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 totalizer1 ScopeThis procedure applies to the flow of the totalizer (hereinafter referred to as the total instrument) of the first test, follow-up test, use an examination. Other flow integration devices with integral calculator function can refer to this procedure.2 reference fileThis procedure refers to the following documents. On - line Gas Chromatograph GB/T 2624-2006 Measurement of full flow of fluid with differential pressure devices installed in circular cross-section piping Environmental testing of electronic measuring instruments GB 6587-1989 GB/T 11062 Calculation method of natural gas calorific value, density, relative density and Wobbe index (mod ISO 6976) Analogue input digital indicator for industrial process measurement and control systems GB/T 13639-2008 GB/T 17747 Calculation of natural gas compression factor (idtISO 12213) GB/T 18603 Natural gas metering system technical requirements Measurement of natural gas flow with standard orifice flowmeter GB/T 21446-2008 Heat meters for CJ128-2007 JB/T 2274-2014 flow display instrument For dated references, only the dated edition applies to this rule; references that are not dated , The latest version (including all amendments) applies to this procedure.3 terms and units of measurement3.1 terminology By collecting the flow-related sensor signals, calculate the flow (energy) with the relevant mathematical model. Set. Usually also known as flow display, flow computer and so on. With its matching sensors usually have standard throttle devices, Turbines, vortex, electromagnetic, ultrasonic flow sensors or transmitters and other compensation with the pressure transmitter, differential pressure transmitter, Temperature transmitter, component analyzer and so on. 3.1.2 power off protection poweroutageprotection Totalizer in the power supply during power outage, totalizer set parameters and totalizer cumulative flow and other data can be reliable Save the function. 3.1.3 sampling period samplingperiod The interval between two adjacent samples. 3.1.4 small signal cutoff lowflowratecutoff ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 1003-2016_English be delivered?Answer: Upon your order, we will start to translate JJG 1003-2016_English as soon as possible, and keep you informed of the progress.
