STABILITY FACTORS IN GAS METER VERIFICATION LABORATORIES: MATHEMATICAL MODELING AND ERROR CONTRIBUTION ASSESSMENT
Keywords:
gas meter, verification facility, instability, flow pulsation, measurement error, compressibility factor, Monte Carlo simulation.Abstract
Instability in verification facilities used for gas meter calibration arises from multiple physical and metrological factors, including pressure and temperature fluctuations, flow pulsations, gas compressibility and composition changes, hydraulic regime variations in pipelines, sensor drift, regulator dynamics, and reference channel uncertainties.
