Product Description

The Flexim FLUXUS G721 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 G721 ultrasonic clamp-on gas flow meter the standard-setting measuring solution for any industrial application - even the most challenging ones. Inbuilt and proven flow disturbance correction allows the set up of non-intrusive flow measurement, even under non-ideal flow conditions. Extremely fast measurement cycles enable precise real-time monitoring of highly dynamic processes.

Features

  • Certified for operation within hazardous areas (FMc Class I Division 2, ATEX/IECEx Zone 2)
  • Reliable measurements of wet gas (up to liquid volume fraction of 5%).
  • High operational safety with no risk of leaks.
  • Independent of pipe material, wall thickness and internal pressure.
  • 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 digital signal processing guarantee a high zero point stability and drift-free measurement readings.
  • Permanent coupling ensures long-term reliable non-intrusive flow measurement, even under harsh environmental conditions such as submersion.
  • Bi-directional communication as well as remote parameterization and diagnostic capabilities.
  • Enabling complete monitoring of processes as well as supervision and control of critical operations.
  • Advanced Meter Verification.
