FCI FS10A Analyzer Flow Switch/Monitor

Click2Contact

In a range of industries, the close control of toxic and/or combustible gases requires the continuous monitoring of analysers to ensure their safe, effective use to protect employees and assure product quality. Fluid Components International’s FS10A Analyzer Flow Switch/Monitor is a sophisticated universal flow switch and monitor specifically designed for gas and liquid process analyser sampling systems.

Utilising FCI’s thermal dispersion flow measurement technology, the device is designed with proprietary equal mass sensing to achieve good sensitivity and repeatability. The instrument’s wetted parts are corrosion-resistant 316L stainless steel with Hastelloy C-22 sensor tips. The sensor element has no moving parts to foul, clog or maintain. There are no cavities, orifices or dead-legs to trap or contaminate samples, which preserves sample integrity and enables fast sampling times.

The instrument’s remote configuration is Div 1/Zone 1 FM approved for hazardous environments. The remote configuration is useful when the sensor’s installation area is subjected to high temperatures or for mounting directly to the front panel of the analyser, placing its display in a more convenient location for technician viewing.

The fast-responding, repeatable device is designed with an easy-to-read, top-mounted, flow rate monitoring LED array for at-a-glance visual indication of operational status of proper flow rate to the analyser or sampling system, or that an alarm/trip point has occurred. The flow switch’s set-point is user-settable via two push-buttons accessible at the top of the unit or via the RS232C I/O port.

The product is suitable for use with nearly all types of process and emissions sampling systems, including gas chromatographs (GCs), mass spectrometers, optical spectrometers, photometers and others. Standard configurations will accommodate standard 1/8″, 1/4″, 3/8″ and 1/2″ tubing as well as the SP76 (NeSSi) modular manifold. In addition to its SIL-2 rating, the product features global hazardous area operations approvals including ATEX, CE, CRN, EAC/TR CU, FM, FMc and IECEx for use in Div 2/Zone 2 environments.
