Bilge water level alarm

A bilge water level alarm is a device that detects and alerts when the bilge water level reaches a certain predetermined threshold. It can be used to warn a ship's crew when the bilge water level begins to rise or fall abnormally, which can be dangerous for the ship's stability and safety. Water level alarms can be activated manually or automatically according to predefined level parameters, and can be configured to send notifications to the crew or trigger activation of the bilge pump to evacuate bilge water.
