Abstract

PURPOSE:To enable the instrumental error regulation to be readily performed by simply turning an annular ring, by providing the inner case outer wall with an annular ring which can vary the sectional area of the holes provided in the inner case. CONSTITUTION:An upper inner case 22 in which an impeller 2 is enclosed, and a lower inner case 23 in which a rectifying blade 18 is secured are provided inside water meter through which tap water flows. In the impeller 2 enclosing portion at the lower end portion of the upper inner case 22, a plurality of holes 24 for branched flow paths are provided on the same plane. An annular ring 26 having holes 25 at the positions corresponding to these holes 24 for branched flow paths is fitably attached to the upper inner case 22. By said constitution, when the annular ring 26 is rotated to vary to sectional areas of the holes 24 for branched flow paths, a portion of tap water flows out of the inner case 21 through the branched flow paths. Accordingly, the instrumental error regulation of the water meter is made possible.
