AMS Instrumentation and Calibration announces that the future-ready ST100 Series thermal mass air/gas flow meter from Fluid Components International (FCI) is now rated for Safety Integrity Level (SIL) 1 compliant service.
The SIL-1 compliance for the ST100 will help process and plant engineers seeking a next-generation air/gas flow meter suitable for critical operations and hazardous environments. SIL ratings provide a key assurance of confidence that safety rated equipment has been tested and shown to prevent dangerous failures and to control them in the event they occur.
FCI’s SIL compliance rating for the ST100 flow meters has been documented in a failure analysis report with FMEDA techniques by Exida, an accredited global functional safety certification company. The ST100 flow meter is classified as a Type B subsystem in accordance with IEC 61508-1 with a hardware failure tolerance of 0. The Probability of Failure on Demand (PFD) meets SIL-1 capability standards.
The ST100 Series flow meter sets a new industry benchmark in process and plant air/gas flow measurement, offering feature-rich and function-rich electronics. The ST100’s performance delivers excellent adaptability and value to meet plant gas flow measurement applications for today and tomorrow.
Whether the need is for 4-20 mA analogue, frequency/pulse, alarm relays or digital bus communications such as HART, Fieldbus, Profibus or Modbus, the ST100 is the solution. FCI’s ST100 flow meters adapt to the changing needs of a plant with a simple plug-in card replacement that can be changed out by plant technicians in the field.
The ST100’s unique graphical, multivariable, backlit LCD display/readout provides comprehensive information with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.
The user-friendly 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. A standard on-board data logger comes with an easily accessible, removable 2GB micro-SD memory card capable of storing 21 million readings.
FCI’s ST100 flowmeters offer three different types of flow sensors to best match user applications, and comprise of two core model families: ST and STP. While ST flow meters measure both mass flow and temperature, the exclusive STP family adds a third parameter - pressure.
The ST100 can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. Designed for rugged industrial processes and plants, ST100 flow meters include service up to 454°C and are available with both integral and remote electronics versions. The ST100 is agency approved for hazardous environments including the entire instrument, the transmitter and the rugged NEMA 4X/IP67 rated enclosure. Instrument approvals in addition to SIL-1 include ATEX, IECEx, FM and FMc.
