Japanese Patent Laid-Open No. 2006-47167 “Quantity Water Mark” JP 2005-273203 A “Water Level Observation Dose Watermark”

However, there have been the following problems in installing conventional water level indicators and water level gauges.
<1> Due to the positional relationship between the water gauge and the board to which it is attached, it is not possible to see the water surface from the shore closer to the installation position. Therefore, the water level is visually recognized and observed by the water gauge. In order to do this, there was an inconvenience such as having to do it from the opposite bank.
<2> The water level indicator and the water level gauge are attached to different locations. Accordingly, since the water level can naturally vary at each location, it is not possible to always measure the water level accurately at the water mark installation position.

<3> The water level gauge is installed directly in the river flow. As a result, the water level gauge can be damaged by the force of the river water flow itself or the collision of drifting objects, and there is always the possibility of breakage or failure.
<4> Therefore, another well is dug on the revetment and a water level gauge is attached to the well. However, in this case, it is unavoidable that there is a difference between the reading of the water gauge and the measured value of the water level gauge because it cannot catch the direct change in the water level, and in the end it will always make accurate measurements. I can't.

  The problem to be solved by the present invention is to provide a water quantity indicator related technology that can visually recognize and observe a water quantity surface from the shore closer to the position of the water quantity indicator, except for the problems of the prior art.
