Summary Report of NIST's Industry-Government Consortium Research Program onFlowmeter Installation Effects with Emphasis on the Research Period May 1989-February 1990: Tube Bundle Effects

摘要

The report presents results produced in a consortium-sponsored research programon flowmeter installation effects. The project is a collaborative one that has been underway for four years; it is supported by an industry-government consortium that meets twice yearly to review and discuss results and to plan subsequent phases of the work. The report contains the results and conclusions of the recent meeting of this consortium at NIST-Gaithersburg, MD in February 1990. The objective of the research program is to produce improved flowmeter performance when meters are installed in non-ideal conditions. The objective is being attained via a strategy to (1) measure, understand, and quantify the salient features of non-ideal pipe flows from such pipeline elements as elbows, reducers, valves, flow conditioners, etc. or combinations of theses, (2) correlate meter-factor shifts for selected types of flowmeters, relative to the features of these non-ideal pipe flows so as to be able to predict meter performance accurately in non-ideal installations, and (3) disseminate the resulting technology through appropriate channels such as publishing the results in pertinent journals and upgrading paper standards for flow measurements.
