A supplementary comparison, COOMET.M.FF-S2, in the field of water flow was organized by the COOMET Technical Committee (TC) 1.4 Flow Measurement. The goal of the comparison was to confirm the calibration and measurement capabilities (CMC) of the participating national metrology institutes (NMIs) in the flow ranges between 0.5 m 3 /h and 5.0 m 3 /h, and, respectively, between 20.0 m 3 /h and 100.0 m 3 /h. This is the first comparison in the field of fluid flow which has been done by the COOMET TC Flow Measurement. This report describes the comparison results of the following water flow facilities (NMIs): PTB (Braunschweig, Germany), National standards Centre of the Republic of Uzbekistan (Tashkent, Republic of Uzbekistan), LEI (Kaunas, Lithuania), SMU (Bratislava, Slovakia), BelGIM (Minsk, Belarus), VNIIR (Kazan, Russia). The PTB was designated as the pilot lab of this comparison, due to the low measurement uncertainty of its wate...

关于液流国家标准COOMET.M.FF-S2补充比较的最终报告（COOMET项目406 / UA / 07）

COOMET技术委员会（TC）1.4流量测量组织了在水流量领域的补充比较，COOMET.M.FF-S2。比较的目的是确认参与的国家计量机构（NMI）在0.5 m 3 / h和5.0 m 3 / h之间以及分别在20.0 m 3之间的流量范围内的校准和测量能力（CMC） / h和100.0 m 3 / h。这是通过COOMET TC流量测量完成的流体流量领域的首次比较。本报告描述了以下水流设施（NMI）的比较结果：PTB（德国不伦瑞克），乌兹别克斯坦共和国国家标准中心（乌兹别克斯坦共和国塔什干），LEI（立陶宛考纳斯），SMU（布拉迪斯拉发，斯洛伐克），BelGIM（白俄罗斯明斯克），VNIIR（俄罗斯喀山）。
