New FCI Mass Flow Meter Optimized For Biofuel and Biomethane Applications

Biogas, Biogas Fueled Co-Gen Engines, On-Farm and Fermentation Biogas Systems,

Landfill Methane Recovery, Coal Mine Methane Recovery, Municipal and Industrial Wastewater Treatment Digesters

Fluid Components International (FCI) has released its new Model ST51 Mass Flow Meter for owners, operators and manufacturers of biogas production and methane capture and recovery systems. These users will find the new Model ST51 provides the high performance and features required of these applications in an explosion-proof instrument that is easy-to-install, safe and requires virtually no-maintenance to deliver a truly best cost solution.

"This flow meter is designed specifically to solve the unique challenges to flow metering in bioprocess generated methane," said Randy Brown, FCI's Marketing Manager. "The ST51 is the optimum biogas flow meter solution at an affordable price. It features a no-moving parts design that's non-clogging and operates over a wide flow range with low-flow sensitivity. It's packaged in an explosion-proof transmitter, and the calibration is matched to the user's actual gas composition and installation conditions."

In anaerobic digester produced biogas, gas flow measurement is challenged by the wet, dirty nature of biogas. The biogas produced is a potentially dangerous mixed composition of primarily methane (CH₄) and carbon dioxide (CO₂), with smaller percentages of hydrogen sulfide (H₂S) and other gases. The wetness, H₂S and other particulates in the gas create a corrosive condensate that deposits itself on the pipe wall and instruments in the pipe. The gas flow varies widely too—based on fluctuating plant process demands and seasonal variations in temperature and humidity.

FCI's innovative new ST51 Flow Meter is designed specifically to measure biogas and all methane composition gases including natural gas. The ST51 features a thermal mass, insertion-style flow element with flow accuracy to ±1% of reading over a broad flow range from 0.3 to 400 SFPS (0.08 to 122 MPS), and repeatability of ±0.5 percent of reading. The flow

element is available for use in line sizes from 2 to 24 inches (51 to 610 mm) diameters. It operates over a wide turndown range of 100:1, which is essential due to the variable gas flows in wastewater treatment. It operates at temperatures from 0 to 250°F (-18 to 121°C) and withstands pressures up to 500 psig [34 bar (g)].

The new ST51's robust thermal mass flow sensing element has no moving parts and no orifices to clog or foul to attain virtually maintenance-free service in wet, dirty biogas applications. It also includes built-in temperature compensation circuitry for accurate, repeatable measurement year-round as temperatures rise and fall seasonally.

The flow element is constructed with a 316L stainless steel body and Hastelloy C-22 thermowell sensors to resist corrosion. It is approved for use in hazardous environments with approvals that include: FM, CSA/CRN, Class 1, Div 1, Groups B, C, D; Class 1, Div II, Groups A-D, ATEX Zone 1, II 2 G Ex d IIC T6 …T3, II 2 D Ex tD A21 IP67 T90°C…T300°C.

For ease of use and applications flexibility, the ST51 flow meter is rich with outputs for user interfaces and information. Dual 4-20mA analog outputs are user assignable to flow rate and/or temperature, and there is a 0-1kHz pulse output for totalized flow. The transmitter's digital communications include an RS-232C port, and

With units that have the digital display option there is a wireless IR link for PDA use.

The ST51's optional integral digital display features a two-line, 16-character LCD screen that is easy to read and can be rotated in 90-degree increments for optimum viewing and installation flexibility. The LCD screen's top line is assigned to flow rate, and the bottom line is user assignable for temperature readings or totalized flow.

For applications with difficult access or display readability, the ST51's flow transmitter is also available in a remote mount configuration that can be mounted up to 50 feet (15m) away from the flow element inserted the pipe. Both the remote mount and integral transmitters are housed in an aluminum enclosure that is NEMA 4X approved and meets IP67 requirements for water and dust ingress protection. Input power for the ST51 can be selected as either 18 to 36 Vdc or 85 to 265 Vac.

Multicor® Mass Flow Meter

CORIOLIS PRINCIPLE

The Multicor® mass flow meter line uses the science of particle acceleration and its resultant forces to measure flow rate and total weight at accuracies of +/- 0.5%. Space efficiency and overall reliability make Multicor® an ideal choice for feeding, measuring and batching applications involving reasonably free-flowing dry materials.

Multicor® consists of a partitioned measuring wheel, mounted on a drive shaft inside a central dust tight housing. The drive shaft is driven by an electric motor mounted outside Multicor®'s housing. Material enters the unit through an off-center inlet and discharges through a center outlet below the measuring wheel.

In operation, the measuring wheel rotates at a constant speed. Material entering the unit flows into the top of the measuring wheel and is deflected outward in a radial direction creating a "Coriolis force". Multicor® sees this force as a change in torque which is detected by a strain gauge load cell. The output of the load cell is electronically processed to produce flow rate and total weight values at accuracies of +/- 0.5%. Best of all, unlike other flow meters on the market, Multicor®'s performance is not affected by material density, friction or in-feed drop height.

• Flow rates up to 10,500 cubic ft/hr.

• Continuous weighing, batching and gravimetric feeding applications.

• Low installed height

One mass flow meter now does the work of up to three in dirty, explosive or high temperature air/gas environments up to 850 degrees F--thanks to the Multiple Calibration Groups designed into the advanced transmitter developed for the GF90 Mass Flow Meter from Fluid Components International. The GF90 is an insertion type thermal mass flow meter with a highly intelligent microprocessor-based transmitter that stores up to three calibration groups, which can be independently configured for a specific range, media, switch point settings and more. For example, a hydrogen line requiring periodic purging with nitrogen gas can be measured with a single GF90 flow meter by storing the unique calibrations for both of the gases in two of the three available calibration groups in the transmitter. Process engineers who require accurate gas flow measurement, and who also need to simplify complex processes while reducing instrumentation cost, will find the GF90 to be an ideal solution. It is designed for gas flow measurement tasks in the chemical, petroleum, pollution monitoring, steel, wastewater and other heavy industries. Precise measurement of exhaust stack gases, digester gases, hydrogen make-up gases, process gases, and fuel gases are typical applications for the GF Series. The GF90 transmitter's smart 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's transmitter features two independent, field programmable analog signal outputs of 4-20 mA, 0-10 Vdc, 0-5 Vdc, and/or 1-5 Vdc. Dual alarm switch points are designed into the GF90. The switch points are field programmable to alarm at high, low or windowed flow. They are also programmable at high, low or windowed process temperature. Dual 10A relay outputs are provided for contact closures to lamps, alarm and control systems. An auxiliary input terminal is available for connecting the GF Series to external signal sources that provide real-time compensation for complex applications. Through this terminal, composition analyzers, pressure and temperature transducers, densitometers and other devices can perform signal correction for even higher accuracy within close tolerances. The terminal also permits remote switching between the calibration groups. With its thermal dispersion technology flow sensing element and no moving parts design, the GF90 is unmatched in heavy industrial applications. Standard turndown ratio is 100:1, with higher turndown ratios up to 1000:1 possible in some applications. Flow accuracy is ±1% of reading +0.5% full scale. The GF90 supports ducts or pipe sizes from 2 inches [51 mm] diameter and up. The standard flow element has a 1 inch male NPT process connection and an application specific insertion length. Flange connections and field retractable packing gland assemblies are available. Flow sensitivity is from 0.25 to 1600 SFPS [ft/sec at a standard temperature of 70ºF and pressure of 14.7 psia] or 0.08 to 487.7 NMPS [m/sec at a normal temperature of 21.1ºC and pressure of 1.013 bar absolute]. A NEMA Type 4X (IP66) transmitter enclosure is standard, and it comes with configurations for local or remote mount applications. 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. Approvals: Factory Mutual Research, CSA, ATEX and CE Mark. The new VeriCal™ In-Situ Calibration Verification System for the GF90 Air/Gas Flow Meter enables plant technicians to confirm flow measurement accuracy in only minutes without removing the meter from the pipe or process, saving time and money. The VeriCal System is a specially manufactured and plumbed GF90 flow element with additional electronics to feed and measure a precise flow of gas from a nitrogen source. To test a GF90 flow meter, the nitrogen gas is flowed through the meter's flow element and measured at five pre-set measurement points across the meter's range. The in-situ flow meter test data is then compared to original FCI laboratory calibration and installation benchmark test data for the meter.
