Claims (1)
設置されたプリズムと、このプリズムに高さ方向に均一
な光を入射させる光源と、上記プリズムに入射された光
の反射光を検出する光電変換素子とを備え、被測定液の
有無により反射光が′ 変化し光電変換素子を流れる電
流が変化することを利用して貯留槽内の液位を検出する
ことを特徴とする液位検出装置。A prism installed extending in the height direction in a storage tank in which the liquid to be measured is stored, a light source that makes uniform light incident on the prism in the height direction, and reflected light of the light incident on the prism. The liquid level in the storage tank is detected by utilizing the fact that the reflected light changes depending on the presence or absence of the liquid to be measured, and the current flowing through the photoelectric conversion element changes. Liquid level detection device.
