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 4-20 mA 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 and ABB (800xA) 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!
