Fluid Components International FS10i Flow Switch/Monitor

Designed for industrial processes, manufacturing operations, pumps, compressed air, gas compressors and HVAC systems requiring flow assurance and alarming, the compact SIL 2 compliant FS10i Flow Switch/Monitor from Fluid Components International (FCI) features good performance and operation.

Wherever detection and user warning of a flow rate that is either too high, too low or a no-flow condition is required, the flow switch/monitor can be used. In air, gases, water or other liquids, the flow-sensing instrument can be used for repeatable and fast-responding flow trip point or alarm warning within seconds.

The product features air/gas sensitivity and a setpoint range from 0.076 to 122 MPS, or from 0.003 to 0.15 MPS for water or liquids. It is suitable for use in fluid temperatures from -40 to 212°C and at pressures up to 138 bar, with applications including cooling water and fluids, leak detection, lubricant flow assurance, ventilation verification, chemical injection assurance, nitrogen purge verifications and compressor leak detection.

The device comes with a 1 A relay output for alarm/trip point setting, instead of an open collector, and a 4–20 mA analog output for trending and monitoring. Trip points can be set as high or low and can be adjusted with hysteresis and/or time delay settings. The 4–20 mA output is rangeable by the user in the field installation.

Developed with FCI’s no-moving-parts thermal dispersion sensing technology, the flow switch/monitor is temperature compensated for dynamic plant and process operating conditions. It is constructed of all wetted parts and manufactured with 316L stainless steel and Hastelloy C22 thermowells for years of service with virtually no maintenance.
