Accurate, zero-maintenance, long-Life CO2 flow meter offers rapid return on investment

Mar 14 2023

Fluid Components International (FCI) announces the availability of the ST100A Series Thermal Flow Meters, a rugged, no-maintenance, long-life flow meter that pays for itself in CO2 capture, storage, and utilization applications. The ST100A Series Thermal Flow Meters offer accurate CO2 gas flow measurement, essential for companies looking to take advantage of new green, clean air tax credits designed to incentivise and support the capture of CO2 in oil/gas operations, petrochemical production, and refineries. These flow meters are suitable for all-weather exposed, outdoor, Div1/Zone1 type, Hazard-Ex locations that require flow meters with rugged-duty transmitters and full agency approvals for Ex environments, and minimal maintenance to ensure uninterrupted service in difficult to access locations.

The ST100A Flow Meters provide direct mass flow measurement of CO2 in a most rugged NEMA4X/IP67 instrument with global agency Div1/Zone1 approvals of the entire instrument, and a no-moving parts technology that requires no routine maintenance to achieve maximum service life. The ST100A Series Thermal Gas Flow Meters are precision, laboratory calibrated to measure CO2 gas and dozens of other gases at the actual installation plant’s required flow rates, process temperatures, and pressure conditions. Featuring FCI’s patented AST™ thermal dispersion flow measurement technology, the ST100A Meters achieve the widest flow range with the lowest energy cost.

The ST100A Series Flow Meter measures air/gas flow from 0.25 SFPS to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale. It is available with an extensive choice of process connections, including compression fittings, fixed NPT, flanges, and packing glands. They are suitable for flow measurement in pipe sizes from 1 up to 99 inches [25mm to 2500 mm]. FCI thermal flow meters are also multi-parameter and capable of measuring both the flow and temperature of the process fluid.

The ST100A Meters offer extensive communication options capabilities. Triple 4-20 mA analogue outputs, frequency/pulse, and HART and Modbus RS485 digital bus communications are standard. Optionally, FOUNDATION Fieldbus or PROFIBUS digital I/O’s can be added. The ST100A’s optional graphical, multivariable backlit LCD display continuously displays all process measurements, alarm status, and diagnostics events for easy on-site viewing by technicians. Its “through-the-glass” activated keypad allows for set-up, instrument service diagnostics, and in-situ calibration checks without removing the instrument from the process.

ST100A Meters are third-party, independently tested and safety agency approved for hazardous environment installations. FCI products undergo rigorous agency testing and validation on the entire instrument, not just the enclosure. Approvals available for the ST100 Flow Meter include FM, FMc, ATEX, IECEx, EAC/TR CU, NEPSI, Inmetro, EQM/ECA, and is CE and UKCA Approved.
