WITHDRAWN: Inter-laboratory comparison results for Coriolis mass flowmeter calibration facilities

Inter-laboratory comparison testing is fundamental to assuring the accuracy of a laboratory’s stated measurement uncertainty, and a requirement for accreditation to ISO/IEC 17025:2005. Inter-laboratory comparisons using Emerson’s Micro Motion® ELITE® Coriolis mass flowmeters support the claimed mass flow uncertainties of 0.014% (k=2k=2) for the high-accuracy liquid mass flow calibration facilities, and 0.03% (k=2k=2) for the production and service mass flow calibration facilities. This paper describes multiple calibration methodologies, international traceability to National Metrology Institutes, test results and future design requirements of an inter-laboratory test program required to support multiple, accredited flow calibration centers around the globe.
