Abstract: The flow conditioner comprises a diffusor with a guide system arranged within its lumen, a flow rectifier with a disc shaped flow obstruction arranged within its lumen, wherein the flow obstruction has a plurality of flow openings, as well as a confusor, wherein diffusor, flow rectifier and confusor are connected fluidically in series to form a flow path extending from a flow opening of the diffusor to a flow opening of the confusor and involving the lumina of diffusor, flow rectifier and confusor. The guide system of the diffusor includes a sleeve shaped deflection means as well as a plurality of mutually separated connecting elements connected both with the deflection means as well as with the wall of the diffusor. The guide system is so formed and so positioned that the deflection means is spaced from the wall of the diffusor and arranged coaxially with the lumen of the diffusor.

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.
