Research on Measurement Method of Oil-Water Interface Based on Oscillation Frequency


Article Preview

At the view of the present situation of the oil-water interface measurement, all sorts of measurement method can not eliminate the interference of temperature and hang oil. In order to control water ratio of purification oil at the output, simple interface detector cannot have satisfy the actual needs. A key contribution of this paper is to propose a solution based on a new type of sensor head and a test of new solution to the problem of capacitive sensing at high water ratio. A LC oscillation circuits is used to detect the variation of capacitance, overcoming the influence of the hang oil and the temperature.
