Abstract
An ultrasonic transducer as an important part of an ultrasonic flow meter is described, with a transducer housing and with a transducer element, the transducer housing having an ultrasound window and a housing tube, the transducer element being made for sending or receiving ultrasonic waves and being either near the ultrasound window of the transducer housing or away from the ultrasound window of the transducer housing, there being a relatively soft mechanical coupling system and the mechanical coupling system having preferably at least one weakly coupled mechanical resonator. The ultrasonic transducer is improved with respect to the prevention of the transmission of housing waves by there being a second soft mechanical coupling system.
