Three devices were evaluated in the laboratory to determine their general applicability for measuring oil-in-water in tanker operation. The devices tested were based on acoustic attenuation, sonic velocity and electrical conductivity. The laboratory tests showed that none of the devices, as supplied by the manufacturers, could meet the desired performance. The electrical conductivity device was found to be insensitive to changes in oil concentration in the 0 to 1% oil range. The sonic attenuation device gave outputs which increased with oil content in the 0 to 1% range but sensitivity varied widely and it was not possible to get reproducible results. The sonic velocity device was more sensitive but was affected by variations in specific gravity, salinity and impurities and required control of temperature and pressure. (Modified author abstract)
