ABSTRACT:
An apparatus for detecting the concentration of a surfactant in a liquid solution comprising a wheel rotatably mounted in a tank and having a portion which extends outwardly thereof. A series of progressively larger holes arranged on a circle concentric with the axis of rotation of the wheel are formed therein as are notches in the periphery of the wheel. Photoelectric cells are used to count the films formed across the holes and the notches in the wheel to provide an indication of the concentration of a surfactant.
