Abstract :
A practical method for the measurement and discrimination of floating organic layers is presented. Chromatic sensing is used to enhance the performance of the funnel-capillary technique. Kerosene layers can be measured with an accuracy of ±0.140 mm. The dynamic range of the sensor is 0.30-20 mm. The method is robust and is designed for use in an industrial environment
