Fluid Components International (FCI) Model FS10A Flow Switch/Monitor

With a space-saving design incorporating advanced electronics, the Model FS10A Flow Switch/Monitor from Fluid Components International (FCI) is used for continuously verifying flows within liquid or gas process analyser sampling systems.

The flow switch is a small, lightweight instrument featuring good low-flow sensitivity, a choice of electronic outputs and a no-moving-parts design to ensure reliability. Analyser end users or system integrators will find the unit’s advanced electronics and thermal dispersion flow sensing technology provide a good overall solution to sampling system flow assurance.

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 ¼″ tube tee or SP76 adapter (ANSI/ISA Standard 76.00.02-2002, Modular Component Interfaces for Surface-Mount Fluid Distribution Components). 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 unit operates over a wide flow range - in air it is from 50 to 10,000 cc/min and in water it is 4 to 100 cc/min. It accommodates wide turndowns with a ratio up to 100:1.

The unit’s electronics are packaged in a fully sealed aluminium housing. The electronics can be integral mounted with the sensor element in a uni-body configuration or remotely mounted for easy front panel display viewing. It features a top-mounted, 10-LED array and two pressure-sensitive button touch controls. The LED display provides flow rate trend, alarm status and power on/off.
