Abstract
An arrangement for determining the supercompressibility factor of a flowing gas at elevated pressure includes a first meter for measuring the volume flow rate of the gas at the elevated pressure, a restrictor at the outlet of the first meter for dropping the pressure of the gas to a pressure at which the supercompressibility factor is known, and a second meter for measuring the volume flow rate of the gas at the lower pressure. A computer calculates the supercompressibility factor of the gas at the elevated pressure by utilizing measured values of temperature, pressure and volume flow rate of the gas at both the elevated and lower pressures.
