Abstract:
The paper presents construction, metrological testing and field practice of a Liquefied Petroleum Gas (LPG) transfer standard (TS). This meter package was tested first with water as working medium and re-tested with propane and butane at the National Measurement Institute of Australia (NMIA). The rational is that NMIs maintaining LPG legal measurement infrastructure could simplify the traceability method by utilizing water as test medium while keeping the same accuracy. In addition, the meter package is intended to replace the conventional gravimetric approach, which requires tedious in-situ testing process for a LPG fuel dispenser. The project is supported by Asia Pacific Metrology Program (APMP) Technical Committee Initiative fund.
