FCI: Air/Gas Mass Flow Meter with Dual Averaging

Oct. 11, 2013
The ST102A offers higher accuracy for large pipes and ducts.

The flowmeter features a dual-element averaging system that improves installation repeatability and accuracy for larger diameter pipes and ducts. Averaging the outputs of two sensing elements minimizes errors caused by distorted, swirling and non-repeatable flow profiles. Each flow element can be independently configured for insertion length and process connection to allow installation flexibility. One can be integral with the flow transmitter, or both can be configured as remote for easier access and visibility to the digital display/optical four-button user interface. The unit also provides independent information for each flow element, saving time when performing service checks. Other features include a graphical, multivariable, backlit LCD display/readout, storage of up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and 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. Transmitter are suitable for service up to 850 ºF (454 ºC) and are available with both integral and remote (up to 1000 feet [300 meters]) electronics versions. The unit is agency approved for hazardous environments, including the entire instrument, the transmitter and the NEMA 4X/IP67 rated enclosure. Instrument approvals include FM, FMc, ATEX, IECEx, InMetro, GOST, and NEPSI.
