To provide a liquid level measuring device which has a relatively simple structure, and can accurately measure a liquid level while saving power.SOLUTION: A liquid level measuring device, which measures the liquid level of a predetermined liquid, comprises: an optical sensor that measures the distance to a measurement target by converting the time until projected laser light returns to a light receiving element into a distance; a communication unit that wirelessly communicates signals between the optical sensor and a predetermined server; a measurement pipe which is opaque and hollow, one end of which is sealed, and the other end of which is opened; a float inside which a magnet is arranged, into the inner diameter side of which the measurement pipe is inserted, and which moves up and down along the outer peripheral surface of the measurement pipe; a probe that has a probe side magnet moving in pairs with the float side magnet, and that slides up and down along the inner peripheral surface of the measurement pipe by the motion of the probe side magnet; and a sensor case that is attached to an opening end of the measuring pipe so as to block the opening end of the measuring pipe.SELECTED DRAWING: Figure 1 【課題】比較的簡単な構造で、省電力ながら正確に液位を計測可能な液位計測装置を提供。【解決手段】本開示の液位計測装置は、所定の液体の液位を計測する装置である。液位計測装置は、投光したレーザー光が受光素子に戻ってくるまでの時間を距離に換算することで測定対象までの距離を計測する光センサと、光センサと所定のサーバとの間の信号を無線で通信する通信部と、内部が中空に形成された不透明なパイプであって、一方の端部が密閉され他方の端部が開口された測定パイプと、その内部に磁石が配置され内径側に測定パイプが挿入されることで該測定パイプの外周面に沿って上下に移動するフロートと、フロート側磁石と対になって運動する測定子側磁石を有し該測定子側磁石の運動によって測定パイプの内周面に沿って上下に摺動する測定子と、測定パイプの開口端を遮光するように該測定パイプの開口端に装着されるセンサケースと、を備える。【選択図】図１
