Abstract

A device for measuring the mass of a flowing medium has a measuring element disposed in a measurement fitting. A flow rectifier that is provided upstream of the measuring element has flow openings that are separated from one another by intermediary pieces. A wire lattice is fastened to a tube of the flow rectifier extending in the direction of the measuring element. The tube of the flow rectifier has a number of fixing elements disposed offset from one another at a predetermined distance in which wires of the wire lattice are secured so that the wire lattice has a fixed configuration in relation to the intermediary pieces of the flow openings of the flow rectifier.
