Detecting oil in water. |
摘要 |
<p>Oil concentration levels in water are measured by a light scattering/absorption technique. The intensity of directly transmitted and scattered light signals are compared to provide a correction factor corresponding to the level of solid contaminents in the mixture. This correction factor is then applied to a signal corresponding to the intensity of light transmitted directly through the mixture to provide an accurate oil concentration measurement.</p> |
