Abstract
In the particular embodiments of the invention described herein, a Karman's vortex flow metering apparatus has an oscillating plate magnetically held at the vertex of a triangular chamber located outside a flow line. Within the flow line a Karman's vortex generator is mounted transverse to the flow direction and has vortex generating slits extending along its length. Pressure detecting slits located at the end of the generator near the detector communicate through short pressure transmitting lines with opposite sides of the chamber. The resulting oscillation of the plate is detected optically or magnetically to provide signals corresponding to the flow rate.
