DECKMA HAMBURG GmbH is a well established company, supplying Oil-in-Water Monitors and Systems to the marine and industrial markets since the early 1970’s. The Managing Director, Mr. Günther Schulze, founded the company as a representation office in Germany for companies like Bailey Meters, Metritape, Tanksystem and Bristol Babcock Ltd. DECKMA HAMBURG GmbH has been involved in sales, service, engineering and development of 15 ppm Bilge Alarm Monitors and Tanker Deballasting Systems from the beginning of the MARPOL regulation 73/78 for pollution prevention equipment on board of ships.
Since the early 1980’s DECKMA HAMBURG GmbH introduced the wellknown OCD-Series of 15 ppm Bilge Alarm Monitors. More than 13.500 OCD-Bilge Alarm Monitors have been sold under the name DECKMA HAMBURG GmbH, mainly to Separator Manufacturers. In the industrial field, DECKMA HAMBURG GmbH developed “Turnkey Monitoring Systems” for the control of waste water in a variety of applications.
Demands for better measuring technique required a complete new development. In 1996 DECKMA HAMBURG GmbH launched an all new Oil-in-Water Monitor, the “OMD-7 Industrial Monitor” capable of distinguishing between the different characteristics of Oil particles, Solids particles and Water Turbidity on a continuous basis. This was the beginning of a complete new Series of Oil-in-Water Monitors – the OMD-Series. The latest version of 15ppm Bilge Alarms “OMD-24 / OMD-2008” has been launched in the market by the second half of 2012. This unit meets the latest IMO Resolution MEPC. 107(49)
Nowadays, DECKMA HAMBURG GmbH is a flexible and innovative enterprise with own Research- and Development Department, Sales and Marketing, Service and Engineering as well as manufacturing facilities for Monitors and Systems. Personal involvement of the Managing Director, the Directors and Employees are the strength of the company. A new factory located in Hamburg with 1000 m² floor space was opened in 2001 to cope with the continued business expansion,especially for the Bilge Alarm Monitor Sector.
Deckma Hamburg GmbH is the market leader of 15ppm Bilge Alarms. Up to now more than 45.000 OMD Bilge Alarms have been supplied mainly to Oily Water Separator Manufacturers worldwide.
Based on more than 45 years experience in continuous Oil-in-Water Monitoring we have gained recognition of this field world-wide. Our aim is to continue with outstanding quality of our products and customer orientated services world-wide.
OMD-2008 EV FC MCU with Flow Control Deckma
The OMD-2008 EV FC MCU is equipped with a Flow Sensor. The Flow Sensor is positioned in the Drain line of the Measuring Cell.
If the flow rate through the Measuring Cell is too low, or if the sample is not flowing at all, the Instrument will go to Alarm condition and issue a “Status: Flow?” message. According to MEPC.107(49) the 15ppm Bilge Alarm has to be provided with a representative sample, i.e. the operator of the instrument is responsible to maintain a proper sample flow through the instrument.
The recommended sample flow rate for Deckma instruments is approx. 2 Liters per Minute. At this flow rate, with a common setup of separator and 15ppm Bilge Alarm, it is easily possible to reliably operate the instrument, and to ensure the required short reaction time to changes in the oil content of the effluent water.
The instrument does not know about the sample stream flow rate. If circumstances lead to interruptions of the sample flow, or if the sample flow is stopped completely, the portion of the sample that is in the sample glass tube will be measured continuously. The instrument will display the same measurement result for a long time, but it may fail to adequately react to changes in the overboard discharge water oil content.
For many years the OMD series instruments have had a dedicated input to connect a flow switch to monitor the sample flow rate. However, not many installation have been made with an additional flow switch. A more easy solution had to be found, a solution that does not require additional pipework, or electrical work, on site. The new OMD-2008 EV FC MCU version of the OMD-2008 instrument come with a flow sensor that measures the sample flow rate, and automatically sets the instrument into alarm condition, if a sufficient flow rate is not maintained.
Constructed to make accidental flow interruptions, incorrectly closed valves, and a missing sample stream harmless events that do not lead to unlawful discharge, the OMD-2008 EV FC MCU also makes manipulation and tinkering with the instrument setup much less rewarding. Additionally for the OMD-2008 EV FC MCU instruments a Manual Cleaning Unit (MCU) is available. This system allows to quickly clean the sample glass tube without having to open the Measuring Cell. With the MCU maintenance of the system becomes very easy, ensuring high reliability and reduced maintenance workload.
