To provide a water level measuring device with which it is possible to measure a water level with high accuracy ranging from a low water level position where the water level is low to a high water level position where the water level at which a sensor is submerged is high.SOLUTION: A water level measuring device 20 comprises: a first water level sensor 30, provided on the reverse side 10a of a manhole cover 10, for transmitting a supply signal in a prescribed irradiation range D and detecting a water level when the water surface is in a first water level range A; and a second water level sensor 40 of float type that detects a water level when the water surface is in a second water level range C, with a float 42 arranged so that when the water surface is in the first water level range A, it is located in the prescribed irradiation range D of the supply signal transmitted by the first water level sensor 30. The water level measuring device 20 includes a water level calculation unit 50 which, when the water surface is in the first water level range A, calculates the water level of water surface excluding a detection component reflected at the surface of the float 42 from the reflection signal received by the first water level sensor 30.SELECTED DRAWING: Figure 1
【課題】水位が低い低水位位置からセンサが水没する水位が高い高水位位置まで精度よく水位の測定が可能な水位計測装置を提供する。【解決手段】水位計測装置２０は、マンホール蓋１０の裏面１０ａに設けられ、供給信号を所定の照射範囲Ｄで送信するとともに、水面が第一水位範囲Ａに位置する場合に水位を検出する非接触式の第一水位センサ３０と、水面が第二水位範囲Ｃに位置する場合に水位を検出するフロート式の第二水位センサ４０と、を備える。そして、フロート４２は、水位が第一水位範囲Ａに位置する場合に、第一水位センサ３０が送信する供給信号の所定の照射範囲Ｄ内に位置するよう配置され、水位計測装置２０は、水位が第一水位範囲Ａに位置する場合に、第一水位センサ３０が受信した反射信号からフロート４２の表面で反射した検出成分を除外して水面の水位を算出する水位算出部５０を備える。【選択図】図１
