Coriolis mass flow metering for three-phase flow: A case study

► A three-phase metering skid is described, based on Coriolis Mass Flow and Water Cut metering. ► Formal trials have taken place at the UK National Flow Laboratory, NEL. ► The water cut ranged from 0 to 100% and the gas volume fraction ranged from 0 to 50%. ► The liquid mass flow error was within ±2.5%, and the gas mass flow error within ±5.0%. ► The oil mass flow error was ±6.0% for water cuts less than 70%.
