Further development of an on line Oil-in-Water Content Monitor is presented. The basic techinque of optical scattering monitoring has been maintained. Performance verification in various test situations was conducted. Interferences such as particulate matter, gravity, pH of water, salinity of water, and temperature of water were investigated the only serious interference being small particulate matter. Effects of oil droplet size, detergents and type of oil on monitor performance were also investigated. At its present level of development the monitor will produce errors of less than or - 10 within a single oil type at 125 PPM level. At the same level, errors less than or - 14 can be expected from oil mixtures without Bunker C. Oil mixtures including Bunker C produced an error band of or - 33.
