Abstract

In a Karman vortex flow meter, a first space section is provided between a detection section and an inflow opening, and a second space section is provided between the detection section and an outflow opening. The first space and the second space have cross-sectional areas larger than a cross-sectional area of the detection passage. Accordingly, a disorder of a fluid coming in the inflow opening of the detection passage and pulsation components coming from the outflow opening are reduced by the first and second spaces.
