Abstract

The present invention comprises a method and apparatus for measuring the linear dimensions and determining the three-dimensional spatial volume of an object. In the preferred embodiment, all three linear dimensions are ascertained using the travel time of reflected ultrasonic waves. Measurements may be taken while the object is in motion, and the object may also be weighed.
