Abstract
A vortex flowmeter is disclosed, which includes, among other features, a closed measuring tube, through which a flowable medium that is to be quantitatively measured flows, the medium flowing against a disturbing element that is arranged in the measuring tube. A vibration sensor is arranged downstream in the direction of flow detecting the vortex frequency generated by the disturbing element. An electronic evaluation unit is disposed downstream of the vibration sensor converting it into an electric signal corresponding to the quantitative flow rate or volumetric flow rate. The relative position can be changed between the measuring tube and the disturbing element and/or the measuring tube and the vibration sensor in a signal-optimizing manner.
