Abstract
The invention relates to a flow state sensor () for detecting a flow state at a body () that may be impinged on by a flow (). A flow state sensor () that is of a simple construction and that is simple to evaluate is characterized in accordance with the invention by at least one frequency detecting device () for detecting at least one predefined frequency characteristic of the flow state. The frequency detecting device () has at least one oscillation element () excitable to resonant oscillatory movement () by a flow () and having a resonant frequency or natural frequency adapted to the predefined frequency characteristic, especially corresponding to the predefined frequency characteristic. Uses of the flow state sensor () in a flow measuring device () and in a flow measuring method, and an advantageous production method for the flow state sensor () are also proposed.
