Fluid Components International FS10A flow switch/monitor

Click2Contact

The Model FS10A flow switch/monitor from Fluid Components International (FCI) is a low-cost solution for continuously verifying flows within liquid or gas process analyser sampling systems. It is suitable for the continuous monitoring of analyser sample flows to provide the highest integrity process analysis without interruption.

The FS10A analyser flow switch’s precision flow sensor element has no moving parts to foul, clog or maintain, ensuring continuous reliability and requiring virtually no maintenance. It has no cavities, orifices or dead-legs that can trap fluids and lead to contaminated samples, which preserves sample integrity and provides faster system sampling times. The instrument’s wetted parts are corrosion-resistant 316L stainless steel with Hastelloy-C sensor tips.

The FS10A analyser flow switch is designed for use with nearly all types of process and emissions sampling systems, including gas chromatographs, mass spectrometers, optical spectrometers, photometers and others. It fits in a standard ¼″ tube tee or SP76 adapter. SP76 is a key element of the NeSSI platform (New Sampling/Sensor Initiative) that has been evolving since 1999. The FS10A conforms to NeSSI Generation I and is prepped for Generation II and III compliance. It requires only a single 1.5 x 1.5″ SP76 base.

The FS10A analyser flow switch operates over a wide flow range, depending on the configuration selected. The flow range in air is 50 to 10,000 cc/min, and the flow range in water is 4 to 100 cc/min. It accommodates wide turndowns with a ratio up to 100:1.
