Training course: Fiscal metering of natural gas, wet gas metering and impact of new gases

Best practices in design & operation of fiscal metering and gas production stations
Energy storage webinar series

Are you sure that ambient conditions at natural gas fiscal metering stations are not influencing your volume, temperature and pressure measurement? And do you know the causes of your unaccounted for gas? Find out how to design and operate your fiscal metering stations in order to minimise systematic errors. Learn how to judge whether the company that measures your natural gas is generating accurate data and push your gas balance to the equilibrium.

Since the Netherlands adopted natural gas in the 1960s, DNV has been involved in the design and operation of natural gas metering stations. Optimising combustion processes in terms of efficiency, emissions and safeguarding equipment was another subject since the 60’s. In 2013, DNV introduced a multiphase flow test loop, which is used to assess wet gas and multiphase flow meters.

Your benefits

After attending this course, you will have gained both practical and theoretical knowledge of designing and operating fiscal metering systems for natural gas. You will understand the principles of designing and operating your fiscal metering stations in order to minimise systematic errors and how this will help you push your gas balance to equilibrium. You will be fully aware of the fact that designing an accurate measurement system not only requires sound knowledge of metering techniques, but also practical experience of do’s and don’ts. Errors in measurement data have direct financial implications, making this knowledge very valuable to you and your organisation.
