Introduction

This specification is based on the needs of my country's natural gas energy measurement, combined with my country's energy measurement technology level and industry status quo formulate. JJF 1071 "Rules for Writing National Metrology Calibration Standards", JJF 1001 "General Metrology Terms and Definitions" and JJF 1059.1 "Assessment and Expression of Measurement Uncertainty" together constitute the basic norms supporting the formulation of this specification. This specification refers to GB/T 18603 "Technical Requirements for Natural Gas Metering System" GB/T 22723 "Measurement of Natural Gas Energy "determined" to be formulated. This specification is published for the first time. Technical specification for natural gas energy measurement

1 Scope

This specification stipulates the evaluation of the natural gas energy measurement system used for trade measurement, the evaluation of natural gas energy measurement results Verification and assessment methods for its grades. This specification is applicable to the design passing capacity specified in GB/T 18603 not less than 100m3/h (measurement reference bar Under the conditions), the working pressure is not lower than 0.1MPa (gauge pressure) for pipeline transportation of natural gas. Other metrological reference conditions, or Other natural gas energy metering systems can also be implemented as a reference. This specification does not address all safety issues related to its application. Temperature transmitters for natural gas energy metering, Measuring instruments such as pressure transmitters and flow meters shall meet the corresponding safety requirements for explosion protection.
