The FMVC-111 is designed to convert gas volume in operating conditions to gas volume in standard conditions according to the state equation. For that purpose, it reads pulses from a gas meter, and measures gas temperature and gas pressure. The volume corrector will support PTZ, PT, TZ or T type conversions using algorithms for calculation of compressibility factors according to the standards AGA 8-92DC, AGA NX-19 mod, AGA 8-G1, AGA 8-G2, SGERG-88 or fixed.
