The Model FS10A Flow Switch/Monitor from Fluid Components International incorporates advanced electronics for continuously verifying flows within liquid or gas process analyzer sampling systems.

The flow switch is designed for use with nearly all types of process and emissions sampling systems, including gas chromatographs (GCs), mass spectrometers, optical spectrometers, photometers and others.

It fits in a standard 1/4in tube tee or SP76 adapter (ANSI/ISA Standard 76.00.02-2002, Modular Component Interfaces for Surface-Mount Fluid Distribution Components). The flow range in air is from 50cc/min to 10,000cc/min, and the flow range in water is 4cc/min to 100cc/min.

It accommodates wide turndowns with a ratio up to 100-to-1. Agency approvals for the FS10A Analyzer Flow Switch include FM and FMc: Nonincendive, Class I, Division 2 Groups A, B, C, D; Class II, Division 2 Groups E, F, G; Class III TA@Ta=71 C Type 4X. It has also been submitted for ATEX and IEC with those approvals pending.
