FCI earns agency approvals for FS10i flow switch/monitor

May 25, 2017—Designed for operation in rugged industrial processes, the FS10i Flow Switch/Monitor from Fluid Components International (FCI)  has obtained hazardous area approvals from multiple agencies for a range of liquid or gas monitoring applications that require accurate, reliable flow assurance and alarming.

FCI’s FS10i Flow Switch/Monitor has obtained agency approvals that include:  FM and FMc for nonincendive, Class I, Division 2, Groups A,B, C, D;  Class II, Division 2 Groups E, F, G; Class III, [email protected]=71°C; ATEX, IECx nonincendive for gas and dust, Zone 2; EAC (TRCU) Russia, II 3 G Ex nA IIC T4 Gc, II 3 D Ex tc IIIC T81°C Dc, IP64

Ingress protection meets IP65, IP66, IP67 in non-hazardous locations; CE Marking, CRN, complies with Canadian Electrical code requirements of ANSI/ISA 12.27.01-2011 as a single seal device.  It is also the only product in its class to carry a SIL 2 compliance rating per IEC 61508 and has a superior 90% Safe Failure Fraction (SFF). 

In air, gases, water or other liquids, the FS10i Flow Switch/Monitor is the solution wherever detection and user warning is required for a flow rate that is either too high, too low or a no-flow condition is present. Its SIL-2 compliance also ensures a highly reliable flow sensing instrument for repeatable and fast-responding flow trip point or alarm warning within seconds.  

The FS10i Flow Switch/Monitor features an air/gas sensitivity and setpoint range from 0.25 to 400 SFPS [0.076 to 122 MPS] and for water or liquids from 0.01 to 0.5 FPS [0.003 to 0.15 MPS]. It is suitable for use in fluid temperatures from -40° to 250°F [-40° to 212°C] and at pressures up to 2000 psi [138 bar].   Different than other devices, the FS10i Flow/Switch Monitor comes standard with both an SPDT 1A 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 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. 

Designed for application versatility, the FS10i Flow Switch/Monitor is designed for monitoring 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 no-moving parts thermal dispersion sensing technology, the FS10i Flow Switch/Monitor is temperature compensated for plant and process operating conditions.  It is constructed of all wetted parts manufactured with 316L stainless steel and Hastelloy C22 thermowells.

The FS10i Flow Switch/Monitor electronics are enclosed in a stainless steel body housing with aluminum end cap/top with polycarbonate overlay, which carries an IP66/IP67 rating.   Input power is 24 Vdc (21.5 to 30 Vdc); 2.5 Watts maximum.

The FS10i Flow Switch/Monitor is available in two probe lengths (insertion depth): a 2 -inch [50 mm] length with a 0.25-inch NPT (M); and a 6 inch [150 mm] length, variable depth, with 0.5-inch NPT (M) compression fitting, with either a Teflon or metal ferrule.  Electrical connections are to a standard M12 connector or, optionally, to 15 ft [3m] cable with pigtail terminations.
