This paper presents the results of an intercomparison of multiphase flow laboratories. Conducted as part of EMPIR project 16ENG07 – MultiFlowMet II, the primary focus of the investigation was to determine the influence of laboratory-specific factors on the reproducibility of measurements made by multiphase flow metres (MPFMs). To minimise these effects as much as possible, a portable transfer package was designed, including the MPFM, a transparent viewing section, and a straight pipe section with a length of 100 internal pipe diameters. A reproducibility parameter, $\zeta$, was developed to quantify both the reproducibility of the transfer package. Across the three laboratories, metrological compatibility was achieved for the majority of test points. By presenting the $\zeta$ values as functions of the gas volume fraction (GVF) and water liquid ratio (WLR), it was possible to identify flow regimes that may be more susceptible to reductions in reproducibility.

本文介绍了多相流实验室的比较结果。作为EMPIR项目16ENG07 – MultiFlowMet II的一部分，研究的主要重点是确定特定于实验室的因素对多相流量计（MPFM）进行测量的可重复性的影响。为了最大程度地减少这些影响，设计了一种便携式传输包装，包括MPFM，透明观察部分和直管段，其直管段的内径为100。可再现性参数，$\zeta$被开发来量化转移包装的可重复性。在这三个实验室中，大多数测试点都实现了计量兼容性。通过呈现$\zeta$ 值作为气体体积分数（GVF）和水液比（WLR）的函数，可以确定可能更容易降低重现性的流态。
