Plant Safety Range of SIL-Rated Thermal Flow Meters for Safety Critical Applications
The Fluid Components International (FCI) claims to offer the industry’s broadest selection of SIL-rated thermal mass air/gas flow meters. The products are also approved by global agencies for Ex-rated installations and can be used across chemical plants, power plants, refineries, oil/gas, mining, cement, etc.
Process and plant engineers in demanding industries who are responsible for safety-instrumented systems (SIS) requiring air/gas flow measurement will find that Fluid Components International (FCI) offers them the industry’s broadest selection of SIL-rated thermal mass air/gas flow meters, states the company.
For the last 10-plus years, the firm has invested in developing SIL compliant products across its product line and today offers more SIL rated thermal mass flow meters than any other manufacturer, adds the company. From basic air to the complex gas mixture gas flows and from common 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 flow meter solution, opines the firm. In addition to SIL ratings, the products are approved by global agencies for Ex-rated installations.
The international standards most often cited and requested for SIS in industrial processes and applied to thermal flow meters are: IEC 61511: Functional Safety - Safety Instrumented Systems for the Process Industry Sector; ANSI/ISA-84.00.01 (IEC 61511 Mod) - Functional Safety: Safety Instrumented Systems for the Process Industry Sector; and IEC 61508: Functional Safety of Electrical, Electronic, & Programmable Electronic Safety Related Systems.
With an ever-increasing demand and global focus on plant and operational safety within the chemical, electric power, oil/gas, petroleum refining and other industries, instrumentation specifications have expanded to require compliance with these standards. To ensure that the company provides unbiased failure rate data, FCI has responded to this requirement by utilizing independent, authorized third parties such as exida and TÜV Nord to perform the FMEDA (Failure Modes, Effects and Diagnostics Analysis) of its portfolio of thermal mass flow meters. The result is the industry’s largest offering and widest selection of SIL compliant thermal dispersion technology flow meters, mentions the firm.
