Claims

[Scope of utility model registration request]

An impeller installed in the middle of the flow path of the fluid to be measured and rotated by the fluid to be measured, a rotating shaft connected to the impeller so as to take out the rotation of the impeller to the outside, and an impeller located in the middle of the rotating shaft. a brake blade provided to prevent over-rotation of the impeller; a brake blade chamber containing fluid that provides resistance to rotation of the brake blade; and a lower end portion of the rotary shaft communicating with the brake blade chamber. a shaft sealing chamber surrounding the shaft; a magnet positioned within the shaft sealing chamber and attached to the rotating shaft to constitute a magnetic coupling; and the brake having one end attached to the rotating shaft and the other end passing through the rotating shaft. A flow meter consisting of a skirt section that is deployed close to the bottom surface of a blade chamber to prevent dust from entering.
