DEVICE FOR OBSERVING WATER LEVEL

摘要

PURPOSE:To eliminate observation errors by sludge deposition and permit remote observation by lowering an agitator by the detection signal of high-tide detector. CONSTITUTION:A float elevating guide 3 is provided to a water level observing device 2 erected in the water bottom, and a spacing part agitator 20 is provided freely elevatably by interposing a spacing (t) between the lower end part of the guide 3 and the bottom part 5 of an observation tower 2. Also, a high tide detector 24 is provided at the intermediate level of a minimum high-tide level 21 and a maximum low-tide level 22. The agitator 20 is lowered from the upper part of the tower 2 to the spacing part (t) by the detection signal of the detector 24.
