Abstract
A water meter of the present invention may accurately measure a flow rate and reduce power consumption. The water meter includes a body including an inlet unit and an outlet unit, an impeller unit provided to rotate due to a fluid flowing in the body, a cover member that covers one side of the impeller unit and includes a guide groove formed therein, and sensors that are provided on one side and the other side of the cover member and are spaced apart from each other to face each other. The impeller unit includes blades interfering with the fluid, a shaft forming a rotational center of the blades, and a cut-off unit that extends from one side of the plurality of blades to be inserted into the guide groove, and selectively cuts off signal transmission between the plurality of sensors.
