Abstract
This paper deals with an experimental investigation on the signal qual ity of a hot film anemometer located in the vicinity of a vortex flowm eter exposed to different levels of swirling flow. The results show th at the Strouhal frequency can be identified for swirl indices as large as 0.5. The signal quality remains identical to the zero swirl case f or swirl indices smaller than 0.3 and drops linearly thereafter. As th e swirling flow inhibits the vortex shedding, the signal level reduces and is distributed over a larger frequency bandwidth.
