Oil Cotent Meters For Oily Water Separator
-Introduction]
The OCM-07 type oil-in- water monitor has been designed specifically for use in continuous monitoring of oil-in-condensate or oil-in-boiler feed water without specific environment condition, it is applicable to high water temperature.
The unit is supplied with 2 works-adjusted alarms. The set point (15mg/l) could be adjusted at any moment through the front panel. If an alarm set point is exceed, the alarms are visible at the front panel and the appropriate relays are switched.
Furthermore a 0(4) - 20 mA (equal to 1 30 ppm) signal output is available for driving a recorder or external meter.
1.2 This device is type approved by Q/YNK01-2009 < OCM-series Oil-in-Water Monitor Device Technical Specification>, and it is in accordance with the IMO-Resolution MEPC. 107 (49).
-Measuring Principle
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. 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.
