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.
