FCI mass flowmeters receive ATEX
approval
With their intelligent microprocessor-based no-moving part thermal mass flow sensors for high accuracy gas flow measurement, the FCI mass flowmeters have now received ATEX approval to EExd IICT4
These new ATEX-approved GF90 and GF92 Mass Flow Meters are air/gas flow meters that have been designed to isolate their electronics from the danger of explosive hydrocarbon gases and other dangerous gases The ATEX directive requires flowmeters and other electrically-powered instruments and control devices meet specific design criteria to prevent explosions and fires in the presence of combustible gases

Thermal mass flowmeter for hazardous areas
The new ST50 flowmeter delivers exceptional performance, installation versatility and economy in air, compressed air or nitrogen and a variety of other processes gases, as well as plant HVAC systems
The GF90 and GF92 flowmeters are designed with a precision thermal mass gas flow sensing element manufactured with 316 stainless steel and nickel-braze construction for superior performance in rugged environments.
They feature turndowns of 1000:1, repeatability of +0.5 percent of reading or better and a flow rate accuracy of +1 percent of reading plus 0.5 percent full scale.
The GF90 and GF92 were developed for complex multi-gas or variable flow processes with an advanced microprocessor-based programmable transmitter.

Flow and liquid level interface switch is SIL2
Built to comply with process industry precision requirements for flow, level and interface sensing in liquid, gas or foam, the innovative FLT93 Switch Series is now rated SIL2 compliant
The GF Series transmitter can store up to three calibration groups.
Each group can be independently configured for a specific calibration range, fluid, switch point settings, to provide accuracy in complicated gas processes.
These instruments are also inherently multi-variable, providing both flow and temperature measurements without any additional tap points.
The GF90 and GF92 each come with a standard NEMA Type 4X (IP66) rated transmitter enclosure, with configuration options for local or remote mount application.
Optional Class I and II, Division 1 and 2, Groups B, C, D, E, F and G [EEx d IIC] transmitter enclosures are also available with agency approvals for FM, CSA and ATEX.
GF90 Insertion Flow Meter.
The GF90 is a heavy-duty industrial flow meter designed for applications that include: flare gas, combustion air to boilers, scrubber balancing, exhaust stacks and more.
It is suitable for use in ducts or pipes with a minimum 2-inch (50 mm) nominal inside diameter.
Flow sensitivity ranges from 0.25 to 1600 SFPS (0.08 to 488 NMPS) at a standard temperature of 70F (21.1C) and pressure of 14.7 psia (1.013 bar (a)).
It is available for service in fluid temperatures from -100 to 850F (-73 to 454C) and pressures to 1000 psig [69 bar (g)].
GF92 Inline Flow Meter.
The GF92 is a heavy-duty flow meter that offers excellent low-flow measurement characteristics and is ideal for applications such as compressor fuel monitoring, nitrogen purge monitoring, digester gas monitoring and hydrogen make-up gas.
It can be used in tubing or pipe lines ranging in size from 0.125 to 3 inches (3.2 to 76mm).
Flow sensitivity ranges from 0.006 to 2000 SCFM (0.01 to 3398 NCMH) at a standard temperature of 70F (21.1C) and a pressure of 14.7 psia [1.013 bar (a)].
It operates in fluid temperatures from -50 to +350F (-45 to 177C) and at pressures to 1000 psig [69 bar (g)].
