を特徴とする流量計。 A plurality of cylinder chambers are provided in the housing at equal intervals in the circumferential direction, a flow path is opened at one end of each cylinder chamber, and the other end communicates with the fluid inflow chamber via a switching valve, and A connecting rod having piston heads at both ends that partition the inside and connected to the crankshaft at the center, an inlet opening to the fluid inlet chamber, and a central space provided in the center of the housing and having an outlet opening. In the flow meter that measures the flow rate of fluid passing through the cylinder chamber based on the rotational speed of the crankshaft, the switching valve is provided with a valve seat made of a carbon-copper-phenol resin composition and surface hardened. A part of the flange provided on the valve body is cut out to form an inflow part, a bulging space is provided inside the valve body on the opposite side of the inflow part, and a bulge space is provided inside the valve body on the opposite side of the inflow part. A flowmeter characterized in that a central portion of the seat is a space through which fluid flowing out from each cylinder chamber passes, and a plurality of flow holes are provided around the space in a positional relationship corresponding to the flow path.
