FLEXIM - FLUXUS G801 - Offshore Gas Flowmeter - The Ultrasonic Gas Flow Meter for Offshore Environments

The Ultrasonic Gas Flow Meter for Offshore Environments

The Offshore Gas Flow Meter

The FLUXUS G801 is the ideal ultrasonic gas flow meter for permanent installation in rough and hazardous offshore environments 

Similar in its technical features to the FLUXUS G800 gas flow meter, the especially robust FLUXUS G801 is completely seawater and sea spray resistent and especially designed for applications found on Oil & Gas extraction platforms offshore.

The flow meter is encased in a Stainless Steel housing and can be operated by a magnet pen without opening the housing. It is certified for usage in potentially explosive areas (ATEX (IECEx) Zone 1). 

The FLUXUS G801 gas flow meter allows for an inherently bi-directional gas flow measurement of operational and standard volume flows. As the transducers are mounted on the outside of the pipe wall, enclosed in the rugged stainless steel VARIOFIX C mounting fixture, the system does not suffer from wear, tear or clogging, can't be a risk for leaks and will not cause any pressure drops inside the pipe.

Due to its matched and paired transducers as well as the internal temperature compensation (compliant to ANSI/ASME regulations) the measurement system is drift free and zero stable ensuring accurate readings. Moreover, as the transducers calibration data is automatically loaded by connecting the transducer to the transmitter, set-up times are reduced and precise, long-term stable results are provided.

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. Moreover, the measurement system is independent of the pressure inside the pipe.

With up to two measurement channels, the FLUXUS G801 permanent gas flow meter can also be applied to difficult measurement points, is completely unaffected by gas density, viscosity and composition as well as temperature and pressure. Even wet gas up to Liquid Volume Fractions of 5% can be measured.

Advantages

  • 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
