Measuring hydrocarbon waste gases flared
offshore
The GF90 Flare Gas Flow Meter from FCI precisely measures the flow of combustible hydrocarbon waste gases for flare gas system disposal from offshore production platforms, despite varying composition
These dangerous toxic gases often flow at such varying and/or low levels that they become a serious challenge to sense, measure and eliminate With its highly sensitive thermal mass flow sensing element and microprocessor-based intelligence featuring multiple calibration groups, the advanced GF90 Flare Gas Flow Meter delivers precision flow measurement down to 0.25 SFPS

Space-saving Hydrogen flowmeter is approved
The new space-saving ST75V Hydrogen flowmeter with agency approvals for hazardous areas is ideal for oil/gas refineries, ammonia production, food plants, mining, and fuel cell skids
It also can be specified with corrosion and abrasion-resistant alloys, including Hastelloy, Monel and tantalum, and with all-welded construction for service in the harshest environments.
It is available for service in broad range of fluid temperature applications, from -100 to 850F (-73 to 454C) and pressure applications to 1000psig [69 bar].
Designed for complex multi-gas or variable flow processes, the GF90 Flow Meter includes an advanced microprocessor-based programmable transmitter.
The transmitter can store up to three calibration groups.
Each group can be independently configured for a specific calibration range, fluid, switch point settings, etc, to provide accuracy in complicated gas processes.
The instrument is also inherently multi-variable, providing both flow and temperature measurements without any additional tap points.
Developed with constant power technology, the GF90 features turn-down from 1000:1, accuracy of 1 percent of reading plus 0.5 percent of scale, with repeatability of 0.5 percent of reading or better.
Flow sensitivity is from 0.25 to 1600 SFPS [ft/sec at a standard temperature of 70F and pressure of 14.7 psia] or 0.08 to 487.7 NMPS [m/sec at a normal temperature of 21.1C and pressure of 1.013 bar absolute].
The GF90 transmitter electronics are addressable via a built-in LCD display and keypad or through its RS-232C and RS-485 serial ports.
This allows the user to perform in-field programming to change zero, span, switch points and engineering units, or to perform instrumentation verification, troubleshooting and other critical functions.
The serial I/O ports support access to computers or ASCII terminals.
The GF90 transmitter features two independent, field programmable analogue signal outputs of 4-20mA, 0-10Vdc, 0-5Vdc, and/or 1-5Vdc., which can be assigned to any combination of flow and/or temperature.
It also offers dual alarm switch points with relay outputs.
The switch points are user, field programmable to alarm at high, low or windowed and can also be assigned to flow and/or temperature readings.
Dual 10A relay outputs are provided for contact closures to lamps, alarm and control systems.
A NEMA Type 4X (IP66) rated transmitter enclosure is standard.
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 Factory Mutual Research, ATEX, CSA, GOST/RTN, IEC, CPA and NEPSI.
