FLEXIM - FLUXUS G809 - Gas Flowmeter for Hazardous Areas - Permanent Gas Flow Meter for Hazardous Areas

Permanent Gas Flow Meter for Hazardous Areas

The 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 and FM Class I, Div. 1 / 2 approved).

With its flameproof housing and the corrosion resistant transducers residing inside the rugged VARIOFIX C mounting fixture, ensuring a permanent contact pressure and high mechanical stability, the FLUXUS G809 series is perfectly suited for every demanding industrial application.

The FLUXUS G809 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. The gas flow meter can be applied at 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.

With up to two measurement channels, the FLUXUS G809 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 temperature and pressure.  Even wet gas up to Liquid Volume Fractions of 5% can be measured.
