Replacement Options for 15ppm Bilge Alarm/Monitor
For replacing a 15ppm bilge alarm/monitor, top-quality brands include:
These models are designed for easy installation and onboard cell replacement, ensuring full compliance with IMO regulations.
IMO Regulations on Bilge Water Discharge
The International Maritime Organization (IMO) mandates that bilge water discharged into the ocean must contain less than 15 parts per million (15ppm) of oil to prevent marine pollution.
Function of a 15ppm Bilge Alarm/Monitor
Installed alongside Oily Water Separators (OWS), these monitors continuously track oil content in the discharged water. If the oil concentration exceeds 15ppm, the system automatically stops the discharge to prevent non-compliance.
Key Features for Replacement
Onboard Cell Replacement – All leading brands provide easy replacement of the measuring cell, either with a pre-calibrated unit or through calibration check kits.
Compact Design – These monitors are space-efficient and designed for seamless integration with both new and existing Oily Water Separators (OWS).
Ease of Installation – Designed for quick and simple installation by the ship’s crew, typically requiring less than an hour.
Type Approval – All models are IMO type-approved, ensuring compliance with international maritime regulations.
BilgMon 488 Versions, Compatibility & Replacement Guide
BilgMon 488 Versions, Compatibility & Replacement Guide
It is important to understand that BilgMon 488 is available in both standard and special versions, and selecting the correct replacement part depends on the serial numbers of the existing master unit and sensor unit. Using the correct version ensures proper compatibility, reliable operation, and smooth onboard installation
Why Checking BilgMon 488 Version Is Important
Before replacing a BilgMon 488 Master Unit, Sensor Unit (Measuring Cell), or the complete BilgMon 488 equipment, you should always verify the serial numbers of the existing units.
Some BilgMon 488 systems were manufactured as special versions for specific oily water separator manufacturers, and these versions may require matching replacement components. Choosing the wrong version may lead to compatibility issues, installation problems, or operational errors.

Replacement Guide for BilgMon 488
Replacing Only the Master Unit or Sensor Unit
If the existing BilgMon 488 is a special HSN version with:
- Master unit serial number starting with EDA
- Sensor unit serial number starting with EDB
and you want to replace only one part — either the master unit or the sensor unit — then you must use the same special HSN version replacement part.
This is essential to maintain system compatibility and correct operation onboard.
Replacing the Complete BilgMon 488 Equipment
If you are replacing both the master unit and sensor unit together, then the new BilgMon 488 can be supplied as a standard version.
Available standard replacement options include:
- 24V AC/DC model
- 115/230V AC model
This provides more flexibility and makes future maintenance easier.
