Ultrasonic Flow Meter (FLUXUS SIL G)

Functional Safety with FLUXUS

Functional Safety approved Gas Flowmeter

The FLUXUS non-invasive ultrasonic gas flow meters have always been the first choice when it comes to maintaining accurate measurements in harsh conditions – e.g. during the flow measurement of highly pressurised, aggressive, toxic or highly explosive gaseous media.

FLUXUS measures from the safe side: From outside.

The clamp-on ultrasonic transducers are simply mounted on the outside of the pipe. Without any risk of leak and during ongoing operation. The ultrasonic measuring method doesn’t need any wetted devices, works independent of the pressure inside the pipe and is not subjected to mechanical stress which means it is practically wear-free.
As the wetted parts of inline measuring devices are not subject to the Failure Mode Effects and Diagnostics Analysis (FMEDA), they are not included in the scope of certification - presenting a safety risk. On the other hand, the SIL 2 certification of the FLUXUS non-invasive flow meter includes the entire measuring system -the measuring transmitters and transducers.

Safety without interruption.

The advantages of FLEXIMs non-invasive flow measurement technology pay off all the more over the entire lifecycle:
There is never any need to interfere with the pipeline system when carrying out periodic inspections. The self-diagnosis functions of the FLUXUS mean retests can be carried out easily to accurately assess the reliability and quality of the measurement. Even more detailed functional tests such as alarm tests or tests for monitoring compliance with measuring accuracy requirements never interfere with plant availability.
