The IMO MEPC107(49) Standard Marine bilge water alarm device has been designed specifically for use in continuous monitoring of oil-in-bilge water, 15 ppm alarm and control of discharge, detection, memory and enquiry of alarm status. It is applicable to detect boiler condensate water. And it applies to oil and chemical industries as well.
The IMO MEPC107(49) Standard Marine bilge water alarm device use the technology of near infrared measurement, which can display the detected result in real time. The unit is supplied with 2 works-adjusted alarms. The set point (15ppm factory set) could be adjusted at any moment through the panel. If an alarm set point is exceed, the alarms are visible at the front panel and the appropriate relays are switched, that can be achieved the movement control of overrun closedown or the treatment of overrun recycle, and the memory and enquiry of alarm record. Furthermore, a 4 - 20
mA (equal to 0 - 15ppm) effective signal output is available for driving a recorder or external meter.
The certificate of type approval test has been obtained through comprehensive tests. This device is in accordance with the IMO-Resolution MEPC.107 (49)
Several optical sensors measures a combination of light scattered and absorbed by oil droplets in the sample stream. The sensor signals are then processed by a microprocessor to produce linearised output. If an alarm occurs, the two oil alarm relays are activated after the adjusted time delay. And it stores up the actual time, display value, alarm output status and alarm control feedback status. By front face menu operation, the memorized information can be enquired anytime. The microprocessor continuously monitors the condition of the sensor components and associated electronics to ensure that calibration accuracy is maintained over time and extremes of environmental conditions.
Features

Works adjustment
Easy zero adjustment via push buttons (+-5ppm)
Adjustment
The unit is delivered with a works adjustment according the manual. The alarm points are set to 15ppm.
The "Zero" point is also works adjusted and can be re-adjusted on site by using clean water and the push button
"offset" at the front panel
3.3 Displays and Alarms
In the unit are two independent alarm circuits available. Both can be set separately set from 1 to 15 ppm. The set
points can be changed according to the requirements on site. An alarm point setting above 15ppm is not possible.
The adjustment can be done in the programming mode as described in Section 10.4.
In this mode also the individual adjustment of the time delays for the alarms output can be done.
Both alarm circuits are also connected with an alarm LED on the front panel. Additional to the alarm LED's each
alarm circuit is equipped with a relay with potential free alarm contacts. These contacts can be used for external
processing of the signal or for control of further functions.
If a malfunction or failure of the power supply occurs, both relays will switch to alarm condition.
