The permanent Gas flow meter G709 -
The Rack Version
The FLUXUS G709 gas flow meter is the 19" rack version of the G704 permanent gas flow meter. Internally identical to the FLUXSU G704, its non-intrusive measurement technology ensures a precise bi-directional, highly dynamic gas flow measurement of operational and standard volume flows.
As the transducers are mounted on the outside of the pipe wall and enclosed in the stainless steel VARIOFIX mounting fixtures, the system does not suffer from wear and 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) the measurement system is drift free and zero stable ensuring accurate readings. Moreover, as the transducer 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 from1/4 up to 63 inches (no limitations on pipe wall thickness or material) and media temperatures from -40°F up to 390°F. Moreover, the measurement system is independent of the pressure inside the pipe.
The accurate and reliable measurement of the FLUXUS G704 gas flow meter is completely unaffected by gas density, viscosity and composition as well as dust and humidity. Even wet gas up to Liquid Volume Fractions of 5% can be measured.
Further, with its wide range of electrical inputs and outputs, the G704 gas flow meter can handle a variety of process parameters within gas flow metering applications. The transmitter itself, as a Rack version, can be situated in a control cabinet at quiet a distance from the actual measurement point and will be connected through junction boxes.
