Abstract

The present disclosure relates to a transducer comprising a tube, a converter unit, an electromechanical exciter arrangement for stimulating and sustaining forced mechanical vibrations of the converter unit, and a sensor arrangement for detecting mechanical vibrations of the converter unit and for generating a vibration signal representing mechanical vibrations of the converter unit. The converter unit includes two connection elements connected to a displacer element and is inserted into the tube and connected thereto. The converter unit is configured as to be contacted by a fluid flowing through the tube and enabled to vibrate such that the connection elements and the displacer elements are proportionately elastically deformed. The transducer can be a constituent of a measuring system adapted to measure and/or monitor a flow parameter of the flowing fluid and further includes an electronic measuring and operating system coupled to the exciter arrangement and the sensor arrangement of the transducer.
