Claims

[Scope of utility model registration request]

A vortex flowmeter using an optical fiber includes a force receiving body having one end fixed and the other end fixed or supported so that the stress generated inside the body differs depending on disturbance force and measurement force, and the force receiving body. a recess provided at one end; a microbend mechanism disposed at a position within the recess such that stress generated in the force receiving body based on the disturbance force is approximately zero; and a light emitting section at one end. A vortex flowmeter characterized in that the vortex flowmeter comprises: an optical fiber which is connected to the microbend mechanism, has one end sandwiched by the microbend mechanism, and has the other end connected to a light receiving section.
