Apparatus for measuring the level of water in an enclosure. It comprises an assembly, which is constituted by a radiation source located in the vicinity of the enclosure wall, and n radiation detectors separated from the radiation source by a path traversing the enclosure and located at different levels on a same vertical line. After amplification, each detector supplies a signal proportional to the intensity of the radiation received. It comprises means for processing the signals supplied by the detectors, said means being constituted by n-1 dividing circuits, the detectors being connected in pairs to a dividing circuit, which forms the quotient mu 1/ mu i+1, the level then being located in the gap between the detectors, for which the quotient mu i/ mu i+1 is maximum. |
