Fluid Components International (FCI) developed the ST100 series thermal mass flow meter to provide the flexibility to adapt to plant and process control technology engineers might deploy in the future.
The ST100 adapts as necessary with a plug-in card replacement that can be changed out by plant technicians in the field. The meter includes a graphical, multivariable, backlit LCD display that provides continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.
The ST100 measures gas mass flow rate, total flow, temperature and pressure depending on the model family. 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. An optional, SpectraCal gas equivalency calibration method allows users select and switch between 10 common gases. Also standard is an on-board data logger with a removable 2-GB micro-SD memory card capable of storing 21 million readings.
