Flow Meter FCI ST100 Air/Gas Flow Meter
The ST100 Series Flow Meter combines flow sensing performance with feature- and function-rich electronics. The ST100 features a plug-in card replacement that can be changed out by technicians in the field to adapt to a plant’s changing network communication needs.
Featuring a graphical, multivariable, backlit LCD display, the ST100 Flow Meter brings new meaning to the term “process information”. Its readout continuously displays all process measurements and alarm status, and it has the ability to query for service diagnostics.
The comprehensive ST100 Flow Meter measures gas mass flow rate, total flow, temperature and pressure depending on model family. It can store up to five 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 gas equivalency calibration method, SpectraCal, lets users select and switch between 10 common gases. Also standard is an on-board data logger with an easily accessible,removable 2-GB micro-SD memory card capable of storing 21 million readings.
Triple-variable Thermal Flow Meter
The ST100 is a triple-variable thermal flow meter. Its exclusive STP family measures mass flow, temperature and pressure, while the ST family measures mass flow and temperature. Both families include single-point and dual-element models as configurations outfitted with FCI’s exclusive in-situ calibration option, VeriCal.
ST100 Series Flow Meters are available with three different types of flow sensors to best match user applications: FPC-style, FP-style and S-style. The fast-response FPC-style features an integral flow conditioner and protective shroud optimized for compressed air and clean gas applications. The FP-style is a fast response, general purpose design with a protective shroud and is also the sensor used with FCI’s VeriCal in-situ calibration option. The unshrouded S-style facilitates easy cleaning and provides a smoothed response for applications with wet or dirty gases or erratic flows.
