Deckma Omd11 Manual 'link' -

The OMD-11 utilizes advanced optical technology to deliver real-time contamination data.

Often caused by dirty water, air bubbles, or a dirty measuring cell. 8. Summary of Components The OMD-11 system consists of four main components: Measuring Cell: The core sensor that detects oil content. Data Processing Unit: Analyzes the signals from the sensor. Power Supply Box: Provides power to the unit.

: Run standard marine-grade piping from the separator line into the instrument's Sample Conditioning Unit (SCU) . Ensure the outlet flows freely by gravity back to the bilge or a designated drain tank.

The OMD-11 is part of a broader family of DECKMA oil-in-water monitors, which includes newer models like the OMD-21, OMD-24, OMD-2005, and OMD-2008. The OMD-11 was developed from DECKMA's extensive experience, following earlier models like the OCD series and the OMD-7, which was the first to distinguish between oil, solids, and turbidity. It is important to note that as of this writing, the DECKMA OMD-11 is an older unit that is no longer in production. However, spare parts and support remain available. deckma omd11 manual

Wait for the instrument initialization phase to complete (usually a few seconds). Read the current oil content on the digital display. Fresh Water Zeroing (The Clean Water Test)

: The unit is designed to meet International Maritime Organization (IMO) resolution standards. Advanced Solids Suppression : A standout feature of the

The unit has potential-free 1-pole changeover contacts (3 A / 24 V) for controlling external alarms and valves. 4-20 mA Output: Used for data logging or remote monitoring. 5. Operating Instructions The OMD-11 is designed to be user-friendly. The OMD-11 utilizes advanced optical technology to deliver

Understanding the technical limits of the OMD-11 ensures safe operation and prevents system damage. 0 to 30 ppm (parts per million). Accuracy: Meets IMO Resolution MEPC.60(33) standards. Linearity: Better than ±2 ppm. Display: Seven-segment LED display.

The sensor cell must be placed in a way that minimizes air bubbles in the sample. 4. Wiring and Electrical Connections Summary of Components The OMD-11 system consists of

Without this appendix, you cannot perform remote testing from the wheelhouse.

Oil droplets suspended in the water scatter the light beam.

Given that the OMD-11 is an older unit, eventual component failure is inevitable. The manual's final sections include lists of recommended onboard spare parts and addresses for getting support.

Features a 0/4 - 20 mA signal for remote monitoring and two adjustable alarm relays. 2. Operating Principle: Light Scattering
