ALEAN’s 3 beams detector is the latest used on the ferryboat in the Qiongzhou Strait. The Qiongzhou Strait is located between Guangdong and Hainan provinces. The ferry goes back and forth at sea every day, and puts forward high requirements on the detector’s resistance to harsh environments. During the construction of the project The installer has fully sealed the detector, including blocking the outlet hole with glass glue for resisting salt water and air. The current users of the project are very satisfied, and we will also share more product use cases.
