Fluid Components FS10A Analyser Flow Switch/Monitor

Process or analytical instrumentation engineers looking for a flow-verification solution for their process analyser sampling systems, and specifically when it is part of a safety instrumented system (SIS) process will be interested to learn that the Model FS10A Analyser Flow Switch/Monitor from Fluid Components meets the requirements for SIL 2 compliant service.

The SIL 2 compliance rating for the device has been documented in a failure-analysis report with FMEDA techniques by the accredited certification body exida. The unit has been classified as a Type B subsystem in accordance to IEC 61508-1 with a hardware failure tolerance of 0. The average probability of failure on demand (PFD) and safe failure fraction (SFF) meets the requirements for SIL 2 compliance set forth in the standards.

The unit provides a solution for continuously verifying flows within liquid or gas process analyser sampling systems. It is a small, lightweight instrument featuring good low-flow sensitivity, a relay alarm trip point, an analog output and an RS232 interface. Its advanced electronics and thermal dispersion flow-sensing technology provide an accurate, repeatable overall solution for sampling system-flow assurance.
