Abstract

A vortex flow measuring device for monitoring and/or measuring an, at least at times, two phase medium flowing in a pipeline; wherein the medium has a first phase, especially a gaseous, first phase, with a first density and a second phase, especially a particle or droplet shaped, second phase, having a second density different from the first density; and wherein the vortex flow measuring device has at least a measuring tube, which can be inserted in a pipeline, a bluff body, and a vortex sensor, which responds to pressure fluctuations. The vortex flow measuring device additionally includes an acoustic transducer, which is formed integrally in a component, especially the bluff body, which protrudes into a flow path within the measuring tube, or is acoustically coupled to such component in such a manner that acoustic signals produced by impact of particles and/or droplets of the second phase on the component are transducible to electrical signals by the acoustic transducer.
