Claims

[Scope of Claim for Utility Model Registration] A large-diameter pipe communicating in a direction perpendicular to the pipe wall of the pipe through which the fluid to be measured flows, a block provided at the free end of the large-diameter pipe, and a block movably supported by the block. a movable tube supported at the axis of the large diameter tube; a pitot tube attached to the tip of the movable tube with its tip protruding into the flow path within the tube; and a hole formed in the wall of the movable tube. and a valve formed by a hole formed in the block; a filter storage chamber formed in the block and downstream of the valve; and a filter storage chamber that is stored in the filter storage chamber to filter fluid passing through the valve a strainer configured with a filter body, and a taper whose lower end communicates with the filter body storage chamber and whose diameter gradually increases toward the upper end,
a tapered pipe installed on the top surface of the block; a float housed in the tapered pipe that rises to a position corresponding to the flow pressure of the fluid applied through the valve and displays the flow rate of the fluid to be measured flowing through the pipe; A pitot tube flowmeter comprising: an outflow pipe communicating with the upper end of the tapered pipe and having a lower end communicating with the large diameter pipe; and a knob extending from the movable pipe for opening and closing the valve.
