FLEXIM - FLUXUS F809 - Dual Channel Flowmeter for Hazardous Areas - Permanent Flow Meter for Hazardous Areas - cFM Class I, Div 1/2 approved

Permanent Flow Meter for Hazardous Areas - cFM Class I, Div 1/2 approved

The ultrasonic flow meter for operation in hazardous areas

The FLUXUS F809 is FLEXIM's dual channel ultrasonic clamp-on flow meter for bi-directional flow measurement of liquids in hazardous areas (FM Class I, Div. 1 and ATEX, IECEx Zone 1 approved).

With its flameproof housing and the corrosion resistant transducers residing outside the pipe wall, but inside the rugged PERMAFIX mounting fixture, ensuring a permanent contact pressure and high mechanical stability, the FLUXUS F809 series is perfectly suited for every demanding industrial application.
The connection and electronic compartment of the FLUXUS F809 is hermetically sealed, so that the measurement system provides maximum operational reliability and safety.

Not only is the FLUXUS F809 rugged and reliable, it is precise.
Thanks to carefully matched and temperature compensated transducers (fully ANSI / ASME MFC 5M compliant), the FLUXUS F809 offers an unmatched zero point stability and precise bi-directional flow measurement of virtually any liquid media - ranging from crude oil to refined products and chemical media - over an unlimited turndown range.

The FLUXUS F809 flow meter can be applied at inner pipe diameters ranging from 0.25 inch up to 500 inches (no limitations on pipe wall thickness or material) and media temperatures from -275 °F up to 1100 °F (by usage of the high temperature mounting fixture WaveInjector).

With up to two measurement channels, the FLUXUS F809 flow meter can also be applied to difficult measurement points with non-ideal flow profiles. Even liquid streams with a high content of solids or gas bubbles are not a problem due to the innovative HybridTrek mode and the unique signal processing implemented into the flow computer.
