Abstract: In the method, a portion of the metal tube is placed in a lumen of a metal sleeve having a metal wall surrounding the lumen. The metal tube is placed in such a manner that an outer surface of the metal tube and an inner surface of the metal sleeve at least partially contact one another. The metal sleeve is affixed on the portion of the metal tube placed in its lumen for forming a metal tube, metal sleeve, composite system. The metal tube, metal sleeve, composite system, in turn, is placed in the passageway of the metal body in such a manner that an outer surface of the metal sleeve and an inner surface of the passageway at least partially contact one another, in order thereafter by plastically deforming at least the metal sleeve of the metal tube, metal sleeve, composite system placed in the passageway to form a force interlocking between the inner surface of the passageway and the outer surface of the metal sleeve. The so formed metal tube, metal sleeve, metal body composite system can serve as a component of a measuring transducer, respectively a vibronic measuring device formed therewith.

Abstract: In the method of the invention, a portion of the metal tube is placed in a lumen of a metal sleeve (30) having a metal wall surrounding the lumen. The metal tube is placed in such a manner that an outer surface of the metal tube and an inner surface of the metal sleeve at least partially contact one another. The metal sleeve is affixed on the portion of the metal tube placed in its lumen for forming a metal tube, metal sleeve, composite system (10/30). The metal tube, metal sleeve, composite system (10/30), in turn, is placed in the passageway of the metal body in such a manner that an outer surface of the metal sleeve and an inner surface of the passageway at least partially contact one another, in order thereafter by plastically deforming at least the metal sleeve of the metal tube, metal sleeve, composite system placed in the passageway to form a force interlocking between the inner surface of the passageway and the outer surface of the metal sleeve. The so formed metal tube, metal sleeve, metal body composite system (10/30/20) can serve as a component of a measuring transducer, respectively a vibronic measuring device formed therewith.
Abstract translation: 在本发明的方法中，金属管的一部分放置在金属套筒（30）的内腔中，金属套管（30）具有环绕管腔的金属壁。 金属管被放置成使得金属管的外表面和金属套筒的内表面至少部分地彼此接触。 金属套管固定在放置在其管腔中的金属管的部分上，用于形成金属管，金属套管，复合系统（10/30）。 金属管，金属套管，复合系统（10/30）依次被放置在金属体的通道中，使得金属套筒的外表面和通道的内表面至少部分接触 彼此之间，因此至少通过使金属管的金属套管，金属套管，复合系统至少塑性地变形而形成在通道的内表面和金属套管的外表面之间互锁的力。 这样形成的金属管，金属套管，金属体复合系统（10/30/20）可以分别作为测量传感器的一个部件，分别由其形成的振动测量装置。

Abstract: A measuring tube for a flow measuring means includes an essentially cylindrical measuring tube section that is composed of tantalum on at least the interior surface. At least one insert composed essentially of a noble metal is inserted into one of two end openings such that the interior surface of tantalum is in direct contact with the noble metal. In this way, hydrogen embrittlement of the measuring tube is very easily reduced. Further disclosed is a flow measuring device having a measuring tube of the invention as well as a method for producing such a measuring tube.
