Flow Switch/Monitor Receives FM Div 1/Zone 1 Approval
The FS10A Analyzer Flow Switch/Monitor from Fluid Components International (FCI) has received FM Div 1/Zone 1 Approval on all remote probe configurations. The Div 1/Zone 1 Approval indicates that they have been certified for hazards that are present under normal operating conditions or present frequently under maintenance or repair operations. The unit is suited for continuously verifying flows within liquid or gas process analyzer sampling systems.
The FS10A Analyzer Flow Switch/Monitor ensures continuous reliability and requires virtually no maintenance, featuring a precision flow sensor element with no moving parts to foul, clog or maintain. Unlike alternative technologies, such as magnetic floats, capillary bypass or rotameters, the FS10A 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-C22 sensor tips.
The FS10A Analyzer Flow Switch/Monitor is ideal 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 inch tubing as well as an SP76 adapter (ANSI/ISA Standard 76.00.02-2002, Modular Component Interfaces for Surface-Mount Fluid Distribution Components). The SP76 adapter is a key element of the NeSSITM platform (New Sampling/Sensor Initiative). The FS10A conforms to NeSSI Generation I and is prepped for Generation II and III compliance, requiring only a single 1.5-x-1.5-inch SP76 base.
Depending on the tube size, the FS10A Analyzer Flow Switch/Monitor operates over a wide flow range in air/gas; from 0.02 SCFH to 200 SCFH (10 cc/min to 100,000 cc/min), and in water/liquids; from 0.0.01 GPH to 12.00 GPH (0.70 cc/min to 750.00 cc/min). It accommodates wide turndowns with a ratio up to 100:1.
