FLUXUS XLF is FLEXIM‘s non-invasive metering system for the reproducible and long term reliable measurement of extremely low flow rates down to 3 l/h and below on line sizes ranging from 10 mm to 50 mm independent of the pipe wall thickness. As the flow sensors are mounted externally, there is no process interruption for installation.

Moreover, due their IP66 protection degree, ATEX / IECEx Zone 1 / 2 as well as FM Class I, Div. 1 / 2 approval and being completely made out of stainless steel (316L / 1.4404 grade), the measurement system is highly rugged and withstands even the harshest and most corrosive environmental conditions.

FLEXIM is the much more cost-effective and safer alternative for measuring extremely low flows of any liquid

The FLUXUS XLF is applicable on all pipe materials and wall thicknesses as well as independent of operating pressures.
In comparison to wetted instrumentation, the system does not suffer from mechanical stress or wear and tear by the medium and is thus not only much more cost efficient, but also offers significantely higher operational safety as the risk of leaks can completely be eliminated.

Its high accuracy and repeatability at extremely low flow velocities is achieved by carefully matched and temperature compensated transducers (acc. to ANSI/ASME MFC 5.1-2011), highly sensitive electronics and sophisticated internal signal processing as well as a highly precise and traceable wet flow calibration (according to NIST standards) at FLEXIM‘s low flow calibration facility.


Advantages

  • No process shut-downs or interruption of supply
  • No potential for leaks
  • Completely maintenance free
  • Accurate and highly repeatable measurement of extremely low flows
  • Applicable to any pipe and any liquid media
  • Rugged and hazardous area approved transducers and transmitters (ATEX /  IECEx Zone 1/2, FM Class I, Div. 1/2)
  • Matched transducers, advanced digital signal processing (DSP) and efficient algorithms ensure stable measurements at very low flows
