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 sea spray resilient 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.
