FLUXUS G801 - 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 seaspray-resistant 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 7mm up to 1600mm (no limitations on pipe wall thickness or material) and media temperatures from -40°C up to 200°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.

 

Applications:

The FLUXUS G801 is desgned for industrial use in harsh environments - especially Offshore at gas extraction platforms or in gas processing plants.

  • Measurement of gas flows at Offshore platforms
  • Measurement of synthesized gas and injection gas
  • Measurement for the gas utility industry
