Abstract

To fulfil calibrating of LNG dispenser verification device, the traceability system of the device was researched in this paper. Using a combination of dynamic and static quality measurement system, with high accuracy electronic balance as main standard, ultra-low temperature commutator with uncertainty of better than 1.5 × 10-4 was developed. The device could realize automation during the whole procedure of data collection under the specified flow, the calibration of LNG dispenser verification device, processing the data and generating the records and certificates.
