ABSTRACT:
A vortex fluid flowmeter adapted to measure the flowrate of fluid passing through a conduit by measuring the frequency of emission of alternating vortices generated by an obstacle extending across the conduit, comprises a mesh structure mounted upstream of the vortex-shedding obstacle. Said mesh structure is constituted by a grid made of bars of wires of rectangular cross-section. The distance between the grid and the obstacle is so chosen that the obstacle be in the efficient working range of the grid.
