Abstract
An ultrasonic level sensor includes: a housing; an ultrasonic transducer having a face surface for emitting an ultrasonic signal; a reflector with a flat surface positioned at an angle with respect to the face surface of the ultrasonic transducer for reflecting and directing the ultrasonic signal to a surface of a material in a container; and a scattering structure to reflect unwanted scattered ultrasonic signals away from the surface of the liquid, wherein the ultrasonic signal is reflected from the surface of the material and from the flat surface of the reflector and received by the ultrasonic transducer.
