FS10A Analyzer Flow Switch/Monitor

Process or analytical instrumentation engineers looking for a flow verification solution for their process analyzer sampling systems, the Model FS10A Analyzer Flow Switch/Monitor from Fluid Components International (FCI) meets the requirements for Safety Integrity Level (SIL) 2 compliant service.

FCI’s SIL 2 compliance rating for the FS10A Analyzer Flow Switch/Monitor has been documented in a failure analysis report with FMEDA techniques by the accredited certification body exida.  The FS10A has been classified as a Type B subsystem in accordance to IEC 61508-1 with a hardware failure tolerance of 0.  

The product 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 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. 

The FS10A Analyzer Flow Switch/Monitor outputs include a 1A relay settable for NO or NC operation and with user-settable for failsafe, hysteresis and/or time delay, and a 4-20mA analog output for trending. In addition to SIL 2 compliance, agency approvals for the FS10A Analyzer Flow Switch/Monitor include FM, FMc, ATEX and IECEx for hazardous location installations.

    ST100

    ST100

    The ST100 Series Flow Meter sets a new industry benchmark in process and plant air/gas flow measurement, delivering unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow.

    The ST100 Flow Meter’s graphical, multivariable, backlit LCD display/readout brings new meaning to the term “process information”. It provides the industry’s most comprehensive information with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.

    The user-friendly ST100 stores up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown.  An optional, patent-pending SpectraCal Gas Equivalency calibration method lets users select and switch between 10 common gases. An on-board data logger with an easily accessible, removable 2-GB micro-SD memory card capable of storing 21 million readings comes standard.

    The ST100 offers three different types of flow sensors to best match user applications.  The fast-response FPC-style is a fast response features an integral flow conditioner and protective shroud optimized for compressed air and clean gas applications. The fast-response, general purpose FP-style features a protective shroud and is the sensor used with FCI’s VeriCal in-situ calibration option.  For wet or dirty gases, or erratic flows, the unshrouded S-style facilitates easy cleaning and provides a smoothed response.

    The ST100 can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases.  The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.25 to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of  ±0.75 percent of reading, ±0.5 percent of full scale.  

    Designed for rugged industrial processes and plants, ST100 Flow Meters include service up to 850ºF and are available with both integral and remote (up to 1000 feet) electronics versions. The ST100 is agency approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67 rated enclosure.  Instrument approvals in addition to ATEX and IECEx include FM and FMc.
