A coupling apparatus of a water gauge is provided to prevent leakage by adjusting the gap between a cap and an elbow pipe with turning a fixing member, and to install and replace the water gauge conveniently by forming a protruded part in the cap. A water gauge(50) is installed between a supply pipe(80) and a discharge pipe(90), and a movable coupler(20) is connected to the supply pipe to movably install a valve(30) regulating water. A body(10) includes a guide groove(11) guiding the movable coupler, a female screw(12) and a fixing connector(13). A fixing member(70) is combined with the female screw of the body, and connected to the movable coupler to move the movable coupler along the guide groove. A cap(40) is installed between the valve and the water gauge, and a protruded part(41) is formed in an upper part of the cap to accurately install the water gauge. |
