Fluid Components International FS10i series compressed air flow meters

Process and manufacturing engineers responsible for compressed air systems used in a wide range of industrial applications will find the FS10i Series compressed air flow meters from Fluid Components International (FCI) can help them improve productivity by measuring accurately and quickly detecting system leaks, which can improve overall process quality while reducing system energy costs.

The compact easy-to-install units can measure the flow rate of compressed air, air and natural gas. They are accurate to ± 1.5% of reading and ±0.5% of full scale, with repeatability of ± 0.5% of reading and a response time of 4 seconds (1 time constant). They are SIL-2 rated for safety instrumented system (SIS) critical processes.

Using thermal dispersion flow sensing technology, the flow meters provide a fluid-matched, calibrated and linearised 4–20 mA output of flow rate, and a user programmable high or low flow alarm/trip point with a 1 A SPDT relay output. For visual indication, the flow meters include a 10-segment LED array. This display illuminates proportionally to the flow rate and flashes if an alarm trip occurs.

Available in both in-line and insertion style configurations to support installation in line sizes from DN25 to DN500, they operate over a 100:1 turndown from 1,6 to 122 NCMH depending on the fluid media and line size.

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.
