Thermal Mass Flow MeterThe ST100 Series Thermal Mass Flow Meter sets a new industry benchmark in process and plant gas flow measurement instrumentation. The ST100 combines superior flow sensing performance with the industryís most feature-rich and function-rich electronics to deliver unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow. FCI developed the advanced ST100 Series Flow Meters in response to countless hours of discussions with a wide range of instrument, process, and plant engineers who wanted more comprehensive measurement information as well as the flexibility to adapt to plant and process control technology they might deploy in the future.
Beyond its ability to continuously measure, display and transmit the most extensive array of parameters, it is the industryís first thermal mass gas flow meter designed with a migration path to tomorrow. Whether the need is for conventional 4-20 mA analog, frequency/pulse, alarm relays, or advanced digital bus communications such as HART, Foundation Fieldbus, Profibus or Modbus, the new ST100 is the solution. Should a plantís needs change over time or an upgrade be desirable, the ST100 Flow Meter adapts as necessary with a plug-in card replacement that can be changed out by plant technicians in the field.
The ST100 Flow Meterís LCD display/readout brings new meaning to the term ďprocess information.Ē The ST100ís graphical, multivariable, backlit LCD display provides the industryís most comprehensive information with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics. The ST100 measures gas mass flow rate, total flow, temperature, and pressure depending on the model family. The 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.
