New SIL 2 compliant flow switch/monitor for a wide application range
Fluid Components International (FCI), a global flow sensing and measurement company, has introduced a new SIL2 compliant flow switch/monitor for a wide range of processing and production applications.
Designed for industrial processes, manufacturing operations, pumps, compressed air, gas compressors, and HVAC systems requiring flow assurance and alarming, the new FS10i flow switch/monitor is capable of providing high performance and reliable operation.
The FS10i features water or liquids sensitivity and setpoint range from 0.003 to 0.15m/s and for air/gas from 0.076 to 122m/s, and it is suitable for use in fluid temperatures from -40° to 212°C and at pressures up to 138 bar.
Unlike similar devices, the FS10i comes standard with both a 1A relay output for alarm/trip point setting instead of an open collector, and a 4-20mA analogue output for trending and monitoring.
Trip points can be set as high or low, and they can be adjusted with hysteresis and/or time delay settings and the 4-20mA output is rangeable by the user in the field installation.
The device is well suited for manufacturing plants, chemical, refining, power Generation, food and beverage, metals processing, mining, and water and wastewater industries.
Applications for the switch/monitor include cooling water and fluids, leak detection, lubricant flow assurance, ventilation verification, chemical injection assurance, nitrogen purge verifications, and compressor leak detection.
Developed with FCI’s advanced no-moving parts thermal dispersion sensing technology, the FS10i is temperature compensated for dynamic plant and process operating conditions.
It is constructed of all wetted parts manufactured with 316L stainless steel and Hastelloy C22 thermowells for years of service with virtually no maintenance.
The insertion style FS10i is easy to install, and set-up is done in the field using either a two-button keypad or with a PC connection to the FS10i’s serial I/O port.
The instrument features a 10-character LED array to indicate actual flow range and, when trip point is reached, the LED will begin to flash to provide an immediate visual indication to the user.
For long service life, the device’s electronics are enclosed in a stainless steel body housing with aluminum end cap/top with polycarbonate overlay, which carries an IP66/IP67 rating.
The flow switch/monitor is the only product in its class to carry a SIL 2 compliance rating and has a 90% Safe Failure Fraction (SFF).
The FS10i is available in a choice of three different probe length (insertion depth) and process connection combinations, a 2” length with a 0.25” NPT (M) and a 6” length, variable depth, with 0.5” NPT (M) compression fitting, with either a Teflon or metal ferrule.
Electrical connections are to a standard M12 connector or, optionally, to 3m cable with pigtail terminations.
