JJF 1993-2022 Metrological Specification for the Energy Measurement of Natural Gas
Abstract
This standard specifies the evaluation of natural gas energy measurement systems used for trade measurement, the verification of natural gas energy measurement results, and the methods for assessing their grades.
This standard applies to pipeline-transported natural gas specified in GB/T 18603 with a design throughput capacity of not less than 100 m3/h (under metering reference conditions) and an operating pressure of not less than 0.1 MPa (gauge pressure). Other metering reference conditions or other natural gas energy measurement systems can also be referenced for implementation.
This standard does not address all safety issues related to its application. Measuring instruments such as temperature transmitters, pressure transmitters, and flow meters used for natural gas energy measurement should all comply with corresponding explosion-proof and other safety requirements.
