| 摘要 |
The invention relates to a coupling element (K) for an ultrasonic flowmeter, comprising several segments (Si), which are separate from one another and run from a contact plane (KE) for a piezoelement (P) to a base plate (G). According to the invention, the length of the individual segments (Si) is measured in such a way that ultrasonic waves are emitted from, or received by the base plate (G) at a certain angle alpha . |
