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

With its flameproof housing and the corrosion resistant transducers residing outside the pipe wall, but inside the rugged VARIOFIX C 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 6 mm up to 12000mm (no limitations on pipe wall thickness or material) and media temperatures from -190°C up to +600°C (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.


Advantages

  • Bi-directional flow measurement of liquids and gases in FM Class I, Div. 1 and ATEX / IECEx Zone 1 areas
  • Very cost effective: No pipe works, No process shut-downs, Virtually maintenance-free
  • Matched, paired and wet calibrated flow transducers (traceable certification to national standards)
  • Excellent zero point stability and drift-free
  • Wide turndown ratio
  • Independent of pipe size, material, operating pressure, medium and temperature (from as low as -170 °C up to +600 °C)
  • High tolerance to entrained solids and gases
  • Free of wear, tear and abrasion
  • Not prone to clogging or corrosion
  • No pressure loss or source of potential leaks and fugitive emissions
