Calibration of Oil Content Monitors

Calibration of Oil Content Monitors


Calibration of oil content monitors is crucial for ensuring accurate measurements and compliance with environmental regulations. These monitors are used to detect the concentration of oil in water, particularly in marine environments, to prevent illegal discharges and protect marine life.
Key Points:
Regulatory Compliance: Regular calibration is mandated under MARPOL (International Convention for the Prevention of Pollution from Ships) guidelines. The accuracy of 15 ppm bilge alarms must be checked by calibration and testing, typically every five years or as specified by the manufacturer1.
Types of Monitors: There are different types of oil content monitors, including light-scattering and fluorescence detection technologies. Light-scattering monitors measure the cloudiness of water, while fluorescence detection monitors identify oil by its unique light emission properties2.
Calibration Process: Calibration involves adjusting the monitor to ensure it provides accurate readings. This can be done by the manufacturer or authorized personnel. Some systems allow for the replacement of the measuring cell to maintain certification without taking the monitor out of operation
