Abstract

An optical sensor has been developed that can conveniently measure the depth of organic liquid layers floating on aqueous solution. Layer depth can be measured with an accuracy of +/- 0.14 mm. The dynamic range of the sensor is 0.3 mm to 20 mm. The method is robust and is designed for use in an industrial environment.
