Flow Switch/Monitor Receives Zone 2 Approvals

Engineers in search of a low-cost flow verification solution for process analyser sampling systems that is suitable for hazardous plant environments will be pleased to learn that the advanced Model FS10A Flow Switch/Monitor from Fluid Components International (FCI), USA, has received ATEX and IECEx approvals.

With ATEX and IECEx approvals, the FS10A Flow Switch/Monitor is suitable for continuous flow verification applications supporting process analyser sampling systems operating in hazardous plant areas in the European Community and elsewhere worldwide. The ATEX and IEC 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.

The Model FS10A Flow Switch/Monitor represents the next-generation, lowest-cost solution for continuously verifying flows within liquid or gas process analyser sampling systems. It is a small, lightweight instrument featuring superior low flow sensitivity, a relay alarm trip point, an analog output and an RS232 interface. The FS10A’s advanced electronics and thermal dispersion flow sensing technology provide a superior overall solution to sampling system flow assurance. It is ideally suited for continuous monitoring of analyser sample flows to provide the highest integrity process analysis without interruption.

The breakthrough FS10A Analyser Flow Switch features a precision flow sensor element with no moving parts to foul, clog or maintain, ensuring continuous reliability and requiring virtually no maintenance. Unlike capillary bypass flow meters and controllers, 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.
