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 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

  • Certified for operation within hazardous areas (FMc Class I, Div. 2, ATEX, IECEx Zone 2)
  • Reliable measurements of wet gas (up to LVF 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 with unique couplant pads, FlexSpring secured mounting fixtures guarantee durable contact pressure also on heavily vibrating pipes
  • Bidirectional communication as well as remote parameterisation and diagnostic capabilities
  • Enabling complete monitoring of processes as well as supervision and control of critical operations
  • Advanced Meter Verification
