ABSTRACT The present invention is directed to a flowmeter for measur- ing a flow rate comprising a flowmeter body having a hollow and rectangular cross-section and a center axis. The flowmeter body comprises a front wall and a rear wall for defining an expander section therebetween, an inlet nozzle formed at the -front wall, a target having a front surface and an axis, and a throttle portion formed at the rear wall. The front wall and the axis of the target are respectively perpendicular to the center axis of the flowmeter body. The inlet nozzle and the throttle portion have the same axis as the flowmeter body. The flowmeter body is formed so that, in a cross section perpendicular to the target, a circular arc defined by extending from one of the outlet edges of the inlet nozzle tangentially thereto, and passing on an edge of the target on the opposite side of the center axis to the outlet edge, further extends to cross the rear wall. According to the present invention, a fluidic oscillation of high frequency is caused by vortex flows generated behind the target occurs so that measurement of flow rate in a high accuracy is possible at a wide flow rate range.
