APPARATUS AND METHOD OF MEASURING A FLOW WITHIN A METER

摘要

The present invention relates to a water meter, and more particularly, to a water meter which may measure an accurate flow therein and reduce power consumption. The water meter includes: a main body part including an inlet and an outlet; an impeller unit which is rotatable by a fluid flowing into the main body part; a cover member covering one side of the impeller unit, the cover member having a guide groove; and a plurality of sensors provided at one side and the other side of the cover member, the plurality of sensors being spaced apart and facing each other. The impeller unit includes: a plurality of blades interfering with the fluid; a shaft providing a rotation center of the blades; and an interruption part extending toward one side of each of the blades and inserted into the guide groove, the interruption part selectively interrupting transmitting/receiving of a signal between the plurality of sensors.
