Abstract
A fluidic flowmeter having a reduced diameter pipe portion, a discharge nozzle and an enlarged diameter pipe portion disposed in series in the order of fluid flow direction, a pair of control nozzles formed on a boundary between the discharge nozzle and the enlarged diameter pipe portion and oriented substantially normal to the discharge direction of the discharge nozzle, the control nozzles facing each other, a pair of return flow passages connecting between the respective control nozzles and a downstream side of the enlarged diameter pipe portion, a target for stabilizing switching of fluid flow direction at the enlarged diameter pipe portion, a flow amount measuring sensor for detecting a variation in pressure or flow amount due to a variation in the flow direction of discharged fluid from the discharge nozzle, a pair of first partition walls for sectioning the enlarged diameter pipe portion, the control nozzles and the return flow passages, a second partition wall for forming discharge passages together with the first partition walls. A face of the target directed towards the discharge nozzle is positioned between a straight line interconnecting center portions of outer peripheral faces of the first partition walls and another straight line interconnecting leading edges of the first partition walls at the control nozzle side.
