| description | PROBLEM TO BE SOLVED: To provide a flowmeter adjusting device capable of easily adjusting the rotating condition of a flow-measuring impeller. SOLUTION: A water meter 1 has a structure in which a flow-measuring axial flow impeller 5 is freely rotatably disposed within first and second interconnected pipes 2, 3. Lugs for adjusting the rotation characteristic of the impeller 5 are formed on the inner peripheral surfaces of the pipes 2, 3 surrounding the impeller 5. The first and second pipes 2, 3 can be rotated relative to each other since they are interconnected by a clamping bolt passed through circumferentially oblong bolt holes 25, 35. Relative rotations of the pipes 2, 3 enable the lugs to be offset relatively and this offset is adjusted to vary the direction of water flow into the impeller 5, thus permitting the rotation characteristic of the impeller to be adjusted to the desired characteristic. The rotating condition of the impeller 5 can thus be adjusted by the simple operation of causing relative rotations of the pipes 2, 3. |
