Abstract

A special fluid flow diverter was developed and tested for the new water flow standard facility which is under construction now at PTB Braunschweig. It offers several new features and properties for improving the accuracy, e. g. variable rec- tangular nozzle, CFD designed influx pipe section and high precision electrome- chanical switching device. The paper describes design and test results of a first pro- totype in a water flow circuit.
