Abstract

A method and system for determining the dimensional volume of a package by moving the package on a conveyor belt system over a horizontally disposed strip containing machine-readable indicia indicating units of incremental length along said strip starting from a zero point and by a vertically disposed strip containing machine-readable indicia indicating units of incremental length along said strip starting from a zero point, with a horizontally disposed reader above the horizontally disposed strip to read the uncovered indicia on the horizontally disposed strip and a vertically disposed reader able to read the uncovered indicia on the vertically disposed strip with a computer to determine the lowest uncovered incremental length measurement of the indicia on tile horizontally disposed strip, such measurement being tile width of tile package and the lowest uncovered incremental length measurement of tile indicia on tile vertically disposed strip, such measurement being tile height of tile package, and a device to measure tile package's length as it moves on the conveyor belt system such that the computer calculates tile package's dimensional volume by taking tile product of tile measurements for the length, tile height and tile width of the package. A weigh-in-motion scale is utilized on the conveyor belt system, the output of which is also directed to the computer to calculate tile package's dimensional weight.
