Claims

[Scope of utility model registration request]

An introduction path connected upstream of an orifice provided in the conduit, an arc-shaped pressure chamber whose inlet is connected to the introduction path, and a fluid pressure chamber that forms the inner circumference of the pressure chamber. an outer ring portion having first slits provided at an acute angle to the circumferential flow direction and second slits provided at a right angle to the circumferential flow direction; and an arc-shaped vortex chamber inside the outer ring portion. an inner ring part having a third slit at a right angle to the circumferential flow direction of the fluid vortex chamber at a position corresponding to the first and second slits and spaced apart from each other to form an inner ring part; an absorption chamber formed inside; an outflow path connecting the absorption chamber to the downstream side of the orifice; a ball disposed within the vortex chamber and movable by the flow of fluid; A flowmeter comprising: a detection element that detects passage of a ball; and a flow rate measurement and display device that measures and displays a flow rate based on a signal from the detection element.
