Fluid Components International has introduced the advanced FS10i Series compressed air flow meters which helps to improve productivity as well as the overall process quality. The compressed air flow meters are also capable of reducing system energy costs.

Engineers responsible for compressed air systems used in a wide range of industrial processes and plant applications will find that the advanced FS10i Series Compressed Air Flow Meters from Fluid Components International (FCI) helps them improve productivity by measuring accurately and quickly detecting system leaks, which improves overall process quality while simultaneously reducing system energy costs, shares the company.

With its compact go anywhere size, the Flow Meter Series is a dependable, economical and easy to install solution to measure the flow rate of compressed air, air and natural gas, adds the firm. These 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 ensures quick and effective installation. In addition, they are SIL-2 rated for safety instrumented system (SIS) critical processes.

The Flow Meters feature simple, easy-to-use precision direct mass flow measurement technology. They require no additional pressure or temperature sensors or other components to infer flow measurement. Their sealed and no-moving parts sensor does not foul or clog, and requires no routine maintenance that ensures years of trouble-free, continuous operation, mentions the company.

As the original developer decades ago and continuous innovator of applications-proven thermal dispersion flow sensing technology, FCI’s Flow Meters today 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.

FCI’s FS10i 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 FS10i also carries global approvals: FM, FMc, Atex, IECEx, and EAC/TR CU, and optional Div 2/Zone 2 approvals.

For 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. According to the firm, 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.

User set-up is performed using 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.

The 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, concludes the company.
