With the FLUXUS F808, FLEXIM presents a clamp-on flow meter for liquids with IECEx / ATEX Zone 1 approval.
From wellhead to refinery, the flows of crude oil and refined products need to be measured every step of the way. Harsh environments with corrosive atmospheres offshore or hot and dirty applications during crude oil refining require tough solutions. Also during chemical processing, media such as acids, caustics or highly viscous organic substances place enormous material and mechanical stress upon wetted flow measurement technologies.
The highly rugged FLUXUS F808 with its flameproof housing and stainless steel transducers is suited for every industrial application.
With its connection and electronic compartment being hermetically sealed, the FLUXUS F808 provides for a maximum of operational safety and is especially designed for usage in rough industrial environments such as in Chemical and Petrochemical plants.
In conjunction with the extremely robust transducers and the VARIOFIX transducer mounting fixture (Stainless Steel SS316 available), which ensures a permanent contact pressure to the pipe wall and an extreme mechanical stability, the FLUXUS F808 is the most reliable ultrasonic clamp-on flow meter available. As the ultrasonic transducers are mounted on the outside of the pipe wall, the system does not suffer from wear, tear or clogging and can't be a risk for leaks.
But the FLUXUS F808 is not only rugged – due to carefully matched and temperature compensated transducers (fully ANSI / ASME MFC 5M compliant) the FLUXUS F808 offers an unmatched zero stability. Highly innovative digital signal processing within the flow meter cares most reliable, repeatable and accurate bidirectional flow measurement over a wide turndown ratio.
The FLUXUS F808 flow meter can be applied at inner pipe diameters ranging from 6 mm up to 6,5 m and more. 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 processingimplemented into the flow computer.
