In order to detect the oil water interface in the oil storage tank and to draw off the water as re-quired, an oil water interface detection system based on near-infrared spectral absorption was designed, in which, basing on the oil and water' s different absorption and through selecting proper infrared spectrums and optical paths, the near-infrared detect probe can determine oil water interface and prevent its emulsification from influencing the detection.The experimental results indicate that this system can improve the detection precision of oil water interface in the crude oil tank.
