Production and refinery engineers responsible for measuring, monitoring and flaring waste gas will find the advanced ST100 Series thermal mass flow meter from Fluid Components International (FCI), with FCI’s VeriCal™ In-Situ calibration verification system, combines precise air/gas measurement capability with the convenience of in-situ calibration verification.

The ST100 flow meter with the VeriCal In-Situ calibration system is designed to comply with the US Minerals Management Service (MMS) mandate per final rule, 30 CFR Part 250, Subpart K, Section 250, stipulating that all domestic US offshore rigs processing more than an average of 2,000 BBl/d of oil must install flare/vent gas flow meters, and is intended to protect the environment through the monitoring of greenhouse gases,

Validating flow meter calibration to meet regulatory requirements is no longer labour-intensive, costly or challenging with the VeriCal In-Situ calibration system, which verifies flow meter calibration in minutes without removing the meter from the pipe or process. In the past, flow meters had to endure the cost and hassle of being pulled from the process, then returned to the manufacturer or a calibration lab for testing and then shipped back for re-installation.

The ST100 series flow meter sets a new industry benchmark in process and plant air/gas flow measurement, offering the most feature-rich and function-rich electronics available. The ST100’s performance delivers unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow.

The ST100 flow meter’s unique graphical, multivariable, backlit LCD display/readout also provides the industry’s most 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 1,000:1 turndown. Also standard is an on-board data logger with an easily accessible, removable 2GB micro-SD memory card capable of storing 21 million readings.

The comprehensive ST100 Series is composed of two core model families: ST and STP. ST meters measure both mass flow and temperature, and the exclusive STP family adds a third parameter, pressure, making the ST100 the world’s first triple-variable thermal flow meter. Both families include single-point and dual-element models as configurations.

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 with accuracy of
±0.75 per cent of reading, ±0.5 per cent of full scale.

Designed for rugged industrial processes and plants, ST100 flow meters include service up to 454º C and are available with both integral and remote 300 m electronic versions. The ST100 is agency approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67-rated enclosure. Instrument approvals in addition to SIL-1 include ATEX, IECEx, FM and FMc.
