Advances in Coriolis mass flow metering research and technology

Coriolis mass flow metering is known to be accurate for steady,single phase flows.Current research within the UK is examining the dynamic response of coriolis meters and improving their two-phase flow performance. In joint research between the Univerisities of Brunel and Oxford, the sources of measurement delay have been analysed,and a new transmitter has been developed with a deadtime of 16ms.High measurement precision allows short batching of <0.4s duration with 1% repeatability. Two-phase flow research between the Universities of Cranfield and Oxford have produced a coriolis meter which can maintain operation at high levels of gas void fraction (GVF).On-line techniques have been developed to provide corrections to mass flow and density errors.
