The Levalign Expert systems consists of a self-leveling, motorized, rotating laser and a sensor. Both interface wirelessly with a dedicated geometric measurement computer. The device provides an accurate and easy way to measure flatness and straightness of machine bases and foundations, split machine casings, as well as flatness and parallelism of circular, rectangular and odd-shaped flanges. The instrument displays a surface profile of the measured area in three-dimensional color graphics. A single operator can measure large vertical and horizontal surfaces. — Ludeca Inc., Doral, Fla.
