Cheap 15ppm Bilge Alarm Oil Cotent Meters for Water Treatment Equipment
1. INTRODUCTION
The OCM-15 15PPM 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 OCM-15 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 OCM-15 type approval test has been obtained through comprehensive tests.
This device is in accordance with the IMO-Resolution MEPC. 107 (49).
