Abstract

A measuring transducer comprises: a housing, with an inlet-side flow divider having four flow openings, and an outlet-side end having four flow openings; a tube arrangement having four tubes connected to the flow dividers; and a first coupling element. An exciter mechanism for producing and/or maintaining mechanical oscillations of the four measuring tubes. The first coupling element includes a deformation body and four connecting struts, of which connected with a first strut end and with the first measuring tube, a second connecting strut is connected with a first strut end and with a second strut end with the second measuring tube, a third connecting strut and with a second strut end with the first measuring tube, and a fourth connecting strut is connected with a first strut end and with a second strut end with the fourth measuring tube.
