Abstract

A flow measurement arrangement and measuring transmitter for process instrumentation that includes the flow measurement arrangement, wherein the flow measurement arrangement operating in accordance with the differential-pressure method includes a tube and an elastically deformable measuring diaphragm (orifice plate) arranged in the cross section of the tube and a strain sensor that detects the deformation and converts it into an electric signal, where the measuring diaphragm (orifice plate) and the tube are formed in one piece from uniform material, and where both side of the measuring diaphragm (orifice plate) each pass into the tube via a fillet groove and the at least one strain sensor is arranged on the circumferential side of the tube opposite the fillet groove.
