Claims

[Scope of utility model registration request]

In a flow meter that detects the flow rate of a fluid to be measured by the rotation of an impeller, the blades of the impeller are mounted so as to be swingable about the rotation axis of the impeller, and the blades are swingably attached to the rotation axis of the impeller. A regulating mechanism is provided for regulating the range of movement, and when the fluid to be measured flows in one direction, the vane swings in one direction and receives a rotational force, and when the fluid to be measured flows in the other direction, the vane swings in one direction. A flowmeter characterized in that it swings to the other side so that it does not receive rotational force.
