Bilge Alarm

Bilge Alarm is a device that controls separator/filter unit that executes the discharging of bilge.

It gives warning signal when the concentration of the discharged bilge water is higher or equal to 15ppm.

It is separated into 2 units, control box and sensing unit, so that the installation and maintenance is easier. It acquired KR and Ministry of Maritime Affairs & Fisheries standards by being satisfied with regulations of IMO MEPC60(33) in 1997. (ISO9002 Certificate, CE Mark-DNV)

▶ Detail Information

Bilge alarm indicates an alarm signal when the concentration of drainage from Oily Water Separator/Filter Unit is higher or equal to 15ppm. As the solenoid valve will automatically shut off for 20 seconds after the response, so discharging process of bilge water could be operated without any attention of operator.

▶ Structure

The bilge alarm case is constructed as a steel box in accordance with IP56 and sensing unit is sealed for water-proved. Electric parts and warning circuit are located in the main board. The front side of bilge alarm has digital ppm displayer and 2 LED (Normal : green, Alarm : red). Sensing unit and case is connected with flexible cable to avoid any damages.

▶ Principle of measurement

The oil-contents in bilge water is measured by scattering action of the light induced by oil particles. By measuring scattering light and calculating the scattering rate, it factors in the influences of varying light sources. Scattering light can be detected by exposing the high intensity infrared rays to the sampling water passing through the cylindrical Sample -Tube(cell).
