Fluid Components International thermal flow meters and switches

Fluid Components International SIL-compliant thermal flow meters and switches for safety instrumented systems comply with standards IEC 61511 and 61508.

Reliable failure rate data is critical when it comes to evaluating the impact an individual sensor will have on the overall safety instrumented system (SIS) design. Equally important is validating the particular safety instrumented function (SIF) being used to calculate safe failure fraction (SFF) of a product, evaluating required hardware fault tolerance (HFT) and allowing a design engineer to perform PFDavg calculations.

To ensure that unbiased failure rate data is available, the company utilises independent, authorised third parties to perform the FMEDA (failure modes, effects and diagnostics analysis) per IEC 61508 for its thermal flow meters and thermal switches.
