Functional Safety - SIL2 Certified Clamp-On Flowmeter

As the world’s first ultrasonic clamp-on flowmeters, the FLUXUS series from FLEXIM have proven their suitability for use in process control protection equipment according to the IEC 61508 norm and are certified as "SIL 2 capable".

The FLUXUS F/G70X and F/G80X series meters, which are to be used for the permanent, non-invasive flow measurement of liquids and gases, are audited and certified. Since clamp-on ultrasonic transducers are simply attached to the outside of the pipe wall, the measuring system is not exposed to any wear and tear by the medium flowing inside and is thus virtually maintenance-free. In addition to that, there is no need to open the pipe when installing the clamp-on flowmeter and therefore no interruption to production or processing.

Due to the ultrasonic transit-time technology used, the measurement works bidirectionally with the same high degree of accuracy over an extremely high dynamic range. FLUXUS clamp-on meters measure independently from the medium flowing inside the pipe, as well as the pipe material, its dimension and wall thickness and the operating pressure. The available flow transducers cover a nominal size range from 6 mm to 6.5 m.
It goes without saying, the SIL2-certified measurement systems are also offered in versions approved for use in potentially explosive atmospheres (ATEX, IECEx Zone 1 and 2).

In conjunction with the patented transducer mounting fixture “WaveInjector”, 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, clamp-on ultrasonic FLUXUS meters are highly zero-point stable and drift-free, ensuring precise measurement data.
FLEXIM calibrates transducer pairs and transmitters independently of each other which in turn guarantees that narrowly specified measurement uncertainties can in any case be respected, no matter which transducer is used with a particular transmitter.
