The FLUXUS® G801 is the ideal ultrasonic gas flowmeter for permanent installation in rough and hazardous offshore environments The FLUXUS® G801 is completely seawater and sea-spray resistant and ideal for applications found on Oil and Gas Extraction platforms offshore. It is certified for usage in potentially explosive areas as well (ATEX (IECEx) Zone 1).

The FLUXUS® G801 allows for bi-directional gas flow measurement of operational and standard volume flows.  The gas flow meter can be applied at inner pipe diameters ranging from 6 mm up to 2100 mm (no limitations on pipe wall thickness or material) and media temperatures from -40°C up to 100°C.

Benefits of FLUXUS® G801:

  • Unaffected by gas density, viscosity and composition as well as temperature and pressure.
  • Non-intrusive, clamp-on technology – no need to cut or weld the pipe for installation.
  • Virtually no maintenance needed due to permanent coupling and optimal device protection.
  • For explicit usage in hazardous areas – ATEX and IECEx Zone 1 approved.
  • Exact and reliable bi-directional measurement of actual and standard volume flows of gases over a wide turndown ratio.
  • Zero-point stable and drift free due to paired transducers and an integrated temperature compensation (ANSI/ASME compliant).
  • Operationally safe and highly accurate measurement, even of wet gas.
  • Sophisticated diagnostic tools for optimal set-up and control of the measurement system.


Permanent Flowmeters for Gases

FLUXUS® permanent, clamp-on ultrasonic systems allow for the flow measurement of almost all liquid and gaseous media – even those with increased inputs of solids and gas (<10%) or even wet gas (LVF <5%). FLUXUS® reliably measures on very small tubes (e.g. DN 6 tubes in paint finishing systems) and very large pipes (e.g. DN 6500 downpipes in hydropower plants). The practical advantages include:
  • No wear and tear by the medium flowing inside the pipe
  • No risk of liquid leakage or fugitive gas emissions
  • No pressure loss
  • Unlimited plant availability
