The ST100A series transmitter is unsurpassed in meeting your current and future need for outputs, process information and communications. Whether your output needs are traditional 4-20 mA analogue, frequency/pulse, or advanced digital bus communications such as HART, Foundation fieldbus, PROFIBUS, or Modbus, ST100A has you covered. ST100A’s bus communications have been certified by and are registered devices with HART and Foundation Fieldbus. In addition, Emerson Process (Delta V), Yokogawa and ABB (800xA) (see page 6) have tested and verified ST100A Series’ Foundation Fieldbus interoperability with their systems.

Then there’s ST100A’s display/readout, which brings new meaning to the term process information. Simply, the ST100A’s graphical display provides the most comprehensive information on the process measurements and conditions of any thermal flow meter available – see the ST100A close-up page for all the details.

To complete the solution, ST100A flow elements and process connections ensure the best possible measurements and effective installation. FCI flow element designs have been perfected and optimized through six decades of R&D and real-world experience in thermal dispersion technology and flow metering applications. With thermal dispersion there are no moving parts to foul or clog. This results in the greatest reliability and valuable savings on maintenance.

Fast response, accuracy, repeatability and long-life are hallmarks of FCI flow elements available with ST100A. All new are the STP models, which add pressure measurement. Mass flow, temperature, and pressure in a single tap-point thermal dispersion meter… An industry first and FCI exclusive! Then, consider other ST100A Series exclusives like dual-element measuring systems and FCI’s patented VeriCal option that provides significant cost and time savings by performing dynamic calibration verification in-situ, without ever removing the instrument from the process. To ensure both ease of installation and a match with your process conditions, ST100A offers a comprehensive selection of process connections and installation options.
