The present invention relates to a flowmeter for measuring the flow rate of fluid and, more specifically, to a turbine flowmeter for measuring the flow rate of fluid by installing a contactless radial bearing in an impeller to prevent the problem of the existing turbine flowmeter on the accuracy of measured flow rate caused by the contact resistance, friction, and wear of a ball bearing. The present invention provides a turbine flowmeter comprising: a flowmeter body (100), a turbine (200), a flow rate measurer (300), and a turbine shaft coupling structure (400). The turbine shaft coupling structure comprises: a supporting part (410) for supporting a turbine shaft; and a fixing part (420). In the turbine flowmeter, a fluid passage is formed inside the supporting part. Also, the fluid passage is formed from the front to the rear surfaces of the supporting part, but is rotated at 0 to 360 degree. |
