Fluid Components International’s FS10i Series compressed air flow meter is SIL-2 rated and helps to cut compressed air cost along with maintenance needs. The flow meter is ideally used in systems for blowing, bottling, cleaning, coating, conveying, cooling, molding, paint spray booths, packaging, pneumatic tooling, and wrapping.

Engineers responsible for operating industrial process compressed air systems will find that the reliable FS10i Series Compressed Air Flow Meter from Fluid Components International (FCI) helps them cut system usage cost, improve productivity and reduce maintenance cycles all at the same time, shares the company.

The compact Flow Meter Series is a dependable, easy-to-install solution to measure the flow of air, compressed air or natural gas. These Flow Meters are accurate to ±1.5 % of reading, ±0.5 % of full scale, with repeatability of ±0.5 % of reading and have a response time of 4 seconds (1 time constant). Their small size, plug-in wiring and inline or insertion style threaded connection into plant piping enables quick and effective installation. In addition, they are SIL-2 rated for safety instrumented system (SIS) critical processes, adds the firm.

FCI’s advanced FS10i Flow Meters feature direct mass flow measurement technology. They require no additional pressure or temperature sensors or other components to infer flow measurement. Their sealed, no-moving-parts sensor does not foul or clog, and it requires no routine maintenance, ensuring years of trouble-free, continuous operation, mentions the company.

The Flow Meters provide a fluid-matched, calibrated and linearized 4-20mA output of flow rate, along with a user-programmable high or low flow alarm/trip point with a 1A SPDT relay output. For visual indication, the FS10i Flow Meters include a 10-segment LED array. This display illuminates proportionally to the flow rate and flashes if an alarm trip occurs.

These small, go-anywhere flow meters are available in both in-line and insertion-style configurations to support installation in line sizes from 1 inch to 20 inches [DN25 to DN500]. They operate over a wide, 100:1 turndown from 1 to 400 SCFM (1,6 to 122 NCMH) depending on the fluid media and line size.

Their 316L stainless steel construction ensures superior corrosion resistance in the pipe. An aluminum housing and protective rubber boot surrounding the display area make the FS10i suitable for IP64 installations. The Flow Meter also carries global approvals: FM, Fmc, Atex, Iecex, and EAC/TR CU, and optional Div 2/Zone 2 approvals, opines the company.

For smaller line sizes of 1 or 2 inches (DN25 or DN50), the FS10i is built as an in-line solution with a stainless steel, female NPT pipe tee to ensure the instrument’s accuracy and repeatability in the installation. For line sizes 2.5 inches (63,5 mm) or larger, users can select the insertion-style configuration in either a 6 or 12 inch (152 or 305 mm) length. The insertion-style configurations are outfitted with a 0.5-inch compression fitting, with either a Teflon or stainless steel ferrule to adjust the actual insertion depth to be compatible with a range of pipe diameters and achieve inserting the sensor element to the center-point of the pipe.

Set-up is simplified with a PC connection to the instrument’s serial port, included computer interface dongle and using FCI’s free software utility program. User set-up functions include scaling of the 4-20 mA output to the desired flow range and engineering units, setting the relay trip point and adding hysteresis or time delay to the relay’s action, etc.

FCI’s FS10i Flow Meters are manufactured in the USA at FCI’s Southern California operations. Each meter is precision calibrated on FCl’s air and gas flow stands, which are outfitted with Nist and ISO/IEC 17025 traceable equipment to ensure their accuracy and measurement repeatability, mentions the firm.
