How to measure the relative water level changes of rivers and lakes in uninhabited areas is one of the difficulties in this technical field. Conventional methods require human intervention, which brings difficulty to its implementation. The utility model adopts an ingenious method to solve this problem.

The utility model uses helicopters or boats to put the monitoring system into the lake, and the underwater device 3 will sink into any position on the bottom of the water. The pressure sensor 22 is fixed on the top of the anchor, which is equivalent to providing a pressure measurement reference. Since the multifunctional mooring cable 2 is longer than the depth of the deepest lake, the floating ball 1 then emerges from the water surface, and the water surface pressure sensor 21 It is set at the bottom of the floating ball, that is, at a fixed position of 0.5m-2m underwater, and rises or falls with the fluctuation of the water in rivers and lakes.
