The flow performance of the Micro Motion Coriolis meters has been certified by third party measurement verification laboratories including US-based National Institute of Standards and Technology (NIST) and the European Organization for Nuclear Research (CERN).
Emerson Process Management (EPM) said LNG industry users had reported increased throughput, availability and up-time as a result of using Micro Motion Coriolis meters as cryogenic mass flowmeters in transfer applications.
The devices can be used with Emerson’s PlantWeb digital plant architecture to leverage the meters’ patented multivariable digital signal processing technology (MVP), and address measurement and operational requirements unique to LNG transfers.
EPM said the MVD technology allowed the device to measure mass flow, density and temperature of the flowing fluid directly, using patented algorithms to achieve and maintain superior meter performance at cryogenic temperatures.
This eliminates the requirement to establish methods of verifying calibration performance on cryogenic fluids as is necessary with alternative, volumetric metering techniques, according to EPM.
EPM said the independent certification supported the data it had received from over ten years of LNG measurement in applications such as high-capacity rundown flows in Alaska, custody transfer in Australia and cryogenic process control in France.
