Abstract
A measurement system includes: a pipe insertable into the course of a pipeline; a bluff body arranged in the pipe and configured to generate vortices having a shedding frequency dependent on an instantaneous flow velocity of a fluid such that a Kármán vortex street is formed in the fluid flowing downstream of the bluff body; a vortex sensor arranged downstream of the bluff body, having a resonance frequency and configured to effect mechanical oscillations as to provide a vortex sensor signal including a first component representing oscillations of the vortex sensor with the shedding frequency and a second component representing the mechanical resonance frequency of the vortex sensor; and converter electronics for evaluating the vortex sensor signal and configured to determine whether and/or to what extent the fluid contains foreign substances and/or is a single- or multi-phase substance based on the first and second components of the vortex sensor signal.
