| Zusammenfassung | Flow sensors are exposed to very disparate and usually adverse flow conditions produced by the pipe configuration at the installation location. These so-called installation effects may affect the accuracy of the flow measurement. Within performance tests of water, heat, and cooling meters at flow laboratories, a selection of such installation effects are emulated by standardized disturbance generators. In particular, the standardized swirl disturbance generator is designed to reproduce the flow conditions downstream from a double-bend out of plane, a common installation in realistic pipe networks. However, recent studies suggest that tests with standardized swirl disturbance generators might not be sufficiently reproducible due to instabilities generating random flow patterns downstream. Here, we analyze the flow profile generated by a novel asymmetric swirl disturbance generator and a double-bend out of plane using laser-Doppler velocimetry. Our results suggest that the asymmetric swirl disturbance generator produces flow disturbances with similar features as those Downstream from a double-bend out of plane. In consequence, the asymmetric flow disturbance generator is a good candidate for more reproducible and realistic tests of installation effects at flow laboratories and shall replace the current swirl generator in the standards. |
