FLUXUS F808 - clamp-on flow meter for hazardous areas
FM Class I, Div. I approved

With the FLUXUS F808, FLEXIM moves one step further and presents its first clamp-on flow meter for liquids with FM Class I, Div. 1 approval.
The highly rugged FLUXUS F808 flameproof housing 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 PERMAFIX 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 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 1/4 inch up to 20 feet 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 processing implemented into the flow computer.
 


Advantages:

  • Highly precise and reliable bidirectional flow measurement over a wide turndown ratio
  • Very cost efficient:
    • No pipe works
    • No process shut-downs
    • Virtually no maintenance
  • Matched, paired and wet flow calibrated (NIST traceable)
  • Highly zero point stale and drift free
  • Independent of pipe size, material, pressurization and the medium
  • Independent of entrained solids and gases
  • Free of wear, tear and abrasion
  • Not prone to clogging or corrosion
  • Not responsible for pressure losses or possible leaks
  • Rugged flameproof housing, stainless steel armored cables and transducers mounting fixture
  • Installation and parameterization without having to open the housing
  • Stable, accurate and reliable measurement readings due to matched and temperature compensated transducers as well as innovative digital signal processing
  • Independent of entrained particles or gas bubbles
  • Flexible configurable outputs
