FLEXIM - FLUXUS G721 - Setting Standards - Setting Standards

Setting Standards

The FLUXUS G721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of gases.

With its new hardware design and improved, powerful digital signal processing it surpasses any other non-intrusive ultrasonic flowmeter in terms of
accuracy, reliability and versatility.

Highly sophisticated signal filters, faster than ever processing capacities and substantially improved measurement algorithms make the FLUXUS G721 flow meter a state-of-the-art measuring solution even for the most challenging applications.
The meter adapts itself automatically to the respective measurement conditions and compensates for perturbations such as beam dispersal and
structure-borne noise, allowing for even more precise and reliable measurements. Extreme fast measurement cycles allow for precise real time monitoring of highly dynamic processes.

Pushing the Boundaries

The FLUXUS G721 offers non-intrusive flow measurement of virtually any kind of gaseous media, independent of the pipe size, material and with no upper  pressurisation limit. Due to its advanced technology, the measurement is unaffected by gas wetness and distinguishes itself by its unrivalled turndown ratio: Even low flows down to only a few cubic meters per hour can be recorded accurately.

As the flowmeter of choice for a very wide range of applications in virtually any industrial sector, the FLUXUS G721 is available with two different enclosure types: aluminium housing for standard applications and stainless steel housing for operation in highly corrosive environments. The stainless steel product variant is certified for usage in hazardous areas (ATEX, IECEX Zone 2, FM Class I, Div. 2).

Ready for Industry 4.0

The FLUXUS G721 comes with all common communication protocols: HART, Modbus, Foundation Fieldbus, Profibus PA and BACnet allow bidirectional field communication, parameterisation and online diagnostics. Further special configurations guarantee optimal customisation to the individual application. The FLUXUS G721 is also one step ahead in terms of user guidance and diagnostics. It can be easily parameterised via USB. Its ethernet connectivity provides additional bidirectional communication capabilities.

Further value is added by the meters advanced selfmonitoring capabilities and the possibility of event driven data recording. The flow meter is permanently controlling the quality of the measurement. Such values, but also every other measurement data as well as externally fed in data, e.g. pressure and temperatues, can be chosen to trigger free defined meter functionalities. For instance, in case the quality of the measurement is falling below a predefined value, a temporary recording of high resolution measurement data can automatically be started. Such free configurable event based trigger functionality is not only perfectly suited for measurement diagnostics, but even more for the accurate monitoring of processes and especially the supervision and control of critical operations.
