  • Measuring Volume Flow (AREA)

Abstract

PURPOSE: To obtain a water service meter which can determine precisely the amount in the case of the small amount of flow, by providing a partition wall in order to make narrower the flow passage between an inlet passage and an outlet passage in a part of a vane wheel chamber.
CONSTITUTION: There are provided a plurality of entrance passages 11b and exit passages 11a at regular interval on an outer periphery of a lower inner case accommodating a vane wheel 12 therein and at an intermediate portion, there is formed protrudingly a partition wall 11c from the internal face of a lower inner case 11 toward a center of the vane wheel so as to make narrower the flow passage of the water service. Further, on a lower surface of the lower inner case 11 and a lower surface of an upper inner case 10, radially extending ribs 15, 17 are formed. Thus, the water service water passing through the entrance passage 11b strikes effectively against the vane wheel to rotate it without flowing along the internal surface of the lower inner case 11, so that in the case of the small amount of flow, the present meter can measure the flow without the deterioration thereof.
