Abstract
A method for monitoring and/or measuring an, at least at times, two-phase medium flowing in a pipeline, and having a first phase, especially a gaseous first phase, with a first density and a second phase, especially a liquid second phase, having a second density different from the first density. The method is performed with a vortex flow measuring device, which has at least one measuring tube inserted into the pipeline, a bluff body and a vortex sensor. In such case, the vortex sensor includes a sensitive section that responds to pressure fluctuations, and that is arranged at least partially adjoining the wall of the measuring tube. In the method, a wall flow of a second phase of a two or more phase medium is detected by the vortex flow measuring device, when a measurement signal which contains characteristic features for an interaction of a wall flow of the second phase of a flowing medium flowing along a wall of the measuring tube with the sensitive section of the first vortex sensor is registered by the vortex sensor.
