: The OMD-11 is specifically engineered to reduce sensitivity to solids like iron oxide, ensuring fewer false alarms compared to older models. Important Maintenance Notes
The manual provides a clear, step-by-step standard operating procedure (SOP) for bringing the OMD-11 online. deckma omd11 manual
To fully appreciate the OMD-11 manual, one must understand its evolution. The predecessor, the OMD-2, was a purely pneumatic system using a rotating disc and measuring tube. While effective, it was prone to clogging and mechanical wear.

A primary engineering benefit of the OMD-11 is its advanced . Older bilge monitors often misidentified solid contaminants—such as rust particles, mud, or iron oxide—as oil, leading to false alarms. The OMD-11 significantly mitigates this background sensitivity. For example, a concentration of 15 mg/L of black iron oxide registers as a severe 15 ppm oil violation on older systems, but displays as a negligible 2 ppm on the OMD-11. Alarm Integration and Failsafe Logic
Use a pressure-regulating valve if sample pressure exceeds 2 bar. Electrical Wiring Isolate the main power before opening the enclosure. Wire the power supply to the designated terminals.
Regular, professional calibration is necessary to maintain IMO compliance. 3.2 Setting Alarms features two independent oil alarm circuits. Try again later
Run clean, oil-free water through the cell until the reading stabilizes.
Features a sample glass tube through which the bilge water flows. It contains infrared transmitters and receivers.
Crew members can perform a function test using specialized validation kits or by checking zero-points with certified clean water. Always log maintenance and calibration swaps in the Oil Record Book.
