System for measuring mass of flowing medium

摘要

The system has a flow rectifier (20) with a tube (28), which has several fixing elements displaced with respect to each other at a specified distance. The wires (31,33) of the wire grid (21) are so held, that the wire grid has a configuration fixed to the web (27) of the flow openings (24) of the flow rectifier. The fixing elements at the tube may be slits, projections or drillings.
