FCI's ST100 Aeration Flowmeter
The ST100 Thermal Mass Flowmeter provides accuracy combined with digital bus communication flexibility to reduce air flow energy costs. Whether the need is for Profibus, Fieldbus, HART, or Modbus, 4-20 mA analog, frequency/pulse, or alarm relays, the ST100 Flow meter is the versatile communication solution. If a plant’s communication needs change, the ST100 meter adapts with a plug-in card replacement that can be changed out in the field. The ST100 Flow Meter’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. Also standard is an on-board data logger with an easily accessible, removable 2-GB micro-SD memory card capable of storing 21 million readings. The ST100 can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.07 NMPS to 305 NMPS (0.25 to 1000 SFPS) with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale.
