<p>The present invention relates to a stainless water meter having pressure difference adjustment and backflow prevention functions. According to the present invention, a display error between a water inflow amount of a water meter and a water use amount displayed by impeller rotation can be easily adjusted outside a body section while discharge water backflow can be prevented. The present invention includes the body section (100) including a lower housing (110) that is provided with an accommodating space (101) with an open upper side therein and is provided with water inlet (111) and a water outlet (113) on both sides and an upper housing (120) that is coupled with an upper portion of the lower housing (110) to seal the opening; and a backflow prevention unit (400) and is pivotally hinge-coupled with an upper side in the water outlet (113) so as to block a flow path hole (113a) of the water outlet (113) during water backflow. According to the present invention, a pressure difference adjustment unit is provided outside the water inlet of the water meter so that the display error between the water inflow amount and the water use amount displayed by the impeller rotation can be easily adjusted outside the body section and the backflow prevention unit is provided in the water outlet so that the discharge water backflow can be prevented. Also, airtightness and watertightness can be improved.</p> |
