Abstract
Electricite de France Research and Development Division (aka EDF R&D) has been investigated liquid flow meters metrological behavior for 20 years on EVEREST test bench. Experimental studies once focused on simple calibration tests on usual or innovative flow meters with high upstream straight length pipes have turned into sensors uncertainty characterizations campaigns under real industrial installation conditions. In order to enhance these studies, EDF R&D has come to the conclusion that, in many cases, accurate flow metering uncertainty calculations need comprehensive velocity profile understanding. This key feature can be achieved by mixing CFD results and experimental data. With regard to the latter point, upgrading the EVEREST test bench has become mandatory. Consequently, future EDF R&D flow metering test bench will aim at not only performing flow calibration tests but also at characterizing real liquid velocity fields for industrial pipe flow configurations. This upgrade has recently been accepted and is currently in progress. Renovation works and technological improvements will hopefully be achieved in 2018.
