ST100 Series Gas Mass Flow Meters

The Science of Process Gas Flow Metering Advanced, Future Ready!

ST100 is an all-new, thermal dispersion technology gas flow meter that combines the most feature- and function- rich electronics with the industry's most advanced flow sensors to achieve a truly state-of-the-science flow metering solution for industrial processes and plant applications.

The ST100 series transmitter is unsurpassed in meeting your current and future need for outputs, process information and communications. Whether your output needs are traditional 4-20mA analog, frequency/pulse, alarm relays or advanced digital bus communications such as HART, Foundation fieldbus, PROFIBUS, or Modbus, ST100 has you covered. ST100's bus communications have been certified by and are registered devices with HART and Foundation fieldbus. In addition, Emerson Process (Delta V), Yokogawa, ABB (800xA Foundation Fieldbus) and ABB (800xA HART) have tested and verified ST100 Series' Foundation Fieldbus interoperability with their systems. What's more, should you ever need to change or upgrade, ST100 can be converted to any of these outputs with a simple card change, in the field. Now that's taking never obsolete to a whole new level!

Then there's ST100's display/readout, which brings new meaning to the term process information. Simply, the ST100's graphical display provides the most comprehensive information on the process measurements and conditions of any thermal flow meter available---see the ST100 close-up page for all the details.

To complete the solution, ST100 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 ST100. And, 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 ST100 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, ST100 offers a comprehensive selection of process connections and installation options.
