How does a 15 ppm alarm work?
How does a 15 ppm alarm work?
A 15ppm Bilge Alarm is normally used in connection to a ship’s oil filtering equipment (also known as “bilge water separator”), monitoring the oil content of the separated/filtered water and stopping the discharge into the sea if the oil content exceeds 15ppm (parts per million).
What is ppm in ship?
1. An Oil content meter: The oil content meter is used to analyze the content of oil in the water that is to be discharged overboard. This oil is expressed in parts per million (PPM).
How often must the accuracy of a 15 ppm bilge monitor be checked?
five years
The accuracy of 15 ppm bilge alarms is to be checked by calibration and testing of the equipment conducted by a manufacturer or persons authorized by the manufacturer and should be done at intervals not exceeding five years after its commissioning, or within the term specified in the manufacturer’s instructions.
Who should check and certify the accuracy of a 15 ppm bilge monitor?
The accuracy of 15 ppm bilge alarms is to be checked through the calibration and testing of the equipment, to be conducted by the manufacturer or by persons authorised by the manufacturer.
How do you test a 15 ppm alarm?
Check lamps 11, 17, 18 turned off and lamp 13 lighting up. Hold the OIL ALARM switch 33 pressed. OIL ALARM is issued in 2 seconds. OIL ALARM lamp 17 blinks and 15 PPM is displayed.
What would be the result if the 15 ppm bilge alarm monitor activates during operation of the OWS?
If the oil content is less than 15 ppm, the OCM allows the water to be discharged overboard. If the oil content is higher than 15 ppm, the OCM will activate an alarm and move a three-way valve that, within a short period of time, will recirculate the overboard discharge water to a tank on the OWS suction side.
What is the meaning of 15 ppm by mass?
1) 15 ppm means 15 parts in 1 millions (10^6) and percentage always for 100. hence 15 ppm = (15/10^6 )*100. = 15*10^-4.
What is the meaning of 15 ppm in chemistry?
1) 15 ppm means 15 parts in 1 millions (10^6) and percentage always for 100. hence 15 ppm = (15/10^6 )*100. = 15*10^-4. = 1.5*10^-3.
What is bilge alarm 15 ppm?
