The Model FS10A Analyzer Flow Switch/Monitor from Fluid Components International (FCI) has received both FM and FMc (Canadian) approvals.

FCI claims that this will be of particular interest to engineers in search of a low-cost flow verification solution for process analyzer sampling systems that is suitable for hazardous plant environments.

With FM and FMc approvals, the FS10A is suitable for continuous flow verification applications that support process analyzer sampling systems operating in hazardous plant areas in the US, Canada and elsewhere worldwide.

The approvals are as follows: Nonincendive, Class I, Division 2 Groups A, B, C, D; Class II, Division 2 Groups E, F, G; Class III T4@Ta=71ºC Type 4X.

The FM and FMc approvals specify design criteria for flow meters and other electrically-powered instruments for use in areas where combustible gases may be present.  These approvals assure the instrument has been designed and tested to operate safely in these hazardous conditions.

According to FCI, the Model FS10A represents the next-generation, lowest-cost solution for continuously verifying flows within liquid or gas process analyzer sampling systems. Small and lightweight, the instrument features superior low flow sensitivity, a relay alarm trip point, an analog output, and an RS232 interface. Its advanced electronics and thermal dispersion flow sensing technology provide a superior overall solution to sampling system flow assurance.

The breakthrough FS10A Analyzer Flow Switch/Monitor features a precision flow sensor element with no moving parts to foul, clog or maintain, ensuring continuous reliability and requiring virtually no maintenance. It 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. Standard configurations will accommodate 1/8, ¼, 3/8 and ½ inch sampling tubes as well as an SP76 adapter (ANSI/ISA Standard 76.00.02-2002, Modular Component Interfaces for Surface-Mount Fluid Distribution Components).
