    摘要: An intake air flow rate detector of an internal engine using a Karman vortex sensor, wherein the mass flow rate is obtained by detecting a volumetric flow rate by the Karman vortex sensor and a dynamic pressure or differential pressure at upstream and downstream of the sensor by a strain gage mounted on a partition in a closed chamber. Density compensation of the flow of air is effected only taking said measurement values at a standard range in which the Karman vortex is stable and the differential pressure has a large value.

    摘要: A semi-cylindrical body member with a flat section is disposed in a fluid flow conduit in an arrangement to allow the surface of the flat portion to face upstream. Means for counting the number of Karman vortexes created by the body member under flowing of the fluid is disposed in the body member.
