Process and control today | Industry’s largest selection of SIL rated thermal flow meters for safety critical applications


For process SIS applications in chemical plants, power plants, refineries, oil/gas, mining, cement and more

process and plant Engineers in demanding industries responsible for Safety Instrumented Systems (SIS) that require air/gas flow measurements will find this Fluid Components International (FCI) offers them the Industry’s largest selection of SIL classified thermal air/gas flow meters.

For more than five decades, FCI has been a leading global manufacturer of thermal mass flowmeters for industrial processes and plant operations. For the past 10+ years, FCI has invested in the development of SIL compliant products across its product line and today offers more SIL rated thermal mass flow meters than any other manufacturer. From simple air to complex gas mixtures and from standard 4-20mA analog outputs to digital bus communications such as HART, Modbus and more, for SIL 1 or SIL 2 applications there is an FCI flowmeter solution. In addition to SIL ratings, FCI products are approved by global authorities for Ex-certified installations.

The most frequently cited and requested international standards for SIS in industrial processes and applied to thermal flow meters are: IEC 61511: Functional safety – Safety instrumented systems for the process industry; ANSI/ISA-84.00.01 (IEC 61511 Mod) – Functional Safety: Safety Instrumented Systems for the Process Industry; and IEC 61508: Functional safety of electrical, electronic and programmable electronic safety-related systems.

With an ever-increasing demand and a global focus on plant and operational safety in the chemical, power, oil/gas, petroleum refining and other industries, instrumentation specifications have expanded to require compliance with these standards. To ensure FCI provides unbiased failure rate data, FCI has responded to this requirement by engaging independent, authorized third parties such as exida and TÜV Nord to perform the FMEDA (Failure Mode, Effects and Diagnostic Analysis) of its thermal mass flow meter portfolio. The result is the industry’s largest offering and selection of SIL-compliant flow meters with thermal dispersion technology.

The process industry has seen many changes over the past two decades when it comes to the design and implementation of emergency shutdown/safety systems. Today, compliance with various international and regional safety standards requires a more rigorous approach to the entire safety lifecycle of a system than reliance on the best engineering design practices of the past.
