The Natural Gas Flow Computer ES-749 satisfies the instrument requirements for natural gas applications. The NX-19 option is available for Natural Gas calculations where the user requires compensation for compressibility effects. Compensation for these compressibility effects are required at medium to high pressure and are a function of the gas specific gravity, % CO2, % Nitrogen, as well as temperature and pressure. The compressibility algorithm used is that for AGA NX-19.
The alphanumeric display offers measured parameters in easy to understand format. Manual access to measurements and display scrolling is also supported.
