Summary

Ruhrgas tested vortex shedding meters at its Lintorf high-pressure flow metering test rig and in field stations, where they were installed in series with turbine meters. The results showed that vortex meters type-approved in Germany are not yet fit for custody transfer metering, and are only used as check meters at Ruhrgas metering stations. Laboratory tests of a Bopp & Reuther vortex meter at the Lintorf test rig found a fairly horizontal calibration curve with an error of approximately +0.5% from the reference flow, but with resonance peaks at certain flow rates. Field tests of RvG vortex meters installed in series with turbine meters also showed similar results. The tests demonstrated that the vortex meter and straight upstream piping, including a flow straightener, must be treated as one package for calibration and field installation.
