Patent ID: 8113047

Claim:
An ultrasound measuring device comprising: an ultrasound transducer for emitting ultrasound signals into a container suited to take up a medium, and for receiving ultrasound signals from the container; a coupling device supporting the ultrasound transducer for forming a coupling, which is suitable for the transmission of ultrasound, between the ultrasound transducer and an external surface of the container; and having an alignment of the ultrasound transducer with respect to the container which is predetermined by the coupling device; whereby the ultrasound transducer is a piezo-electrical thickness-mode transducer; the surface of the ultrasound transducer comprises two planes of symmetry and is provided to be rectangular in shape; the container comprises a cylinder-shaped part; the coupling device is provided for coupling the ultrasound transducer to the external surface of the cylinder-shaped part of the container; and whereby the coupling device, upon coupling of the ultrasound transducer to the external surface of the cylinder-shaped part of the container, provides for asymmetrical alignment of the ultrasound transducer with respect to the container such that the ultrasound transducer and the container have no plane of symmetry in common.
