GEOMETRIC MEASUREMENT OF THE VOLUME OF OIML CLASSES E AND F WEIGHTS WITHOUT SURFACE CONTACT

Omar J. Purata, José de la O., Elvia Funes
Abstract:
A noncontact test method for the volume determination of weights from (1 to 1 000) g is described. The method uses an optical comparator to size cylindrical weights, and allows to compute the volume of the weight according to OIML R 111-1 Method E. The volume values obtained for the weights were compared against hydrostatic weighing volume results for reference. The volume relative uncertainty levels reached with the optical comparator are small enough for calibration operations of even OIML Class E2 weights.
