In the maritime industry, environmental compliance and operational safety are of utmost importance. One critical component of ensuring both is the proper monitoring of bilge water discharge. The Brannstrom BilgMon 488 is a state-of-the-art bilge alarm system that plays a vital role in helping ships comply with international maritime regulations, particularly those concerning the discharge of oily water.

What is the Brannstrom BilgMon 488?

The Brannstrom BilgMon 488 is a highly reliable 15 ppm bilge alarm designed in accordance with IMO Resolution MEPC.107(49). It is used to monitor the oil content in bilge water before it is discharged overboard, ensuring that only water with acceptable levels of oil contamination is released into the sea. It is also available in a 5 ppm version to meet stricter class requirements such as Clean Design notation.

Key Features of the BilgMon 488

1. Wireless Measuring Cell
One of the standout features of the BilgMon 488 is its wireless, detachable measuring cell. This smart cell communicates with the main unit wirelessly and can be easily removed and replaced when recalibration is needed. This simplifies maintenance and reduces downtime significantly.

2. Automatic Fresh Water Flushing
To maintain sensor accuracy and cleanliness, the system is equipped with an automatic freshwater flushing function. This feature helps in minimizing the buildup of contaminants that could affect readings.

3. User-Friendly Operation
The device includes a clear LCD display and keypad for easy interaction. Users can retrieve historical data and perform settings adjustments either directly from the display or via a USB connection.

4. Reliable Alarming System
The BilgMon 488 offers two programmable alarm levels. These alarms trigger when the oil content exceeds the set thresholds, typically between 1 and 15 ppm. Alarm indicators include relays and LED lights, and an analog current output (0/4–20 mA) is available for integration with ship control systems.
