Abstract
An ultrasonic transducer for an ultrasonic flow meter, with a transducer housing, with a transducer element for generating and/or for receiving ultrasonic signals and with an emitting element, the emitting element being exposed to ultrasonic signals at least indirectly from the transducer element and emitting the ultrasonic signals via one end face on one front side of the emitting element into the vicinity bordering the ultrasonic transducer and/or the emitting element picking up ultrasonic signals from the vicinity via one end face on one front side of the emitting element and transmitting them at least indirectly to the transducer element. A good directional action in spite of small dimensions is achieved by the emitting element being connected to the transducer housing via a connecting element and being free standing on its periphery on the front side such that it can oscillate freely on the periphery.
