- Abstract:
- Since 1997, EDF Research and Development Division has been carrying out liquid flow metering studies on the EVEREST experimental loop at EDF Lab Chatou (France). In the last twenty years, industrial flow meters designs have been continuously improved by manufacturers. In the same time, the need for industrial flow measuring instruments with a high accuracy has tremendously increased due to the required economic costeffectiveness in the energy sector. Flow meters metrological assessment tests consequently need to be upgraded in order to remain relevant. In 2016, EDF R&D has then initiated a complete revamping of the EVEREST test bench which was achieved at the beginning of 2019. This comprehensive retrofit leads to a significant calibration accuracy improvement. The EVEREST reference volume flow uncertainty is now better than 0.1% from 50 m³.h-1 up to 1200 m³.h-1. Moreover, in order to characterize the velocity profile impact on industrial meter metrological performance, two laser velocimetry measurement systems have been purchased. This effort leads also to the design of a mini-loop, called MONT-BLANC, whose purpose is to mimic EVEREST calibration features under a smaller size and a lower flow rate rangeability (from 13 m³.h-1 up to 150 m³.h-1). This test bench will allow not only to ease optical adjustments of laser-based velocity measurement techniques and their future implementations on EVEREST but also to provide an effective tool to investigate the influence of scale effect on flow meters and pipes flow physics.
