Full Report
The go-anywhere, rugged and reliable FS10i Flow Meter measures up when it comes to challenging, high-temperature on-site quarry lime-based carbon capture processes.
Analysis Summary
# Main Topic
The core intelligence focus is on the application and safety compliance of the **FS10i Flow Meter Series** manufactured by Fluid Components International (FCI) in demanding, high-temperature industrial environments, specifically within lime-based carbon capture processes aimed at mitigating greenhouse gases.
## Key Points
- The FS10i Flow Meter is used for precision control of natural gas burner fuel and oxygen ($\text{O}_2$) measurement within calcine furnaces during lime production, which is a precursor step in carbon capture (CC) utilizing mineral lime.
- The operational environment involves extremely high temperatures, up to $1093^\circ\text{C}$ ($2000^\circ\text{F}$), during the calcination of limestone.
- It utilizes next-generation thermal dispersion sensing technology, offering excellent repeatability ($\pm0.5\%$ of reading) and a linearized $4-20\text{ mA}$ output signal.
- The device is certified with a **Safety Integrity Level 2 (SIL-2)** rating on the calibrated $4-20\text{ mA}$ flow output and **SIL-1** compliance on the alarm relay, featuring a $90\%$ Safe Failure Fraction (SFF).
- Key physical specifications include flow sensor thermowells constructed from corrosion-resistant $\text{Hastelloy C-22}$ and an ingress protection rating of $\text{IP67}$.
- The meter has no moving parts, minimizing clogging risk and maintenance requirements compared to mechanical flow meters.
## Threat Actors
- No specific threat actors (e.g., APT groups, cybercriminals) are mentioned in the context provided. The primary focus is on operational technology (OT) reliability and industrial safety compliance.
## TTPs
- No cyber threat Techniques, Tactics, and Procedures ($\text{TTPs}$) are mentioned.
- The focus is on physical operational requirements: measuring fuel gas and $\text{O}_2$ flow rates to prevent levels from being too high or too low during calcination.
- **Physical/Safety Failure:** The device failure mode addressed is insufficient flow measurement, which could lead to inefficient heating or safety issues within the furnace process.
## Affected Systems
- **Primary System:** $\text{FS10i Flow Meter Series}$ by $\text{FCI}$.
- **Application Environment:** High-temperature, on-site quarry lime-based carbon capture processes (calcine furnaces).
- **Measured Mediums:** Natural gas fuel and Oxygen ($\text{O}_2$).
- **Installation Contexts:** DN25 ($25.4\text{ mm}$) or larger diameter pipes/square ducts, available in inline tee configurations or insertion meter lengths ($152.4\text{ mm}$ or $304.8\text{ mm}$).
## Mitigations
- **Device Hardening:** Utilization of corrosion-resistant $\text{Hastelloy C-22}$ thermowells to resist harsh operating conditions.
- **Safety Implementation:** Deployment relies on the $\text{FS10i}$'s $\text{SIL-2}$ rating for critical safety loops, ensuring a high $\text{SFF}$ against failure.
- **Maintenance Reduction:** The design inherently mitigates maintenance-related failures as it has no moving parts to clog.
- **Compliance:** The device carries multiple global industrial and hazardous environment approvals ($\text{FM, ATEX/UKEX, IECEx, CE, UKCA}$, etc.).
## Conclusion
The report details the selection of the $\text{FCI FS10i Flow Meter}$ as a robust, certified instrument essential for ensuring efficiency and safety in next-generation carbon capture infrastructure relying on high-temperature lime production. The key security (safety) takeaway is its $\text{SIL-2}$ compliance, which addresses potential process failures related to inaccurate flow measurement in critical combustion units.
