Installation effects on multi-path ultrasonic flow meters: The {open_quote}ULTRAFLOW{close_quote} project
{open_quote}ULTRAFLOW{close_quote} was a Joint Industry Project aimed at establishing the effect of installation conditions on multi-path ultrasonic flow meters. An extensive test series was performed at 5 test facilities on 6 inch and 12 inch meters operating on natural gas at pressures from 10 to 60 bar. All test facilities and procedures are reviewed by an independent international Quality Assessment Team, comprising experts from legal metrological authorities, to ensure that the work was appropriate to support International Standards activity. This paper is a condensed version of the projects final report describing the project and test results. The tests in ideal flow conditions pay attention to meter stability and effects of signal averaging and pressure. From the error shifts in the tests with upstream disturbances (1 or 2 bends, step changes in pipe diameter and pressure reduction) values for uncertainties due to the presence of these disturbances are proposed.
