Abstract
A flowmeter includes a measuring tube, an ultrasound transducer, an ultrasound waveguide and a seal. The ultrasound transducer connects outside the measuring tube to the ultrasound waveguide, the ultrasound waveguide protruding at least partly into the measuring tube, in such fashion that ultrasound waves generated by the ultrasound transducer can be transferred to the ultrasound waveguide and, conversely, ultrasound waves received by the ultrasound waveguide can be transferred to the ultrasound transducer, The seal is positioned between the ultrasound waveguide and the measuring tube. This reduces cross coupling while at the same time enhancing the flow pattern.
