Limiting Gas Measurement Uncertainty in the Field

Date: April 4, 2017
Time: 10:00 AM CST

How much are unknown issues costing your gas measurement operation?

Dirt buildup, liquids and other contamination within the pipe are taking a greater toll on measurement accuracy than you may realize. Even a minor flow disturbance can have a major impact on lost and unaccounted for (LAUF) product. A new risk-based assessment by DNV GL goes a step beyond traditional metrology testing to determine if the metering technology is robust enough to operate under actual operating conditions. Join us to discover how DNV GL is now qualifying ultrasonic meters with greater specificity than ever before.

What will you learn?
  • How daily operating conditions impact meter health and measurement accuracy
  • How to increase measurement reliability and reduce long term measurement uncertainty
  • How to better manage capital investments
  • How to improve compliance and streamline maintenance practices to reduce long term operating costs

Henk Riezebos, PhD

Principal Consultant, Metering and Flow Acoustics
DNV GL

Henk Riezebos is an internationally recognized expert in gas flow metering and acoustics with a strong background in the physical modelling of natural gas network phenomena and acoustic phenomena in natural gas systems (pulsations and vibrations). Since 2003, Henk has been a senior researcher at Gasunie Research involved in many projects where fundamental and/or experimental knowledge on performance of flow metering equipment is at stake. He has been appointed as a flow expert by the court of Rotterdam to solve a flow metering dispute between manufacturer and client, and has worked as an international project manager to investigate the do’s and don’ts of metering technologies in natural gas custody transfer systems. Henk has advised companies across the globe on metering policy, acoustics, and metering and calibration issues. His latest work involves initiating the DNV GL metering classification and benchmarking schemes based on ISO10012 to promote best industry practice in fiscal metering.
