Flow Meter Obtains Full HART Certification

The breakthrough ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (USA) has obtained full certification from the HART Foundation for its hardware and DD files, indicating full compliance with the HART Communication Protocol. 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.

The future-ready ST100 Series Flow Meter offers the most feature-rich and function-rich electronics on the market 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 wastewater plant’s needs change over time or an upgrade be desirable, ST100 Flow Meters adapt as necessary with a plug-in card replacement that can be changed out by field plant technicians.

Highly user-friendly, the ST100 stores up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown.

Designed for rugged wastewater plants, ST100 Flow Meters include service up to 850ºF (454ºC) and are available with both integral and remote (up to 1000 feet [300 meters]) electronics versions.
