| Zusammenfassung: | A fluidic flow meter of an oscillating jet type is disclosed wherein a jet of fluid discharged from an elongate jet-forming orifice is caused to oscillate in a plane transversely of the plane of the orifice with the rate of oscillation of the jet being measurable as an indication of the flow rate through the meter. The flow meter comprises a flow conditioning means comprising a bluff body which is positioned upstream of the jet-forming orifice and is effective under laminar and transitional inlet flow conditions being to flatten the velocity flow profile and to introduce turbulence into the flow whereby turbulent flow conditions are simulated at the orifice |
