The food and beverage metal packaging industry produces millions of units daily. A key to controlling a highly complex manufacturing process is to conduct offline dimensional measurement of sampled products. In this paper, a methodology to verify the performance and validate the traceability of a non-contact measurement system, is demonstrated. A single-point laser triangulation sensor (laser) is used as part of a setup to measure the height of a finished can. The measured heights are compared on a contour measuring instrument to enhance the confidence of the results. An experiment, conducted in laboratory conditions, concluded that measuring a specific can height with the laser produced a systematic error which is within acceptable parameters.
