ST80L is a high performance, rugged thermal dispersion technology air/gas flow meter that combines ultra-reliable, feature-rich electronics with the industry's most extensive selection of application-matched flow sensors to provide a truly superior solution for industrial processes and plant applications.

The ST80 further combines these features with a robust, rugged transmitter enclosure and industry’s broadest selection of process connections to provide longest service life and ease-of-installation in your installation’s pipe or duct.

The ST80L transmitter’s outputs are a match to your DCS, PLC, SCADA, recorder, or alarm system. Whether your output needs are traditional 4-20 mA analog or advanced digital bus communications such as HART, Foundation Fieldbus, PROFIBUS, or Modbus, ST80 has you covered.
