Advantages

  • No process interruption for installation, no pipe works – maintenance-free (no need for frequent work in hazardous areas)
  • Certified for operation within hazardous areas (ATEX / IECEx and FMc Class I, Div. 2)
  • Fast measuring dynamics (output of measurement data every 10ms), capturing highly pulsating flows
  • 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
