| Abstract: | Based on near-infrared spectral absorption and fiber-optic sensor technology,an experimental setup for low-water-content measurement of crude oil was developed.The advantages of this method include fast measurement,high accuracy,being free of pollution to measured oil and suitable for long-term on-line continuous monitoring.This technology can be used for those applications which needs high quality water-in-oil measurement and process control requirement.The measurement resolution of water-content can be estimated to be better than 0.005% in the range from 0% to 5% by volume. |
