Theory

In marine operations, the quality of delivered fuel can have a direct impact on engine health, maintenance costs, and compliance with international regulations. This makes fuel sampling not just a routine task, but a critical quality assurance measure.

In industries where fuel quality affects equipment performance, having an easy and accurate way to verify viscosity is essential. From fuel supply depots to power plants and processing sites, engineers and operators increasingly need on-the-spot verification tools that don’t rely on sending samples to laboratories.

The BilgMon 488 is one of the most widely used 15 ppm bilge alarm monitors in the marine industry. Built for reliability, compliance, and ease of maintenance, the system is engineered to ensure accurate monitoring of oil-in-water content in bilge discharges. Its construction consists of two compact but highly specialised components: the MASTER unit and the SENSOR unit, each designed to perform specific roles within the monitoring system.

Maintaining compliance with MARPOL and IMO requirements is essential for any vessel operating an oily water separator (OWS). The BilgMon 488 is designed to help shipowners, operators, and service engineers meet these requirements through intelligent alarm handling, integrated monitoring functions, and reliable logging of bilge water discharge events.

Flow verification plays an increasingly critical role in bilge water monitoring, particularly as environmental regulations tighten and Port State Control inspections become more rigorous. The BilgMon 488 Flow Switch, designed exclusively for use with BilgMon 488 Version 5, provides a new level of operational assurance by ensuring that the bilge alarm only analyses valid sample flow.

The BilgMon 488 Version 5 is now officially launched, marking a major step forward in bilge water monitoring technology. Building on the strong foundation of Version 4, the new Version 5 introduces powerful upgrades in precision, flexibility, and operational reliability - making it the most advanced 15 ppm bilge alarm system available today.

We are proud to introduce the new Flow Switch for BilgMon 488, designed to work exclusively with the latest BilgMon 488 Version 5. This innovative accessory provides real-time flow verification to ensure that the bilge alarm only analyses valid bilge water samples - significantly reducing the risk of non-compliant discharges.
