Ultrasound transmitter and/or receiver system
First Claim
1. An ultrasound transceiver system comprisinga vessel having a wall and containing or conducting a fluid;
- an ultrasound waveguide having an end;
a jacket surrounding said ultrasound waveguide, said jacket having a defined area facing away from said end of the ultrasound waveguide;
an ultrasound transducer located at said one end of the ultrasound waveguide so that the ultrasound transducer can transfer ultrasound waves to, and receive them from, the ultrasound waveguide;
an impedance step between the ultrasound transducer and said defined area of the jacket, said impedance step being constituted by a circumferential groove that extends through the entire thickness of the jacket, and mounting means for at a location on the jacket between the groove and said defined area of the jacket for mounting the jacket to said vessel wall.

Abstract
An ultrasound transmitter and/or receiver/transceiver system includes an ultrasound transducer, an ultrasound waveguide and a jacket, where said ultrasound waveguide is positioned within the jacket, the ultrasound transducer is located at one end of the ultrasound waveguide and at said end of the ultrasound waveguide, the ultrasound transducer can transfer ultrasound waves to, and receive them from, the ultrasound waveguide. An impedance step is provided between the ultrasound transducer and the area of the jacket facing away from the ultrasound transducer. In this fashion, when the ultrasound transmitter and/or receiver system per the invention is installed for instance in the measuring tube of a measuring device, undesirable cross coupling and crosstalk can be sharply reduced.
