Resonant flow sensor and uses and production methods for the same

摘要: The invention relates to a flow state sensor ( 10 ) for detecting at body 16 that may be impinged on by 12 ). A is of simple construction and evaluate characterised in accordance with the least one frequency device 20 predefined characteristic state. has oscillation element 22; 22 , b c excitable resonant oscillatory movement 30 having or natural adapted characteristic, especially corresponding characteristic. Uses measuring 62 method, an advantageous production method are also proposed.
