Abstract : A technique and sensor is provided for directly measuring the thickness of layers of immiscible liquids of differing densities and other materials contained in a tank or other container, preferably by reflection of ultrasonic energy. A preferred form of float comprises a container filled with material sampled from the tank and includes a reflector of ultrasonic energy of greater density, whereby the reflector is accurately positioned at an interface between two immiscible liquids of differing densities. The float is restrained close to the axis of energy radiation of the'ultrasonic transducer by either a tube, forming a housing or a flexible cord. If a tube is employed, a slit in a lateral side thereof allows the tube to act as a baffle and reduce the effects of fluid motion within the tank on the measurement being made. (AN)
