Weight aqueous standard that can record the highest water level of the river

摘要

The present invention on the outer crest without providing a structure such as steel H, it is possible to water management in the river, together check the water level in the visual inspection or monitoring camera, provides an apparatus which can record the history of the maximum water level to. A installed in the inclined slope such as embankments slopes and embankment slopes, and paste printing or sheet a scale for reading the current water level in the front cover of the device of a hollow box-formed of a metallic material or a plastic material and displaying at, as well as used as a weight aqueous preparation, inside the hollow box-guide for the float and the float moves up and down is provided, the float rises when the water has penetrated the interior of the box making, the water level When you dropped the float stopped on guide of the location of the highest water level, it is possible to record the highest water level, the box-front bottom, the scale of the beam printing or sheet in conjunction with weight aqueous target are displayed, this by the highest It reads the water level. .BACKGROUND
