The ST100 series thermal mass air/gas flow meter from Fluid Components International (FCI) has received ATEX and IECEx approval. The approvals certify that the flow meter has been designed and tested for safe operation in potentially hazardous environments.

In addition, the flow meter’s enclosure is ATEX and IECEx certified as flame-proof and protected from dust ignition. These approvals specify design criteria for flow meters and other electrically powered instruments for use in areas where combustible gases may be present.

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, patent-pending SpectraCal gas equivalency calibration method lets 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.
