The Measurement Focus Group is supported by the UK Government's National Measurement System (NMS). The group focuses on flow measurement and flow-related issues in industry. Club members are invited to attend technical club meetings.
Delegates are primarily from the UK, but we often have presenters from USA, Norway and other parts of Europe. It's typically operators, consultants, manufacturers, service companies and also delegates from the UK Oil & Gas Regulator.

Agenda
- 11:30 Determining flare gas composition without a sampler Phil Stockton (Accord)
- Flare gas composition is required for environmental reporting to calculate emission factors (Te CO2/Sm3)
- Flare header sampling can be difficult resulting in unreliable sample compositions - the reliability of sample compositions can be cross-checked against ultrasonic flare meter speed of sound measurement
- Accord's CHARM process simulation package allows calculation of flare compositions based on live plant data, which is cross checked for accuracy against the USM speed of sound measurement
- This on-line tool reduces sampling frequency and costs
- 11:55 Lunch and networking
- 12:40 Density determination of LNG for accurate custody transfer Shima Ghanaatian (TÜV SÜD National Engineering Laboratory)
- The role of LNG density and compositional analysis in custody transfer and energy determination
- Measurement challenges arising from cryogenic conditions and compositional variability
- Current approaches to LNG density prediction, from empirical methods to modern equations of state
- Current progress in the CryoMet project towards improved density determination of LNG mixtures
- 13:05 Utilising diffraction to exploit chordal paths for swirl measurements in clamp-on USM array flowmeters Ben McHugh (Warwick University)
- Clamp-on ultrasonic flowmeters are widely used for non-invasive flow measurement, but traditional transit-time methods sometimes struggle with swirl-induced errors
- Ultrasonic diffraction enables non-diametrical paths from a transducer mounted normal to the pipe wall
- Combining multiple chordal paths enables measurement and cancellation of swirl effects.
- Initial tests show accurate swirl measurement and cancellation under zero axial flow.
- 13:30 Coffee and networking
- 13:45 4-tube “2-in-1” Coriolis design with two independent measuring tube pairs Jonathan Humphrey (Endress+Hauser)
- The effect of independent measuring tube pairs on measurement uncertainty
- Enhanced Zero Point stability validated under varying temperature, pressure and viscosity conditions
- The influence of a 4-tube design upon Reynolds number correction and pressure loss
- How independent measurements tackle transient disturbances and offer enhanced process insights
- 14:10 Chairperson’s closing remarks
- 14:15 Coffee and networking
- 14:15 Tour of Endress+Hauser Centre
- 16:00 Close
