Flowmeter
First Claim
1. A flowmeter, with a measuring tube, an ultrasound transducer, an ultrasound waveguide and a seal, said ultrasound transducer connecting outside the measuring tube to the ultrasound waveguide in such fashion that ultrasound waves generated by the ultrasound transducer are transferred to the ultrasound waveguide and, conversely, ultrasound waves received by the ultrasound waveguide are transferred to the ultrasound transducer, said ultrasound waveguide protruding at least partly into the measuring tube, whereinthe seal is positioned between the ultrasound waveguide and the measuring tube, and the seal is pressure-loaded in a vertical direction relative to the plane of the seal.

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.

9. A flowmeter, with a measuring tube, an ultrasound transducer, an ultrasound transducer mount and a seal, said ultrasound transducer being attached to the ultrasound transducer mount, and the ultrasound transducer mount at least partly protruding into the measuring tube in such fashion that ultrasound waves generated by the ultrasound transducer are transmitted via the ultrasound transducer mount into a fluid flowing through the measuring tube and, conversely, ultrasound waves received from the fluid are transferred via the ultrasound transducer mount to the ultrasound transducer, wherein
the seal is positioned between the ultrasound transducer mount and the measuring tube, and the seal is pressure-loaded in a vertical direction relative to the plane of the seal.
-
11. The flowmeter as in 9 or 10 wherein the pressure-loading is accomplished by means of a set of spring washers.
