FCI FS10i series compressed air flow meters

Click2Contact

The compact FS10i flow meter series is an easy-to-install solution to 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 s (one time constant). Their go-anywhere 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.

Providing precision direct mass flow measurement, the flow meters 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, for years of trouble-free, continuous operation.

Utilising decades-long, applications-proven thermal dispersion flow-sensing technology, the FS10i 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.

The flow meters are available in both inline and insertion style configurations to support installation in line sizes from DN25 to DN500. They operate over a wide, 100:1 turndown from 1.6 to 122 NCMH depending on the fluid media and line size.
