Product Description

The Flexim FLUXUS G731 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of gases. Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS G731 ultrasonic clamp-on gas flow meter the standard-setting measuring solution for any industrial application. With the new Synchronised Channel Averaging (SCA) method and flow profile correction, the G731 ultrasonic flowmeter is ready for the most challenging conditions. The integrated Dynamic Gas Meter function enables the meter to calculate the media properties of the gas being measured.

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
  • Dynamic Gas Meter for calculation of gas properties like density and molar mass
  • Integrated Wet Gas Correction
  • 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
