Control cabinet: Share the same type with the cabinet of the usual alarm system.
Control cabinet of water alarm system penetrates the cargo tunnel
Water sensors penetrate the cargo tunnel: As a pressure sensor, it is possible to use a 2-level alarm sensor and the main alarm, minimizing wire pulling and construction work. Ip68 immersion and explosion level sensors are essentially safe (highest level)
Water alarm sensor into the explosion-style cargo bunker
Water sensor into the nasal drum compartments: As a 1-level float sensor with a protective tube, the sensor is installed in the pits on the nasal drum compartments, this sensor also reaches the level of explosion prevention is safe in nature and ip68 immersion.
