Designed for precision flow switching and flow measurement in rugged industrial applications, FCI’s FLT93 switch, ST98 Flow meter, and GF90 and GF92 Flow meters have received IEC/IECx approvals for their safe use from the International Electrotechnical Commission (IEC).
The IEC prepares and publishes international standards for electrical, electronic and related technologies. These serve as a basis for national standardisation and as references when drafting international tenders and contracts.
Through its members, the IEC promotes international cooperation on all questions of electrotechnical standardisation, such as the assessment of conformity to standards, in the fields of electricity, electronics and related technologies.
FCI’s advanced thermal mass flow switches and flow meters are recognised worldwide for their precision flow measurement, high reliability in rugged operating conditions, low maintenance, long-life and low cost-of-ownership.
Their highly intelligent microprocessor-based designs feature a no-moving parts thermal mass flow sensor, which makes them ideal for a broad range of industries, including: chemical, energy and power, food/beverage, oil/gas, pharmaceutical, water/wastewater treatment and more.
The Flow/Level/Temperature (FLT) Flow switch reliably monitors the flow, level and temperature of liquids, gases, slurries, syrups, lubricants, coolants and more.
The flow switch is ideal for tank level monitoring and pump low-flow protection applications. The FLT features a wide set-point range, which varies according to service media (liquid, gas or foam), beginning from 0.003 to 0.9 SMPS in water-based liquids.
IEC approved models include: FLT93B basic, FLT93C sanitary insertion, FLT93F insertion ultra fast response, FLT93L inline low flow and FLT93S insertion fast response.
ST98 Flow meter:
The rugged ST98 Flow meter sets the industry standard for performance and value with a reliable thermal mass flow sensor in a smart electronics package.
The ST98 operates over a wide flow range from 0.21 to 172 NMPS in air with a standard flow accuracy of +1 % of reading, +0.5 % of full scale.
ST98 Flow meter is ideal for a wide range air/gas flow measurement applications, including natural gas or methane monitoring, compressed air metering, industrial HVAC systems, nitrogen blanketing and combustion air.
IEC approved models include the ST98, ST98B basic and ST98L inline.
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.
GF90 is suitable for use in ducts or pipes with a minimum 50 mm nominal inside diameter.
Flow sensitivity ranges from 0.08 to 488 NMPS at a standard temperature of 21.1°C and pressure of 1.013 bar (a). It is available for service in fluid temperatures from -73 to 454ºC and pressures to 69 bar (g).
GF92 inline Flow meter:
The GF92 is a heavy-duty flow meter that offers ideal low-flow measurement characteristics and is ideal for compressor fuel monitoring, nitrogen purge monitoring, digester gas monitoring and hydrogen make-up gas.
GF92 can be used in tubing or pipe lines ranging in size from 3.2 to 76mm. Flow sensitivity ranges from 0.01 to 3398 NCMH at a standard temperature of 21.1C and a pressure of 1.013 bar (a). It operates in fluid temperatures from -45 to 177°C and at pressures to 69 bar (g).
The FCI thermal mass Flow switches and Flow meters are available from AMS Instrumentation and Calibration.
