Effective bilge water management is essential for maintaining marine environmental compliance and preventing the discharge of excessive oil content into the sea. The OMD-24 Series Bilge Alarm Unit is designed specifically for integration with 15 ppm oily water separator systems, providing accurate oil-content monitoring and reliable alarm protection for shipboard applications.
Engineered to meet and exceed the requirements of IMO Resolution MEPC.107(49), the OMD-24 combines accurate measurement, adjustable alarm settings, malfunction indication, and optional data logging capabilities in a compact marine-grade system.
In today’s marine industry, environmental compliance is not optional — it is critical. The OMD-24 Series Bilge Alarm Unit is a trusted marine monitoring solution designed to deliver highly accurate oil content detection for oily water separator systems onboard ships.
The OMD-24 Bilge Alarm continuously monitors the oil concentration of water discharged from an oily water separator. If the measured oil content reaches the configured alarm threshold, the system provides a visible alarm and activates the corresponding relay outputs.
With a measurement range of 0–30 ppm and an IMO monitoring range of 0–15 ppm, the OMD-24 offers dependable monitoring for vessels where accurate oil-content detection and environmental protection are critical
Reliable Bilge Monitoring. Faster Alarm Response. Stronger Environmental Protection.
Key Features of the OMD-24 Bilge Alarm
Adjustable 15 PPM Alarm Settings
The OMD-24 is supplied with two factory-adjusted 15 ppm alarms. Alarm thresholds can be adjusted between 1 ppm and 15 ppm, allowing the system to be configured according to operational requirements.
High-Accuracy Oil Content Monitoring
The system is designed to provide measurement performance exceeding the requirements of IMO MEPC.107(49), supporting reliable monitoring of oily water separator discharge.
Fast Alarm Response
The OMD-24 provides rapid alarm response to help operators identify excessive oil concentration and take corrective action quickly.
Dual Independent Alarm Relays
Two independently adjustable alarm contacts provide flexible control and alarm functionality for shipboard oily water separator systems.
Built-In Malfunction Indication
The front-panel SYS LED provides an immediate indication of system status. A change from normal green indication to solid red alerts operators to a malfunction.
Optional 0/4–20 mA Output
An optional analog output enables connection to external recorders, meters, and vessel monitoring or automation systems.
IP65 Marine Protection
The IP65 enclosure provides protection against dust and water ingress, making the OMD-24 suitable for demanding marine and engine-room environments.
