PROBLEM TO BE SOLVED: To provide a vortex flowmeter capable of maximizing generation efficiency while minimizing an energy loss.SOLUTION: A vortex flowmeter is equipped with a vortex generating body 3 for generating a vortex in a fluid, a generation device 4, and a measurement processing portion 10. The generation device 4 is equipped with a vibrating portion 9 vibrated by the fluid, and a generating portion 11. The measurement processing portion 10 is equipped with a vibration detecting portion 101 for detecting the vibrations of the vibrating portion 9. The generating portion 11 generates power on the basis of the vibrations detected by the vibration detecting portion 101, and the generation device 4 is provided on the vortex generating body 3 so as to position the vibrating portion 9 within a range in which a variation value of pressure of the fluid is a predetermined value or more. |
