Continuous Flow Verification

With FM and FMc approvals, the FS10A Analyzer Flow Switch/Monitor from Fluid Components is suitable for continuous flow verification applications that support process analyzer sampling systems operating in hazardous plant areas in the United States (U.S.), Canada and elsewhere worldwide. The FM and FMc 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. It is a small, lightweight instrument featuring low flow sensitivity, a relay alarm trip point, an analog output and an RS232 interface. The device's electronics and thermal dispersion flow sensing technology provide a superior overall solution to sampling system flow assurance. It is suited for continuous monitoring of analyzer sample flows to provide the highest integrity process analysis without interruption.
