The Explosion-proof Expert

The FLUXUS G800 is the ideal gas flow meter for permanent installation in potentially explosive atmospheres (ATEX (IECEx) approved for Zone 1).

With its flameproof housing (IP66) the gas flow meter is designed for industrial use in harsh environments such as in gas processing plants and natural gas extraction or the chemical and petrochemical industry.

The FLUXUS G800 gas flow meter allows for an inherently bi-directional gas flow measurement of operational and standard volume flows. As the transducers are mounted on the outside of the pipe wall, the system does not suffer from wear and tear or clogging, can't be a risk for leaks and will not cause any pressure drops inside the pipe.

Due to its matched and paired transducers as well as the internal temperature compensation (compliant to ANSI/ASME) the measurement system is drift free and zero stable ensuring accurate readings. Moreover, as the transducer calibration data is automatically loaded by connecting the transducer to the transmitter, set-up times are reduced and precise, long-term stable results are provided.
