Paper Abstract

An instrument for measuring the level of a liquid surface is described. The device is compact, requires no special handling, is noncontact, and can measure variations in level of the order of a micrometer, although this value can be suitably modified by changing the setup parameters. The instrument was developed as a machine flatness profilometer using the liquid level as a reference surface. Two applications of the instrument as a machine profilometer are presented, the first in order to measure the straightness of the displacement of the spindle of a polishing machine and the second in order to find the flatness error of a coordinate-measuring machine of large dimensions.
