THE NEW pVTt FACILITY IN NIM

Chunhui Li, Luishi Cui, Chi Wang
Abstract:
In NIM, the old 2 m3 and 20 m3 facilities were built in 1986. The temperature stability of the collection tank was easily influenced by the surroundings. So, the new 0.1 m3 and 2 m3 pVTt facilities were built in 2013. The collection tanks were covered in water bath. The uncertainty for the new pVTt facilities were analyzed, and the measurement capablity was verified by comparisons among the new pVTt facility, the old pVTt facility and gas flow facilities in PTB with 14 sonic nozzles.
