A recent project to assess a fiscal metering system used to measure oil loaded onto rail transport has highlighted how NEL, as a National Measurement Institute, applies its knowledge and expertise to ensure best practice in industrial measurement.
“The work involved an assessment of a turbine meter to investigate possible discrepancies in its operation,” says CFD Team Manager, Marc Laing. “The meter is used as part of the custody transfer chain in a refinery. We were able to pin-point the problem and suggest the best approach to fix the system.”
“As the holder of the UK’s National Standards for flow measurement, we are one of the foremost authorities on flow measurement technology in the world today,” Marc adds. “This places us firmly at the top of the audit chain and means that we can provide expert, impartial advice, as we did in this project.”
According to Marc, the assessment work involved a pre-audit of the metering system’s piping and instrumentation, its instrument datasheets and master meter proving data. Historical data was also reviewed and a new meter prove was witnessed on site.
“We employed our expertise in flow measurement, fluid mechanics, proving techniques and meter operation, says Marc. “Our comprehensive knowledge of the correct functioning of all major metering technology meant that we were able to give focused, practical advice.”
The importance of the project from an operational point of view comes from the fact that, in the transportation and distribution of oil and other fuels, the uncertainty of the measurement of each custody transfer step must be within strict limits. This makes it vitally important that the metering systems used in these circumstances are functioning correctly.
