  • Abstract:
    This paper describes the intercomparison tests carried out by 10 labs around China from 2003 to 2004. We compared the bell provers with a flow range from 0. 6 to 6 m³/h by using 2 roots flow meters. Test result and diagram are showed in this paper. We analyzed the influence of temperature control and the seal liquid of bell provers on test.
