Permanently installed and freely configurable gas flow measurement

The FLUXUS® G704  is FLEXIM's gas flow meter for permanent installation in nearly any gas flow metering application. Its non-intrusive measurement technology ensures a precise bi-directional, highly dynamic gas flow measurement of operational and standard volume flows.

As the transducers are mounted on the outside of the pipe wall in rugged mounting fixtures, 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.

The gas flow meter can be applied at inner pipe diameters ranging from 7mm up to 1600mm (no limitations on pipe wall thickness or material) and media temperatures from -40°C up to 200°C. Moreover, the measurement system is independent of the pressure inside the pipe.

With up to two measurement channels, the FLUXUS G704 permanent gas flow meter can also be applied to difficult measurement points and is completely unaffected by gas density, viscosity and composition as well as dust and humidity. Even wet gas up to Liquid Volume Fractions of 5% can be measured.

Further, with its wide range of electrical inputs and outputs, the G704 gas flow meter can handle a variety of process parameters within gas flow metering applications.

The FLUXUS G704 gas flow meter is also available in an ATEX Zone 2 / FM Class I Div II approved version, allowing its usage in the respective hazardous areas. FLEXIM also offers gas flow meters for usage in ATEX Zone 1 environments, such as the FLUXUS G800 and FLUXUS G801 (for Offshore usage).
