The non-intrusive Flexim FLUXUS F731 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 F731 ultrasonic clamp-on liquid flow meter the standard-setting measuring solution for any industrial application. With the new Synchronised Channel Averaging (SCA) method and flow profile correction, the F731 ultrasonic flowmeter is ready for the most challenging conditions.

Features

  • Accuracy and repeatability - exceptional reliability and accuracy at high and low flows due to matched, calibrated and temperature compensated transducers, advanced signal processing capabilities and diagnostics.
  • Easy installation without process interruptions - an externally mounted system means no need for process interruptions or additional engineering costs.
  • Maintenance-free - no contact with flowing media results in a completely maintenance- free and durable metering solution to withstand even the harshest environments.
  • Operational safety - no leak paths, no fugitive emissions.
  • Advanced Meter Verification
  • Certified for operation within hazardous areas (FMc Class I Division 2, ATEX/IECEx Zone 2)
  • 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 digital signal processing guarantee a high zero-point stability and drift-free measurement readings.
  • ISO 24062 compliant
  • Flow disturbance correction to reduce required straight runs down to 2D inlet
