The ST100 Series Thermal Mass Air/Gas Flow Meter 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 is said to offer 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 plantís 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.
