  • Non-intrusive clamp-on ultrasonic flow measurement – no need to cut or weld the pipe
  • Highly cost efficient: No process shut-down for installation required, virtually no maintenance needed due to permanent coupling and optimal device protection
  • For explicit usage in hazardous areas – ATEX and IECEx Zone 1 approved flow meter
  • Exact and reliable bi-directional measurement of actual and standard volume flows of gases over a wide turndown ratio
  • Stainless Steel (SS316) field enclosure and transducer housing as well as rugged mounting fixtures with steel armored cables – Seawater resistant and corrosion proof
  • Highly zero point stable and drift free due to paired transducers and an integrated temperature compensation (ANSI/ASME compliant)
  • Two transducer technologies – Lamb and Shear Waves – for the most accurate measurement on the market
  • Operational safe and highly accurate measurement even at wet gas
  • Automatic recognition of the connected transducers and calibration data – high ease-of-use and user menu intuivity
  • Sophisticated diagnostic tools for optimal set-up and control of the measurement system
