncertainties in the participants.

CMS and NMIJ have En values which show consistency with both the relevant KCRV for APMP.M.FF-K2.a and each pair of participants. However some En values for NMIA were from 1 to 1.2, indicating “alert”.

APPENDIX B Methods of measurement

B.1 CMS

The transfer standard (TS) is calibrated by the low viscosity oil flow calibration system. A solvent oil of Exxon D110 is used as the working fluid. Meanwhile, the standing-start-and-finish mode with static weighing method is used to calibrate flowmeters.

The low viscosity oil flow facility is a circulating system. The working fluid is pumped from a reservoir and flows through the meter under test, a flowrate control valve, an on-off valve, and a constant level device. Then the liquid falls freely into the weightank. After being weighed, the liquid in the weightank flows back to the main reservoir by opening a valve on the outlet pipe of the weightank. The process flow diagram is shown as Figure B-1-1. A photograph of the calibration setup is shown in Figure B-1-2.

1. Test rig and Calibration method1) Test rig and Calibration methodA schematic of the primary standard for hydrocarbon flow is shown in Fig. B-3-1. Light oil and kerosene are used as working liquids; each oil has a separate test line. As they share a heat exchanger, however, the two lines cannot be operated at the same time. The flow rate range of the facility capacity is from 3 to 300 m3/h. This primary standard is based on static and gravimetric methods with a flying start and finish, i.e., the total mass of fluid passing through the flowmeter via the diverter in a given time is measured. It consists of a 10 t weighing scale, a 1 t weighing scale, a density meter and the diverter system, which has double diverting wings.

2. Expression of uncertainty.The uncertainty budget as a base uncertainty is shown in Table B-3-2. The combined relative standard uncertainty for volumetric flow at this calibration facility is simplified to be 0.015 %. The relative combined standard uncertainty of the K-factor is estimated in combination with the uncertainty of the experimental standard deviation of the mean due to the random effect, which normally is negligible. Accordingly, the relative expanded uncertainty of the K-factor for volumetric flow is estimated to be 0.030 % (coverage factor k = 2).

1) Uncertainty of DensityThe density of the liquid was measured using the oscillating U-tube density meter,

DMA5000 or DMA5000M, which were manufactured by Anton Paar. This is based on the principle of a U-tube which has a resonant frequency that is inversely proportional to the square root of its mass. The density meter was calibrated using the standard density liquids of water, whose expanded uncertainty (k = 2) is 0.030 kg/m3. The standard uncertainty of the density measurement was estimated to be 0.052 kg/m3, because the uncertainty due to the viscosity effect was estimated to be 0.050 kg/m3.

2) Uncertainty of ViscosityViscosity of liquid was measured using the Viscometer, AMVn or SVM3000, which

was manufactured by Anton Paar. The Viscometers were calibrated using standard viscosity liquids, whose expanded

uncertainty (k = 2) is less than 0.1 %. However the measurement uncertainty of viscosity is dominant on the linearity and the reproducibility of the device. The Expanded uncertainty of viscosity was roughly estimated to be 3 %. The uncertainty of the density is negligible against that of the viscosity. Therefore, the uncertainty of Reynolds Number is estimated to be 3 %.

1. PurposeThis key comparison, APMP.M.FF-K2 is performed by APMP Technical Committee

for Fluid Flow (APMP/TCFF) for the purpose of determining the degree of equivalence of the National Standards for hydrocarbon flow measurement among participating National Metrology Institutes (NMIs). The participating NMIs will test a transfer standard and compare their calibration results. National Metrology Institute of Japan, National Institute of Advanced Industrial Science and Technology (NMIJ/AIST) has been assigned as the pilot laboratory.

This protocol has been prepared to perform the key comparison in accordance with the Guidelines for CIPM Key Comparisons (the “Guidelines”) [CIPM 1999] and the Guidelines on conducting comparisons [APMP-G2].

A positive displacement flow meter (KRAL meter) is to be used as the transfer standard. It will be tested by each participating laboratory at Reynolds number of 100,000 and at Reynolds numbers selected from 70,000, and 300,000.

After the measurement is completed, the degree of equivalence (DoE) between the participating NMIs will be obtained at every cardinal point, at Reynolds number of 70,000, 100,000 and 300,000. The key comparison reference value (KCRV) and the DoE between the KCRV and each of the participating NMIs will be also obtained.

2. Administrative information2.1. Package of the Transfer Standard

The transfer standard (TS) will be shipped using an ATA Carnet1 . The TS shall be shipped in two transportation box. Box A measure 630 mm (depth) × 990 mm (width) × 755 mm (height) and weighs 280 kg including the TS. Box B measure 380 mm (depth) × 380 mm (width) × 410 mm (height) and weighs 35 kg including the pipe.

2.2. Participating NMIs, test schedule and transportation A list of the participating labs, their shipping addresses and contact information is

provided in Table 1. Each lab has been allotted three weeks for testing and two weeks are reserved for shipping. Each participating NMI must ship the TS by fastest and safest way and the TS should be insured during shipment for at least 30,000USD. Each participating NMI shall pay the shipping and the insurance cost derived from delivery to the next participating NMI.

2.3. Keeping test schedule After the comparison starts, the participating NMIs must to send the TS to the next

participating NMI at on the schedule to prevent disruptions in the KC schedule even if their measurements are not completed. Participating NMIs, who cannot complete their measurements, will be assigned a new test date by the pilot after the entire original test schedule is accomplished.

1 For transportation between Taiwan and Japan, a SCC Carnet will be used.


54

2.4. Loss or damage of TS The transfer standard is robust and it is contained in a strong shipping container,

however if the TS is damaged or a participating NMI finds it to be malfunctioning, they should consult the pilot lab for advice. The pilot will have a backup TS if a replacement is needed and spare parts that might be used to repair the entire TS. In the event of total loss, results from the backup TS would be normalized with data from calibrations at the pilot lab.

2.5. Special mailing address for the pilot lab E-mail messages being sent to NMIJ regarding this key comparison should be

addressed to "[email protected]". Then the message will be distributed to the NMIJ personnel in charge.

4. Preparation at a participating labPrior to receiving the transfer standard, each participating NMI should prepare pipes

and signal cables for its calibration facility to accommodate the flowmeter. The schematic of the package is shown in Appendix 1.

Each laboratory should be notified of the actual arrival date of the package by the previous laboratory. If no notification is received when expected, please check with the previous laboratory. Please inform the Pilot laboratory immediately if a problem has arisen.

If during the testing, a problem arises, please inform the Pilot for advice. Inform the next laboratory if a delay in completion is expected.

5. Unpacking the Transfer Standard5.1. Receiving check list

When the transfer standard arrives at a participating lab, Form 1 "Receiving Checklist" (see, Appendix 2) must be filled out and emailed to the pilot lab ([email protected]). The procedure of the receiving check is described in the following sections.

5.2. External examination of Transportation box Make a visual check of the external of the transportation boxes.

5.3. Checking the contents Take out all the items from the boxes and inspect them visually one by one. Take

some pictures of the inlet and outlet of the flow meter and then the pictures should be emailed to the pilot lab ([email protected]). Report any damage or missing parts to the Pilot and the previous laboratory.

5.4. Reporting the receiving check result After the check is completed, the Form 1 "Receiving check list" should be e-mailed

to the pilot lab ([email protected]). If problems are found, the participant should describe them in detail on a separate sheet (preferably in a MS-Word file), and send it along with the Form 1.

6. Measurement Procedure6.1. Preliminaries

1) The required test liquid is clean hydrocarbons such as kerosene and light fuel oiland so on.

2) Prior to the start of testing, measure viscosity and density of the oil across theexpected temperature range. Prepare density and viscosity equation coefficients.

3) Density equation should be in the form of a linear fit to data collected across atemperature range at least 20 to 30 ºC. Density should be quoted as kg/m3.

4) Viscosity should be measured over the same temperature range. Viscosity shouldbe quoted as mPa·s.

5) Remember the equations should relate to the oil at the time of the test but arerequired before testing is started to allow a dynamic calculation of Reynoldsnumber.

6) The fluid density and viscosity data should be provided as an annex to the reportand include an estimated uncertainty. The data should also be provided in thereporting spreadsheet.

6.2. Installation and filling 1) The package should initially be assembled according to the configuration(See

Appendix 1).2) The installation should be carried out according to normal best practice adopted

for a normal client flow meter calibration. No specification has been given as tothe nature, length or type of pipework up or downstream of the package.

3) Set lab's pressure gauges at the two pressure taps of the upstream pipe ifnecessary. Pressure drop at the upstream pipe is approximately 20 kPa at theflow rate of 300 m3/h and the kinematic viscosity of 7.0 cSt.

4) Connect up the meter signal instrumentation. The wiring and connectionspecifications will be provided in Appendix 1.

5) When filling the package and establishing flow, ensure upstream and downstreamvalves are closed to prevent air from over-speeding the meter when the pumpsare started.

6) Gently allow the package to fill with oil and bleed out all air.

6.3. Choice of test points 1) Carry out the test procedure as given in Table 13. The three cardinal points are

the flow rates at Reynolds numbers of 70,000, 100,000 and 300,000. Theparticipants should calibrate the transfer standard at Re of 100,000 at least. Flowrate should be between 60 and 300 m3/h at the cardinal points.

2) The liquid temperature through the transfer standard at calibration conditionshould be approximately between 20 ºC and 30 ºC. The viscosity of liquid at


59

calibration condition should be between 1.5 cSt (mm2/s) and 7.0 cSt. Back pressure downstream of the flow meter should be more than 0.1 MPa. Pressure at the flow meter should be between 0.1 MPa and 0.6 MPa.

3) The number of reputation measurements at the cardinal points should be thesame as that at normal calibration. If the number of reputation measurements isnot specified, the recommended number is 6 as shown in Table 13.

4) If a small volume prover is used as a reference standard, the number of passesshould follow normal procedure at each lab. The number of passes should bereported in the results data sheet.

5) From the fluid properties and the flow rate, the Reynolds number at each flowrate will be calculated. Reynolds number is expressed as

4Re QD

ρπµ

= (29)

Q : Volumetric flow rate (m3/s) ρ : Density (kg/m3) D : package inlet diameter as given (=0.15 m) µ : Dynamic viscosity (Pa·s)

6) The cardinal flow point has been specified by Reynolds number and not by flowrate. Reynolds number is based on the inlet diameter of the flow meter upstreampipe(=0.15 m). The volumetric flow rate through the flow meter is used to set theReynolds number. Difference of Reynolds number from the cardinal points shouldbe less than ±5 %.

6.4. Limited flow range Where the laboratory can not reach the maximum flow rate, the maximum

achievable flow rate may be reported on the summary sheet in place of the next highest specified point. Cavitation must be avoided at all times.

6.5. Timescales Tests should be carried out within consecutive working days as possible. Durations

of more than one day should be reported in the final report. The laboratory should not have the package longer than three weeks.

6.6. Draining the package Drain the package carefully ensuring the meters do not exceed the maximum flow

rate during draining.

6.7. Uninstallation and dispatch 1) Safely disconnect and pack instrument cables and connectors.


60

2) Remove the package from the test line. Drain all residual oil from the meters andfilter. Clean or re-install the filter.

3) Deal with anti-rust treatment (ex. anti-rust spray) to the wetted part of the PDmeter.

4) Take pictures of the inlet and outlet of the flow meter in order to confirm conditionof the flow meter and the pictures should be emailed to the Pilot before packing.

5) Re-assemble for dispatch.

7. Shipping the Transfer Standard1) Please pack the transfer standard in the transportation box properly and fill the

Form 3 "Shipping Checklist" (see Appendix 2). The information needed forpacking is provided in Appendix 1.

2) Each participating lab is responsible to select an appropriate transportationcompany and to ship the transfer standards as precision instruments. Alltransportation cost are to be afforded by the participating laboratory. The TSshould be insured for at least 30,000USD.

3) After shipment, the completed Form 3 "Shipping Checklist" should be e-mailed to"[email protected]" and to the next participating lab.

8. Reporting the measurement result8.1. Test data to be reported

1) Fluid property data as previously specified. This is to be in an annex to the reportand should indicate the density and viscosity measurements across the


61

temperature range used to establish the fluid property equations. A brief description of the measurement method, uncertainty and fluid property equations should be given. Data should be provided on the report spreadsheet.

2) A description of the calibration test rig, including a sketch drawing indicating thegeneral principle of the test rig and the installation of the meter including pipesizes and lengths immediately upstream and downstream of the package.

3) A brief description of the test method used4) Required data in Form2 (See Appendix 2): The following data may be considered

as a minimum requirement for each test point:-.Point number, Date, flow rate through the flow meter, mean temperature at the flow meter, mean pressure at the flow meter, ambient temperature, kinematic viscosity and density at the flow meter under the calibration, meter pulses collected, measured time, and fluid volume passed through the package at test conditions.

5) The participants should calculate actual K factors at calibration condition. This isnot referenced to standard conditions.

6) The data transcribed to the summary sheets in Form 2 (See Appendix 2) shouldbe included. The following results at the cardinal points should be calculated andreported.

Type of liquid, kinematic viscosity (X10-6 m2/s = cSt), Density (kg/m3), flow rate (m3/h), liquid temperature at the flow meter (ºC), pressure at the flow meter (MPa), K-factor (P/L), base uncertainty (%), DUT uncertainty (%) and expanded uncertainty of K factor (%).

7) If the participants carry out extra calibration, all results should be reported.

8.2. Expression of uncertainty 1) The standard uncertainty of K factor is combined with the base uncertainty of the

reference standard based on the GUM and the standard uncertainty due to therepeatability of calibration results. The expanded uncertainties of K factors shouldbe quoted in percentage term with coverage factor k=2. Each quoted value shouldbe rounded up to two decimal places.

2) It would be helpful if a summary of the main uncertainty components for themeasurement could be given in no more than half a page of text or table(s)

3) To allow a calculation of the uncertainty in Reynolds number, an uncertaintyestimate of the measured viscosity and density should be provided.

4) To report the calibration result, fill the Form 2 (see Appendix 2) and email to [email protected].

9. Data Analysis by the Pilot Lab1) The K-factor is used to calculate a corrected K factor based on 20 ºC expressed


62

as:

( ){ }20 1 20f fK K Tα= + − (30)

α : Coefficient of linear expansion of material. (Steel for flow meter, =1.1X10-

5 (K-1)) T : Temperature at calibration condition (ºC)

2) At Reynolds number of 70,000, 100,000 and 300,000, the comparison referencevalues (KCRV), which provide linkage to CCM.FF-K2, will be obtained based onthe method used for EUROMET Project 345 [Delahaye and Witt, 2002]. Then thedegree of equivalence (DoE) between the KCRV and each of the participant, andDoE between each pair of the participants will be calculated. NMIJ and CMS willserve as a linking laboratories.

3) At Reynolds number of 70,000, 100,000 and 300,000, the DoE among theparticipants will be calculated.

4) Draft A and Draft B will be distributed to the participants in accordance with the Guidelines.
