Functional Safety – SIL2 certified clamp-on flowmeter
As the world’s first ultrasonic clamp-on flowmeters the FLUXUS series from FLEXIM has now been independently proven suitable for use in process control protection loops according to the IEC 61508 norm and are certified as “SIL 2 Ready”.
The FLUXUS F/G70X and F/G80X series meters have been independently audited and certified for permanent non-invasive installation on liquid and gas flow measurement applications. As the ultrasonic transducers are simply and firmly clamped to the outside of the pipe wall, the measuring system is not exposed to any abrasion from the inside flowing medium and is thus virtually maintenance free. Furthermore, the installation of the clamp-on flowmeter could not be easier as it does not require any pipework alteration, production or process interruptions.
Due to the ultrasonic transit-time technology, the measurement works bidirectionally with the same high degree of accuracy over an extremely high dynamic range. The FLUXUS clamp-on meters measure independently from the medium flowing inside the pipe, as well as the pipe material size, wall thickness and operating pressure. The available flow transducers cover a size range from 6 mm to 6.5 m.
The SIL2-certified measurement systems are also available for use in potentially explosive atmospheres (ATEX, IECEx Zone 1 and 2).
When used in conjunction with the patented “WaveInjector” transducer mounting fixture, the FLUXUS meter can also measure at extreme pipe wall temperature ranges from -170 °C up to 600 °C. Thanks to carefully matched transducer pairs, unique internal temperature compensation and sophisticated internal signal processing, the clamp-on ultrasonic FLUXUS meters are highly zero point stable and drift free, ensuring precise measurement data.
FLEXIM calibrates the paired transducers and transmitters independently from each other and can therefore guarantee that the highly accurate measurement uncertainties can be achieved, no matter which transducer combination is used with whichever transmitter.
