July 1, 2012 - The ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) has obtained full certification from the HART Foundation for its hardware and DD files, indicating full compliance with the HART Communication Protocol. The certification and DD file are available for download from the HART Foundation web site. The field-proven, easy-to-use HART Communication Protocol represents the global standard for instrumentation communications, providing reliable two-way digital communication between intelligent field instruments and host systems without disturbing the integrity of the 4-20mA analog signal. HART communications permit remote process variable interrogation, cyclical access to process data, parameter setting and diagnostics.
Unlike other technologies, HART provides a unique communication solution that is backward compatible with the installed base of instrumentation in use today. In addition to the HART Communication Protocol, the ST100 is available with 4-20 mA analog, frequency/pulse, alarm relays and additional digital bus communications including Fieldbus, Profibus and Modbus. Should a plant’s needs change over time or an upgrade be desirable, the ST100 Flow Meter adapts as necessary with a plug-in card replacement that can be changed out by plant technicians in the field. That takes “never obsolete” to a whole new level in flow measurement instrumentation.
