The Flexim FLUXUS F721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of liquids.
With its state-of-the-art hardware design and powerful digital signal processing it surpasses any other non-intrusive ultrasonic flow meter in terms of accuracy, reliability and versatility.
 
Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS F721 liquid flow meter the standard setting measuring solution for any industrial application–even for the most challenging ones. The meter adapts itself automatically to the respective measurement conditions and compensates for flow profile disturbances such as beam dispersal and structure-borne noise, allowing for even more precise and reliable measurements. Extreme fast measurement cycles enable precise real time monitoring of highly dynamic processes.

Features

  • No process interruption for installation, no pipe modification necessary - maintenance-free (no need for frequent work in hazardous areas)
  • Certified for operation within hazardous areas (ATEX / IECEx Zone 2 and FMc Class I, Div. 2 certified)
  • Fast measuring dynamics (output of measurement data every 10ms), capturing highly pulsating flows
  • Reliable measurements of slurries or liquids with gaseous entrainments (>10% of total volume)
  • High operational safety with no risk of leaks
  • Independent of pipe material, diameter, wall thickness and internal pressure and temperature
  • Accurate and repeatable measurement readings - even at extremely low flow rates (high turndown ratio)
  • Highly cost efficient in comparison to wetted instrumentation
  • Every measurement system is pre-calibrated in-house (traceable to national standards) and delivered with a calibration certificate
  • Matched transducers, integrated temperature compensation (according to ANSI/ASME MFC-5.1-2011 regulations) and advanced digital signal processing guarantee a high zero point stability and drift free measurement readings
  • Permanent coupling with unique couplant pads, FlexSpring secured mounting fixtures guarantee durable contact pressure also on heavily vibrating pipes
  • Bidirectional communication as well as remote set-up and diagnostic capabilities
  • Enabling complete monitoring of processes as well as supervision and control of critical operations
  • Advanced Meter Verification
