ML-SP-0705TOV Viscometer System...What is it?:

The TOV Viscometer System . . . what is it?The Mansco Products TOV Viscometer System is a process viscometer designed and built for in-lineuse. It is the most sensitive, stand-alone control device for measuring viscosity and temperature inan in-line environment. It is unlike capillaries or laboratory viscometers in that the TOV

is installed directly into the main process pipeline . . .no sidestream is needed. It is unlike any other vis-cometer because of its sensitivity, repeatability,robustness, and low maintenance requirements. And,Mansco Products provides installation, training, andcomprehensive support services. In other words, theTOV System is the most effective process viscometeravailable and the TOV System has no peer.

Why the TOV? . . . why is the TOVViscometer System so much better?

Quite simply, the engineeringand “know-how” incorporated intoeach TOV System is what makesthe TOV better. For example, theTOV operates at a low shear rate.By definition, viscosity is the ratioof shear stress to shear rate. Inturn, the TOV measures shearstress of the process fluid todetermine the process viscosity.Sounds easy, right? . . . Well, it’snot that simple. The instrumentmust be engineeredand designed towithstand the harshoperating environ-ments of process lineswhile providing highsensitivity andrepeatibility levels forvery reliable processcontrol . . . all whileeliminating the effectsof the plant environ-ment. The TOV doesjust that.

- Reliability & Repeatability:With a repeatability factor ofover 99.5%, the TOV producesthe same results over and overagain, day after day, week afterweek, year after year.

- Very User-Friendly: Afterinitial set up, the TOV requireslittle or no maintenance . . .including calibration.

- Durability: The TOV System isvery durable. Many TOV’s havebeen installed in pipelines for adecade or more without interrup-tion.

- Lab-Like Results in Real-Time:The TOV is designed so thecustomer can measure viscosityand temperature within range andwithin the target viscosity level.

Why “in-line”?Viscosity is a rheologicalproperty . . . meaning aproperty involved with thedeformation of flow. The keyword is flow. The best locationto measure and control aproperty of the flow is withinthe flow itself . . . not alongside the flow (a sidestream)and not in a laboratory. Themeasurement and control ofviscosity (and temperature)directly in the flow providesreal time rheological data . . .no lag time and no processdelays. In the end, plants willachieve the highest processefficiency while improvingproduct quality.

ML-SP-0705TOV Viscometer System...What is it?:

What is viscosity and why is it so important?“All fluids possess a

definite resistance to changeof form and many solids showa gradual yielding to forcestending to change their form.This property, a sort of internalfriction, is called viscosity; it isexpressed in dyne-secondsper cm2 or poises.”* In termsof physics, viscosity is theratio of shear stress to theshear rate. The viscosity of apolymer decreases as shearrate increases. This propertyis referred to as pseudoplasticbehavior or shear thinning.

More About Shear Rate:Intrinsic Viscosity, Shear Rate, & the TOV Viscometer System

In a condensationpolymerization process thematerial exits the “finisher”and moves slowly towardspinning with a shear rate ofless than 10 sec-1. To obtainthe most reliable viscositymeasurement apparentviscosity at different shearrates should be analyzed.

At low shear rates theviscosity remains near η0,sometimes referred to as theintrinsic viscosity. But as theshear rate of measurementincreases, the apparentviscosity drops until reachinganother asymptotic plateau ,called the Philappoffianregion. The reason for thedecrease of apparentviscosity with increased shearrate is not all segments of a

TOV ApplicationsThe general rule is that: “If the fluid can be pumped,

then it can be measured using the TOV System.Applications include, but are not limited to:

The TOV ViscometerSystem (TOV) measuresviscosity well before thePhilappoffian region, atmuch lower shear rateswhere the measurement ofviscosity is much moresignificant. With itsunsurpassed sensitivity atits operating shear rate,the TOV provides muchmore effective results on amore repeatable basis.

Please note: Each TOV System iscustom designed to meet each applicationsneeds and specifications. The TOV sensoris selected and designed for optimalviscosity measurement while the Trans-ducer is calibrated for optimal narrowranges within the product specifications.

Viscosity is a rheologicproperty. Rheology is thescience of deformation andflow of materials. Viscosity isjust one of the many importantrheological properties. Be-cause of this inter-relation,viscosity can be used as anindirect measurement ofproperties such as crystalconcentration, and otherimportant properties. In otherwords, with the accuratemeasurement of viscosity,plants can tightly control thierentire process flow.

TOV Viscometer System...What is it?:

What we need toknow about yourproduct and process

Because each TOVSystem is customized foreach process and installa-tion, we need to understandyour product(s) and process.

For product information,product family (polyester,nylon, etc.) and targetviscosity & temperaturerange are importantconsiderations whendesigning and manufacturinga customized TOV .

For process information,data for the polymerizationprocess method (CP,autoclave, etc.) andoperating pressure rangeare important TOV consider-ations.

For TOV Adaptor design,whether we make theAdaptor or the customermanufactures locally, thepipeline specifications areneeded. The core pipe size,schedule and materials ofconstruction are importantconsiderations. And, if the ajacket is present, the jacketspecifications are needed.

Finally, to ensure properlocation of the TOV Probeinstallation, we need yourhellp by providing a sketchor even pictyures of theprocess with availablelocations for Probe installa-tion. This is even moreimportant in vessels whereagitators are present. Withyour help, we can worktogether to select a locationwhere the Probe can besuccessfully installed toproduce the results youexpect.

TOV Installation:Where Should the “TOV” Be Installed?

TOV Systems are custom de-signed. Characteristics of theprocess fluid, the Probe’s instal-lation location, and other specif-ics are important considerations:Probe Location:The most common pipeline in-stallation of a TOV Probe is in apipe elbow. Straightline loca-tions are also acceptable. In ei-ther, the Probe is installed intothe main process pipeline and ina location where viscosity con-trol can take place as possible.

In vessel installations, the Probeis often located in a recycle line(pipeline installation) or into thevessel itself near the exit.

Features of note:Adaptors are designed for mini-mal disruption to the processflow. The contours of the Adap-tor are engineered and ma-chined to match the pipeline.The Adaptor incorporates safetyfeatures such as the Flow Split-ters to protect the TOV Probe.

Homogenous Flow:Fully developed, well mixed flowis an important consideration forany in-line measurement suchas viscosity, temperature orpressure. In installations wherethe Probe will be considerablyaway from a mixing action(pump, static mixer, etc..), a newlocation or the addition of amixer should be considered.

How it works . . . The TOV Probe’s sensing device is immersed in process fluid.

The TOV Probe is allowed to oscillate at its own resonancefrequency…no motors or gears.

Power to start and maintain the TOV Probe’s oscillation issupplied by the TOV Transducer.

As the viscosity increases, more power is needed to maintainthe oscillation. For a lower viscosity, less power is needed.

The Transducer continually monitors how much power isneeded meaning the viscosity is also constantly monitored.

No sampling time….only REAL TIME measurement.

. . . Why the “TOV”√√√√√

The Most Sensitive and Reliable Device Available:Superior engineering and know-how used in eachTOV System provides the most sensitivite, accurate,and reliable measurement available.

Provides Real-Time Results: Unlike lab samplingand other methods, the TOV system is a true in-linedevice providing real time results.

Improves Quality Control: The TOV System isa quality control instrument. Better and tightercontrol means better quality, better price per produc-tion, and, ultimately, better business.

Stand-Alone Device: The TOV can operate with aDCS system or separately from other control devices.In the event of a control system failure the processcan continue to operate with confidence of reliableviscosity and temperature measurement.

Increased Operating Efficiency: There are no time delays waiting for labresults resulting in operating inefficiencies and process delays. real-time controlmeans more higher grade product with less scrap or low grade product. In time,the TOV pays for itself simply through improved quality control.

Developed and manufactured by a proven company with asubstantial track record.
