Oil Content Monitor
USCG Approved
Meets IMO MEPC 60 (33) Regs
 The OCD CM is the result of market research and development of new technologies to produce a monitor that exceeds the existing standards and meets the requirements requested by customers and operators worldwide.
The OCD CM has been specifically designed to eliminate the effects that cause false instrument alarms where the water contains high levels of solid particulates. In particular the unit has been designed to ignore the presence of iron oxide, of which most bilges have a plentiful supply, and output only the true oil concentration.
 This is achieved by using a multiple sensor measuring cell combined with advanced electronics and mathematical formulae. The graph below shows the dramatic difference between the OCD CM and its predecessor, the OCD 2M.
All this in a package that is 25% the size of the OCD 2M. The OCD CM also has built in diagnostic features and the ability to show the inspectors if the software has been tampered with. Additionally the unit runs through a self check diagnostic routine on power-up that ensures all parameters are within limits and activates the alarm relays at their prescribed set points. All user adjustable parameters are accessed from an easy to use pushbutton menu from the front of the unit.
The OCD CM incorporates superior performance with low cost and exceeds the requirements of Resolution A393 (X) and MEPC 60(33). It is the basis of a new range of products and is available with the following options:
Manual Clean device for manual cell cleaning procedures
Automatic cell clean device for automated cell cleaning
Fully Automated Bilge Water Monitoring system to remove the Human element from the process
Chart Recorders to record the output — contact RTE for more details
Verification Kits to demonstrate the unit’s calibration is in tolerance to port state inspectors — contact RTE for more details
Spares parts and service support to maintain your unit in a first class condition — contact RTE for more details
Key features include:
- Greatly Enhanced Solids discrimination over the IMO requirements
- Simple operation
- Customer changeable parameters easily accessed from front panel
- External cell to keep water away from electronic parts
- Alarms adjustable from 1-15 ppm
- 2 Oil alarms and a separate fault alarm
- 0-20mA, 4-20mA, 0-5 V and 1-5 V outputs available as standard
- 24v AC or 110/220 v AC available — no separate power supplies required
- 75% weight reduction over the OCD2M — lower costs
- Type approved The OCD CM will be available for deliveries from the end of June 2000
