The Deckma OMD-11 is a high-precision 15 ppm bilge alarm monitor designed to improve the reliability and operation of oily water separator (OWS) systems. Meeting the requirements of IMO Resolution MEPC.60(33) , the OMD-11 utilizes advanced solids suppression technology to distinguish between oil particles, solid particles, and water turbidity.
The measuring cell should be cleaned periodically to remove oil deposits.
Connect the power supply to terminals 1 and 2, ensuring the voltage matches the rating plate on your specific unit.
The tapping should be on a vertical section of the discharge line to prevent air bubbles from interfering with the optical sensor. Operation & Calibration

Data compiled from
Turn on the power. The unit will undergo a self-check and briefly display the software version.
Ensure the sample water pressure is within the manual’s specified limits (typically 0.1 to 10 bar) to maintain a steady flow. 4. Calibration and Maintenance Regular maintenance is vital for MARPOL compliance.
The printed manual lacks decision trees. Technicians often create their own to diagnose flow blockages or sensor drift.
Replacing electronic components (except fuses) typically requires re-calibration to avoid inaccurate readings. Troubleshooting Indicators
The sample cell should be regularly cleaned using fresh water to prevent fouling from oil residues.
Check that the display is functional and that the sample flow is consistent.
The Deckma OMD-11 is housed in a rugged, splash-proof enclosure containing the electronic processing unit and the physical measuring cell. System Breakdown
