[0002] The drum filter of the nuclear power plant's nuclear island safety plant water system and the conventional island seawater circulating water system uses a water level gauge with a sleeve to monitor the filter pressure difference. When the seawater sediment content is high, the water level gauge often gets stuck due to sediment accumulation, causing the water level gauge to fail and affecting the drum filter pressure difference monitoring.
