ABSTRACT:
A cylindrical vortex generator of a Karman shedding flow meter is set in an inlet tube of an air cleaner of a combustion engine. An air flow uniforming device such as a wire netting is disposed in the inlet tube at a position upstream of the vortex generator for producing in the inlet tube a turbulent but considerably uniformed air flow directed toward the vortex generator. A bypass means is arranged in the inlet tube to make a bypass flow of air directed toward the vortex generator when the combustion engine is under high speed operation.
