The OMD-11 features 14-segment LEDs and simple push-button controls for on-site adjustments. OMD-11 Oil-in-Water Monitor Manual | PDF | Relay - Scribd
is its ability to distinguish between actual oil particles and solids or water turbidity. This significantly reduces false alarms caused by non-oil contaminants like black iron oxide.
Use a rigid vertical surface. Ensure enough clearance on all sides for maintenance.
is designed for use in conjunction with 15 ppm oily-water separator units. It provides continuous monitoring, ensuring that any discharge exceeds 15 ppm results in an alarm and the automatic activation of the overboard valve to stop discharge. Key Features 0-30 ppm. deckma omd11 manual
Two independent potential-free changeover relays. 2. Principle of Operation
: If you're unable to find the manual through online searches, you can try contacting Deckma directly or reaching out to a marine equipment supplier and requesting a copy of the manual for the OMD11.
If the monitor consistently shows high readings, the sample cell may require cleaning to remove oil residues. The OMD-11 features 14-segment LEDs and simple push-button
The unit should be mounted on a vertical bulkhead away from excessive vibration and heat. Piping: Sample Inlet: R 1/4" Female connection. Sample Outlet: Connected to a drain line.
: The entire unit must be sent to an authorized Deckma service center for formal calibration and stamping.

How the Deckma OMD-11 Works Use a rigid vertical surface
Avoid random PDF download sites. Many "free" Deckma OMD11 manuals are for obsolete revisions (pre-2015) that list incorrect Modbus addresses, leading to control system integration failures.
The Deckma OMD-11 Oil Content Monitor (OCM) is a critical piece of marine equipment designed to prevent ocean pollution. It continuously measures the oil concentration in bilge water before discharge.
