The water depth in the reservoir is measured by water level benchmarks. Water level measurement can provide data for water conservancy, water transportation, flood control, waterlogging prevention, power generation, etc.

[0003] When the prior art is used, a pole is installed at the bottom of the reservoir, and the buoyancy of the water is used to move the float box. When the water level rises, the float box rises, thereby triggering a switch to alarm the staff.
