Abstract
A system for counting a series of progressively moving articles using one or more sidewardly positioned and angularly oriented ultrasonic transducers which bathe the articles with ultrasonic waves and receive echoes reflected backwardly therefrom. Distances to the articles are determined by measuring round-trip sonic travel times. Count adjustment signals are generated when articles pass through the fields of view of the transducers and are replaced by other articles at measurably different distances.
