The non- intrusive ultrasonic gas flow meter for operation in hazardous areas

The FLUXUS G809 is FLEXIM's dual channel ultrasonic clamp-on flow meter for bi-directional flow measurement of gases in hazardous areas ATEX, IECEx Zone 1.

The FLUXUS G809 series is perfectly suited for demanding industrial and process applications. With its flameproof housing, compact design, and the corrosion resistant ATEX, IECEx Zone 1 – FM Class 1. Div. 1 rated transducers mounted in “fit for purpose” rugged mounting fixtures, the system’s mechanical stability and permanent contact with the pipe surface is assured.

The FLUXUS G809 gas flow meter allows for inherently bi-directional gas flow measurement of operational (gross) volumetric flowrate. Standard (net) volume flow can also be provided at a user-entered fixed temperature/pressure. The FLUXUS G809’s two measurement channels make the device perfectly suited for difficult measurement points, and it is completely unaffected by gas density, viscosity and composition as well as temperature and pressure.  Even in wet gas applications with up to 5% Liquid Volume Fractions, the G809 gas flow meter is applicable and accurate. The non-intrusive design of the G809 flow meter means the transducers are mounted on the outside of the pipe wall. This way the system does not suffer from wear and tear or clogging and creates no risk for leaks or pressure drops inside the pipe.

Due to its matched and paired transducers as well as internal temperature compensation (compliant to ANSI/ASME), the measurement system is drift free and zero stable ensuring accurate readings. The gas flow meter can be applied on inner pipe diameters ranging from 6 mm up to 2100 mm (with no limitations on pipe wall thickness or material) and media temperatures from -40°C up to 100°C.
