are formed in series in the flow direction, and a pair of control nozzles 6a and 6b are provided at the boundary between the jet nozzle 3 and the expanded pipe section 5, oriented in a direction substantially perpendicular to the jet direction of the jet nozzle 3. A pair of return flow passages 7a and 7b are formed to face each other and connect the control nozzles 6a and 6b to the downstream side of the expanded pipe section 5, so that the flow from the jet nozzle 3 is The fluidic flowmeter is equipped with a flow rate measurement sensor 14 that detects a change in pressure or flow rate caused by a change in flow direction of a jet flow, and the pipe expansion section 5
A pair of partition walls 8a, 8b that define the control nozzles 6a, 6b and the return flow paths 7a, 7b are provided with an outer peripheral surface in the shape of a half cylinder or a substantially half cylinder, and the outer peripheral surface of the partition walls 8a, 8b is Of these, the flat portion 19 or the curved surface portions 17 and 20 with a large radius of curvature are connected to the conduit expansion section 5, and the curved surface portion 18 with a small radius of curvature is connected to the return flow paths 7a and 7b and the control nozzle 6.
Fluidic flowmeters are installed at a and 6b, respectively.
