DEVELOPMENT AND REALISATION OF A FULLY AUTOMATIC TESTING FACILITY FOR DETERMINING THE VOLUME OF E1 WEIGHTS UP TO 50 KG BASED ON HYDROSTATIC WEIGHING

Christian Buchner

Abstract

The Federal Office of Metrology and Surveying (BEV, Austria) has developed and realised a new fully automatic test System for hydrostatic weighing and determining the density of solids up to 50 kg. This volume comparator allows a full automatically determination of the volume of E1 weights and plummets in the range from 1 kg up to 50 kg through direct comparison with one single volume reference (e.g. a Silicium sphere) with high accuracy. In this volume comparator, two hydrostatic weighing systems for density determination work simultaneously together so that it is possible to compare the density of a small, well-known standard sinker directly with the density of a submerged solid with masses up to 50 kg.
