When Existing Flow Technologies Aren’tPrecise Or Reliable Enough, QUANTIM® CanReplace Or Enhance Them.

Pumps, weigh scales, and thermal mass instruments all have limitations.Until recently, the best technologies to measure and control small flowshave had serious limitations, leaving researchers and process users littlechoice but to cobble together makeshift solutions to try to meet theirneeds.

Until QUANTIM, that is. QUANTIM is the first miniaturized Coriolis flowdevice that measures and controls mass addition directly, without regardto fluid properties or conditions. QUANTIM’s Coriolis technology plusintegrated valve and PID control bring a new level of measurement accuracy and control to critical applications that require more precisionand reliability than older technologies can provide.

Pumps meter volume, not mass.All pump users know that pumps operate by displacing a volume. Inmany cases, the mass of fluid added to a process or experiment is muchmore important than its volume. Equally, pump surfaces can degradeover time, further undermining assumptions that one might have madeconcerning the relationship between volume flow and mass flow. Finally,pumps need routine maintenance and calibration that require their periodic removal from service.

Weigh scales are expensive and cumbersome.Customers who desire the measurement of precision mass additionsometimes use a scale or balance to monitor loss of mass from the supply vessel. As with all precision gravimetric techniques, the scalemust be isolated from environmental influences on the measurement,such as air drafts, temperature changes, and vibration, leading to anexpensive and cumbersome system. Importantly, the instantaneousmass flow rate cannot be determined or controlled with a weigh scalesystem, merely the average mass flow rate over time.

Thermal mass can’t handle process variability.Thermal mass flow devices have been used for decades in precision flowapplications. For many users — particularly in gas applications — theywork very well, provided that flow conditions are known and remain stable. But thermal devices operate on an inferred measurement whichmakes them susceptible to process variability. As fluid type, temperature, density, pressure or recipe changes, accuracy is reduced. Non-idealgases, such as CO2 and hydrocarbon gases, are very difficult to measurewith any reasonable accuracy using thermal devices.

Ruggedly constructed for the lab or the plant.QUANTIM is the perfect replacement for a laboratory device like a

precision syringe pump. But it’s equally at home in a process plant

environment. The QUANTIM’s 65ºC maximum operating temperature

permits it to be used in almost any ambient environment. QUANTIM is

also available in an explosion-proof enclosure for Zone 1/Division 1

hazardous areas and in an IP-65/NEMA-4X Division 2 package suitable

for wash-down. Only QUANTIM permits laboratory-grade flow

measurement and control in real plant/process applications.

Sophisticated integral solenoid valve providesclosed-loop measurement and control.Unlike other flow devices, the QUANTIM controller incorporates its

own solenoid control valve and PID control for seamless continuous

measurement and control. With QUANTIM, there’s no need to select

an external proportional control valve and design your own PID loop.

Compact size fits anywhere in your lab or process.QUANTIM is so small that it fits in the palm of your hand, which means

it can fit neatly into your lab, process, or OEM application. Just drop it

in and it’s ready to go. No calibration is required.

Totally immune to fluid process changes.QUANTIM’s Coriolis sensing technology is not fluid or process

dependent so it provides accurate mass flow measurements across

a wide range of flow conditions. The standard factory calibration

assures accurate measurements regardless of fluid viscosity, density,

temperature, or pressure.

Simultaneous density measurement.QUANTIM automatically measures fluid density and can output the

density value. Many users rely on the density information for its intrinsic

diagnostic value: confirmation that the correct fluid is flowing,

detecting the presence of entrained gas, or detecting the interface

between two fluids.

Chemical Catalyst Research

QUANTIM Application Versatility

Precision Coatings

Chemical Injection/Dosing Systems

Catalysts are the driving force behind advancements in the chemicalindustry. The challenge is scaling up the catalyst process from the laboratory to the pilot plant and, ultimately, to production levels. Reactive catalysts are typically large surface-area particles bonded to a

larger structure. It’s imperative that the amount of feed flowing through the research catalyst bed be precisely andaccurately measured so that the conversion rate and selectivity can be accurately calculated. Normal catalyst development results in incremental improvements in conversion rates and selectivity. Errors in measurement atthese very low flows will be amplified upon scale-up. Thus, flow measurement accuracy is critically important.QUANTIM offers high accuracy mass measurement and control.

Examples: Petrochemical catalyst research, refining desulphurization catalyst research

Many critical coating processes use liquids that are sprayed onto surfaces. The delivery rate to the spray nozzle controls the film thickness on the object while gas flow determines droplet size andspray pattern. Precision coating processes require tight control ofcoating thickness, must be reproducible and minimize liquid waste.Medical device coating is an example of a process requiring extremeliquid flow precision. These coatings may contain an active drugwhich has to be evenly distributed and must also contain the correct

dosage for the device. QUANTIM is perfect for controlling the flow rate to the spray nozzle. Gas flow is controlledusing a thermal mass flow device.

Examples: Cardiac device coating, catheter coating, pill coating, fragrance dispensing

Injecting a very small flow of chemical liquid into a larger stream isa common control challenge. Traditionally, a flowmeter measuringthe larger stream creates pulses for a displacement pump to squirta fixed volume of chemical into it. Because the pump volume isfixed, the frequency of pulses can be low enough during low-flowconditions to result in uneven addition of the chemical.

QUANTIM is an ideal solution for metering and controlling thelow flow of the chemical into the larger stream. A flow meter onthe large volume line generates a continuous flow signal. This signal becomes the setpoint for the QUANTIM, which will control

the flow based on a fixed ratio of injectant to large flow. The result is a steady concentration of chemical in thelarger stream. QUANTIM also provides a positive feedback of actual delivery amount, which can be useful fordocumenting injection volumes.

Examples: Natural gas and propane odorization, gas humidification, fuel additives, fuel cells

Metering Pump ControlMetering pumps are open-loop devices that normally cannotprovide any positive feedback of actual delivery rate to theprocess. The solution to this is a QUANTIM flow meter whichcan be used in-line with a metering pump to document actualflow or can be used to provide a fluid demand signal to thepump. The responsive Coriolis sensor provides feedback forsuch cyclical flows produced from a positive displacement pump.

Examples: Chemical research, pilot plants process plants

High Pressure GasesAccurate measurement and control of a gas is not always easyunder high pressure conditions. Certain gases become supercritical under even moderate fluctuations in pressureand temperature. Supercritical gases are difficult to measureusing traditional thermal flow sensors since the heat capacitycan vary greatly over a small shift in temperature. QUANTIM isideal for measuring and controlling supercritical gases.

Examples: Supercritical carbon dioxide, supercritical hydrocarbons such as ethylene

MetrologyThe performance of many low flow metering instruments suchas pumps, injectors, and dispense heads must be periodicallyverified and calibrated. As a true mass measurement transferstandard, QUANTIM is ideal for this application. QUANTIM’sCoriolis sensor is fluid independent, resulting in a very flexible

flow standard for metrology applications. Importantly, because QUANTIM can function as a flow meter or flowcontroller, it can verify passive flow sensors or actively control flow to a device.

Examples: Flow laboratories, fuel cells, analytical devices and hydraulic devices

Vacuum Thin Film CoatingIn certain types of industrial and high tech manufacturing processes, the ability to create a thin chemical coating or film is critical. Many of the chemical precursors used to create these films are liquid at room temperature and must be vaporized prior to entering the process chamber. The problem is that typical vaporizers use very high heat to create vapor, which causes the

delicate precursors to decompose, clogging the vaporizer and contaminating the process. The Brooks®/MSP Turbo-VaporizerTM, with its fine droplet atomizer and recirculating gas heat

exchanger, provides an ideal solution. Carrier gas, heated to the temperature of the liquid, quickly, yet gently, vaporizes the atomized liquid, resulting in a pure, clean vapor. And the Brooks/MSP Vaporizer accommodates up to 3 liquids at once for processes such as doped silicon oxide. The precise flow control of QUANTIM, coupled with thorough mixing of the vapor components, results in outstanding stoichiometry.

Examples: Semiconductor CVD/ALD coatings, metal hard coating, diamond-like coatings
