The Rivertrace Smart Bilge Alarm is a state-of-the-art oil-in-water monitor designed for marine bilge applications. It ensures compliance with the International Maritime Organization (IMO) resolution MEPC.107(49) for bilge water discharge. The system utilizes Rivertrace’s advanced “Smart Cell” technology, which employs a nephelometric (light scattering) principle to provide highly accurate and reliable measurements of oil content. This innovative design eliminates the need for manual cell cleaning, significantly reducing maintenance requirements and preventing issues related to fouling. The Smart Bilge Alarm provides continuous monitoring, ensuring that any overboard discharge is within the legally permissible limits, typically 15 ppm.
