The analyzer flow switch is a small, lightweight instrument featuring low flow sensitivity and a choice of electronic outputs. Analyzer end-users or system integrators will find the unit’s advanced electronics and thermal dispersion flow sensing technology provide a superior overall solution to sampling system flow assurance. It is ideally-suited for continuous monitoring of analyzer sample flows. The analyzer flow switch’s flow sensor element has no-moving parts to foul, clog or maintain, ensuring continuous reliability and requiring virtually no maintenance, according to the manufacturer. The analyzer has no cavities, orifices or dead-legs that can trap fluids and lead to contaminated samples. The instrument’s wetted-parts are corrosion-resistant 316L stainless steel with Hastelloy-C sensor tips. The analyzer 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. The instrument fits in a standard ¼-inch tube tee or SP76 adapter (ANSI/ISA Standard 76.00.02-2002), and conforms to NeSSI Generation I and is prepped for Generation II and III compliance. Agency approvals for the FS10A Analyzer Flow Switch include FM and FMc: Non-incendive, Class I, Division 2 Groups A, B, C, D; Class II, Division 2 Groups E, F, G; Class III TA@Ta=71 degrees C Type 4X. It has also been submitted for ATEX and IEC with those approvals pending.
