Bilge water quality monitoring

By utilising the “Smart Cell” Detector Array Technology, developed by Rivertrace, the OCM analyses all three oil types (HFO, Diesel and Emulsions) simultaneously without the need for re-calibration.

A manual cell cleaning device is included as standard to easily enable routine maintenance. Optical cell fouling is recognised as a leading cause of monitor malfunction or incorrect reading. By simple operation of the manual cleaning device, the “Smart Cell” remains in optimum operating condition.


Replacement calibrated measuring cells can be purchased for easy change over on board the vessel and calibration check kits enable the crew to demonstrate the monitor is within factory calibration to PSC Surveyors.

The Smart Cell Bilge Alarm is readily available as a 5ppm version if required. It can also be tailor made for Hazardous Environments (Zone 1 & 2) as an Exd system with Auto Clean, all enclosed in an explosion proof cabinet.

All options can be ordered from new or retrofitted to existing Rivertrace Smart Bilge monitors.

The flowswitch option has been designed to ensure that bilge water is flowing through the measuring cell when in monitoring mode. An error is shown on the display if there is no flow.


The autoclean option has been designed to ensure that the measuring cell glasstube is kept free from fouling. Cell fouling is recognised as a leading cause of monitor malfunction. Fitting the Autoclean removes the need for the ship’s crew to remember to clean the cell manually.
