Abstract

A flow metering apparatus is disclosed which includes a dust in which a fluid to be measured flows, a pillar-shaped vortex generator inserted into the duct, and a force detector fixed firmly to the vortex generator substantially in an integrated manner, and capable of directly detecting an alternating force applied to the vortex generator due to Karman's vortex generated by the vortex generator, and converting the alternating force into an electric output signal.
