ST100 Mass Flow Meters
Product Overview
Fluid Components International ST100 series thermal dispersion gas flow meters combine industry leading electronics and advanced flow sensing technology to achieve a flow metering solution for a range of industrial processes and plant applications.
Whether your output needs are traditional 4-20 mA analog, frequency/pulse, 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 the ST100 Series’ Foundation Fieldbus interoperability with their systems.
