FCI ST75 series flow meter

Engineers monitoring natural gas compressors for dry seal leaks of toxic, combustible methane (CH4) gas will find the ST75 series thermal mass flow meter from Fluid Components International (FCI) provides them with CH4 gas monitoring to detect hazardous, non-compliant and costly gas leaks. The compact air/gas flow meters offer repeatable CH4 measurement to meet environmental regulations, making them useful for crowded equipment areas where gas monitoring and measurement are essential.

The meter senses slight changes in flow, making it suitable for detecting fugitive methane emissions. It is also suitable for small line, low flow measurements in the oil and gas industry’s production, processing, transportation and storage segments. It measures air or gases from 0.01 to 950 NCMH depending on line size and actual process conditions. The meter is factory calibrated and can provide a flow turndown range up to 100:1.

With built-in temperature compensation, the flow meter offers repeatable performance in harsh industrial process environments. It features accuracy to ±2% of reading with ±0.5% repeatability over varying process temperatures and pressures in line sizes from 6 to 51 mm. With an integral Vortab Flow Conditioner, the Models ST75V or ST75AV are suitable for installations with limited straight-run and/or for operating in the Reynolds number transitional flow range with accuracy of ±1% reading, ±0.5% full scale.

The versatile instrument is suitable for mixed or single process gases depending on the application and is calibrated to NIST laboratory standards. It features remote mounting for crowded hazardous areas or where the measurement point is not easily accessed. The remote mount transmitter, which has an option for local indication of flow, temperature and totalised flow, can be mounted up to 15 m from the flow sensor in the process piping and has two 0.50″ FNPT or M20 conduit connections for power and output wiring.

Offering high performance, the ST75 or ST75A flow meter eliminates the need for additional pressure and temperature sensors, flow computers or other devices. It also requires virtually no maintenance. It is enclosed in an industrial-grade, all-metal, dust- and water-resistant NEMA Type 4X (IP66) rated package designed for Class 1, Div 1/Div 2 hazardous area installations and includes a robust, all-welded sensing element constructed with 316 stainless steel and Hastelloy-C tips.
