Abstract

The invention relates to a vortex flowmeter for detecting the quantity of liquid or gaseous media passed in conduits that have a circular cross-section. The aim of the invention is to improve a flowmeter of the above-mentioned kind so that its measuring accuracy is substantially improved while reducing the inlet and the outlet distance. For this purpose, at least two vortex generators (10) evenly distributed across the measuring cross-section detect asymmetric speed distributions across the measuring cross-section. The height/width ratio HWE/BWE of said vortex generators is ≤ 4 and they are provided in guide channels (2) that subdivide the cross-section of flow. Said guide channels extend in the axial direction by at least 0.5 D (conduit inner diameter) at both sides of the vortex generators and are formed by guide walls (5, 7) disposed substantially in parallel to the vortex shedding edges (12 15) and limiting walls (3) interlinking said guide walls, and the vortex generators (10) extend from limiting wall (3) to limiting wall (3).
