Qualifying a Coriolis Condensate Export Metering Station for Fiscal Use for Ormen Lange Using 12' Coriolis Meters

摘要

Hydro has qualified a novel liquid export metering station design based on large Coriolis mass flow meters and Coriolis master meter proving for fiscal use in Norway, with very good results. The extensive testing activity resulted in significant improvements to the internal measurement and compensation algorithms in the Rheonik Coriolis mass flow meters and some changes in the metering station design and in the flow computers. The larger size Rheonik Coriolis mass flow meters now have a very good linearity. Extraordinary results like a linearity of 0.025% band was achieved for one 8" Coriolis master meter. Repeatability was excellent during all the tests; usually well within the requirement of 0.07%. Hydro considers the compact simplified metering station design to be a large improvement and believe this is how numerous liquid fiscal metering stations will be designed in the future. Hydro also expects the design to significantly reduce operating costs.
