Claims

[Claims for Utility Model Registration] A flapper that is disposed inside a pipe and has a plate of a size that substantially closes the pipe, and has both ends of one side of the plate rotatably supported at a predetermined position of the pipe. , a window provided at a predetermined position of the piping for visually observing the flapper; and a flow rate scale displayed on the window and calibrated in accordance with the inclination angle of the flapper that changes depending on the flow rate of the fluid flowing in the piping. The flapper type flowmeter is characterized in that the flapper is provided with a biasing means for biasing the flapper in a direction opposite to the tilting direction caused by the fluid to suppress the tilt angle of the flapper. Flapper type flowmeter.
