Ultrasonic transducer for application in an ultrasonic, flow measuring device or in an ultrasonic, fill-level measuring device

An ultrasonic transducer for measuring flow velocity or volume or fill level of a medium, the ultrasonic transducer comprising:

• a transducer element configured to produce and/or detect ultrasonic signals;
• an acoustic transformer acoustically and mechanically coupled with the transducer element and including a radiating surface and a longitudinal axis, which intersects the radiating surface;
• a housing having a housing body including a housing chamber with a housing wall, the housing wall at least partially surrounding the acoustic transformer, wherein the housing is acoustically and mechanically connected with a measuring tube wall or a container wall;
• and
• a first acoustic insulation disposed within the housing and adapted to be contactable by the medium, wherein the acoustic transformer is connected or connectable mechanically with the housing via a lateral surface of the acoustic transformer using the first acoustic insulation.
