European Metrology Research Programme (EMRP)

The science of measurement - metrology - is important for scientific research, industry and our everyday lives, as the demand for measurements with high accuracies and low uncertainties continues to increase. The European Metrology Research Programme enables European metrology institutes, industrial organisations and academia to collaborate on joint research projects within specified fields. These collaborative efforts will accelerate innovation in areas where shared resources and decision-making processes are desirable due to economic factors and the distribution of expertise across different countries and sectors. The EMRP is implemented by EURAMET, organised by 22 National Metrology Institutes (NMIs), supported by the European Union and has a value of 400 M € over an app. 7 year period. The preceding project iMERA-Plus (implementing Metrology in the European Research Area) had a value of 64.6 M €.

Flow Metrology for Liquefied Natural Gas (LNG)

About LNG

Liquefied Natural Gas is produced by cooling down natural gas below its dew point (-161 °C)

A unique solution for transporting natural gas to areas far from a pipeline structure

The volume occupied by LNG at atmospheric pressure is about 614 times smaller than its gaseous state – this reduces the space needed to freight an amount of energy

LNG is shipped in carriers from liquefaction plants to large tanks in buyer countries

These wessels can load from 145,000 to more than 200,000 m3

The energy volume of such a consignment corresponds to 1 – 1.4 TWh

One LNG cargo represents the annual power consumption of roughly 200,000 households in Denmark.

Energy = Volume x Density x Gross Calorific Value

Inaccuracies involved in the measurements of the parameters given in the above equation according to the G.I.I.G.N.L. (International group of Liquefied Natural Gas Importers) Handbook (2010):

Element calculated Total accuracy (%)

Volume ± 0.21

Density ± 0.23

Gross calorific value ± 0.30

Overall LNG energy transferred ± 0.43 (Annual power consumption in 86 Danish households)

The Handbook is not a standard but a document providing guidance to the industry by describing common practice. As of yet a thorough metrologically sound uncertainty budget has not been conducted.

The project’s overall objective

To contribute to a significant reduction of uncertainty in the determination of transferred energy in LNG custody transfer processes

(1% uncertainty = 440 M€/year in 2010 and 900 M€/year in 2015)

Static versus dynamic volume measurements

Typically

– Level gauging + gauge table (static)

– Correction tables

– Uncertainty: 0.2 – 0.5 % ?

Alternative

– Volume rate meters (dynamic)

– Uncertainty: 0.2 – 0.3 % ?

– No direct traceable link to SI units

Calibration facility required!

Novel mathematical and statistical approaches to uncertainty evaluation EMRP Project – Introduction and overview

November 2012

Lars Poder, FORCE Technology

Better measurement uncertainty analysis

The evaluation of uncertainty in measurement is fundamental to measurement science. Without

it results cannot be compared, and unreliable uncertainty evaluations can have huge negative

economic, health and environmental impacts.

The Guide to Uncertainty in Measurement (GUM) contains existing approaches to uncertainty

evaluation, but these may not be appropriate for modern applications such as biochemical and

nanoscale measurements.

This project will develop new approaches to measurement uncertainty evaluation and enable

their consistent application. It will focus on three areas where new uncertainty analysis methods

are needed:

1) inverse and regression problems,

2) computationally expensive model functions,

3) conformity assessment and reliable decision making.

These new analysis methods will improve product testing, safety regulations, medical diagnosis

and drug testing, and will provide input for future revisions of the GUM.
