Exemplary embodiments relate to a vortex flowmeter having a vortex body which projects into the flowing measurement medium in a measuring tube, a sensor for detecting the vortex frequency being connected downstream of said vortex body in the direction of flow and being provided with means for measuring the temperature of the measurement medium, and a downstream electronic evaluation unit determining the flow rate in a temperature-compensated manner, the sensor including a carrier body on which a plurality of piezoelectric elements, which are arranged at a distance from one another and are intended to measure the frequency, and a temperature-measuring element are placed.

Vortex flowmeter with optimized temperature detection

A method is disclosed for producing a connection between a measuring tube and at least one flange, e.g., in the case of a Coriolis mass flowmeter. In order to ensure reliable connection of the components in this case, the measuring tube can be inserted at one end over a portion through a flange bore, such that it projects out of the bore on the other side, and that the projecting end be flared out over the sealing face of the flange.
