<p>The present invention relates to a water gauge and, more specifically, to a water gauge to be installed in an area of where the temperature of water falls below the freezing point. Therefore, according to the present invention, a deceleration gear unit is configured to include an upper gear space reduction protrusion or a lower gear space reduction protrusion, thereby it is possible to reduce the possibility of freezing of deceleration gear unit when water in a meter body portion is frozen and to stably maintain the initial installation state of a reduction gear. When the water inside the meter body portion is frozen, it is possible to reduce the possibility of freezing of the deceleration gear unit and to stably maintain the initial installation state of the reduction gear.</p> |
