Fujian built the country's first "online standard device for natural gas flow"
A few days ago, after being approved by the General Administration of Quality Supervision, Inspection and Quarantine, the country's first "online standard device for natural gas flow" was built at the Fujian Academy of Metrology. The standard device is suitable for online detection of natural gas flow meters. Its measurement range is: sound velocity (300 ～ 500) m / s, flow velocity (0.3 ～ 30) m / s, in which the expanded uncertainty of sound velocity calculation results reaches 0.1% ( k = 2), the expanded uncertainty of the device is Urel = 0.32% (k = 2).
After the establishment of the standard device, online measurement of Fujian natural gas measurement system can be carried out, in particular, remote online sound velocity verification and flow verification of ultrasonic gas flowmeter for natural gas can be carried out. Save a lot of costs for enterprises to submit inspections. At the same time, the device is of great significance for studying natural gas energy measurement methods, improving the technical level of natural gas measurement in China, accelerating the pace of international standards and promoting energy conservation and consumption reduction.
