Abstract

To realize volume measurement of weights from 2 kg to 20 kg, three hydrostatic methods from annex B.7.4 of OIML R111-1 are described in this paper. Equipment with regard to volume measurement of weights from 2 kg to 20 kg having three operation procedures is designed and developed on the basis of three hydrostatic methods at National Institute of Metrology (NIM) in China. The equipment consists of robot arm for transferring weights, liquid bath, mass comparator, glass housing, two weight exchangers, two weight holders and controller . The equipment will enable to finish automatically operation of volume measurements according to each operation procedure.
