Ships for bulk transportation of bulk dry bulk goods such as grains, coal, ore, salt, cement and the like. The whole cargo hold area of the bulk carrier is provided with large ballast tanks from bow to stern to adjust the navigation draft state of the ship in a matching way. The ballast tank of the large bulk carrier is divided into a top-side ballast tank and a bottom-side ballast tank. Because ocean cargo vessels have a long voyage time and need to be equipped with a large fuel tank to load fuel for fuel supply, a top ballast tank near the tail end is usually selected as the fuel loading tank for the convenience of pipeline laying. The loading capacity of the cabin is measured by adopting two modes of a liquid level remote measuring system and a depth measuring pipe at present, the liquid level remote measuring system is provided with an induction signal in the cabin, the signal is transmitted to a computer terminal through an electric signal, and generally, the loading number of the cabin can only be roughly judged, and the accurate measurement cannot be carried out.
