[…] ure meters. The flowrate of the liquid, which can be a combination of water and hyd rocarbons, is normally determined by an external means such as from test s eparator data, tracer experiments or sampling etc. Information on the liquid flowrat e and density is necessary to use the correlations. The majority of commercial […] … Continue reading

[…] Introduction This paper was conceived after an incident that made clear to me that there is a misunderstanding of transition and laminar flow. A USM was being tested in the Reynolds number range of 6000 to 10000 on oil and the meter was very noisy, with a high standard deviation (turbulence) output. The manufacturer […] … Continue reading

[…] reservoirs. Many oil companies have been actively pursuing the development of such metering systems, either through Joint Industry Projects or through their own research and by making test facilities available. These efforts, together with the expertise and the perseverance of the equipment suppliers, have led to the appearance of first-generation multiphase metering systems on […] … Continue reading
