The Flexim FLUXUS F608 portable liquid flow meter based on the widely used, highly reliable and versatile F601, has been specifically engineered for its use within hazardous areas and is FM Class I Division 2 approved. Offering a high degree of flexibility, without compromising on safety, users are no longer obliged to obtain a hot work permit, making access to hazardous areas much easier and less time consuming. The extremely resistant carbon fiber housing, together with the rugged transducer design, ensures high impact protection as well as resistance against oil, water and many other liquids. The F608 shares the same efficient battery management as the F601, offering over 14 hours of remote measurement time.

The Flexim FLUXUS F831 is a dual channel ultrasonic clamp-on flow meter for bi-directional flow measurement of liquids in hazardous areas (ATEX/IECEx Zone 1 and FM Class I Division 1 approved). With its explosion proof housing, optional intrinsically safe inputs and outputs and the corrosion resistant transducers residing outside the pipe wall, the FLUXUS F831 series is perfectly suited for every demanding industrial application in and out of the oil field and the chemical industry. The connection and electronics compartments of the FLUXUS F831 are hermetically sealed, and the flow meter comes with carefully matched and temperature compensated transducers (fully ANSI / ASME MFC 5M compliant) providing unmatched zero-point stability.

System configuration and installation
The FLUXUS F501IP has a set of IP68 transducers, making it ideal for subsurface installations. A stainless steel VARIOFIX C fixture optimally protects the transducers. Furthermore, the FLUXUS F501 can also be used for leak detection and the readings can be transferred to a process control system.
The Flexim FLUXUS F721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of liquids. With its state-of-the-art hardware design and 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 advanced measurement algorithms make the FLUXUS F721 liquid flow meter the standard-setting measuring solution for any industrial application - even the most challenging ones. Inbuilt and proven flow disturbance correction enables set up of non-intrusive flow measurement even under non-ideal flow conditions.
