EVALUATING THE UNCERTAINTY IN THE MEASUREMENT OF CUMULATED VOLUME OF NATURAL GAS

• Abstract:

  An equation to obtain the uncertainty in the measurement of cumulated volume of natural gas by orifice plate meters and gas chromatography is proposed. Results depend mainly on the sampling rate of chemical properties and on the expected variations in natural gas composition. The method may serve to perform a cost-benefit study of implementing on-line gas chromatography analysis.
