Research on Inductive Oil-Water Interface Level Sensor

Article Preview

Abstract:

It is extremely important to know the water level in the subsea separators. Based on its highly tolerant behavior towards many different side-effects occurring in separators, inductive approach for measuring oil-water interface level is studied. The inductive sensor employed a couple of ferrite cores in the oil/water Mixture is designed. The experimental results shows induced voltage value in the second ferrite core increases with depth of core increasing in the water .The sensor has different sensitive degree to oil-water mixture under different frequency sign. The optimal frequency is from 60 to 80kHz .According to inductive voltage signal produced by a couple of ferrite cores, the oil-water interface level can be detected.
