Introduction

This procedure to GB/T 13639-2008 "industrial process measurement and control system with analog input digital instructions "GB/T 2624-2006" Measurement of full-pipe fluid flow with differential pressure devices installed in circular cross-section pipes "is Technical basis, combined with the flow of our total production and use of the status quo, the JJG 1003-2005 "flow total Instrument "to be revised. In the main technical indicators equivalent to the national standard. Compared with JJG 1003-2005, this regulation In addition to editorial changes, the main technical changes are as follows. --- increase the definition of flow totalizer; --- increase the definition of quantitative control; - the input form of the flow signal increases the digital signal; --- increase the trade settlement with the total flow meter total technical requirements; --- remove the insulation resistance and dielectric strength; --- modified the selection of test points; --- increase the instantaneous heat and cumulative calorie test method; - the deletion of the original program in Appendix A "type evaluation test outline"; - the part of the provisions of Appendix B, "Selection of Measurement Parameters in Flow Error Test", in the original procedure content; --- modified part of the original procedure Appendix C "Verification Format"; --- Amend the contents of the original procedure Appendix D "Verification Certificate and Verification Result Notice Page Format". Prerequisites of this Code Release. --- JJG 1003-2005. Verification of flow totalizer

1 Scope
