I. INTRODUCTION
e Brookeld DVE Viscometer measures uid viscosity at given shear rates. Viscosity is a measure
of a uid’s resistance to ow. You will nd a detailed description of the mathematics of
viscosity in the Brookeld publication “More Solutions to Sticky Problems”, a copy of which
was included with your DVE and can be downloaded in pdf form from the Brookeld website,
www.brookeldengineering.com.
e principle of operation of the DVE is to rotate a spindle (which is immersed in the test uid)
through a calibrated spring. e viscous drag of the uid against the spindle is measured by the spring
deection. Spring deection is determined optically by measuring the shi in the spindle position
due to the viscous drag of the uid against the spindle. e measurement range of a DVE (in Poise,
centiPoise, Pascal or milliPascal seconds) is determined by the rotational speed of the spindle, the size
and shape of the spindle, the container in which the spindle is rotating, and the full scale torque of the
calibrated spring.
ere are four basic spring torque series oered by Brookeld:
Spring Torque
Model dyne-cm milli Newton-m
DVELV 673.7 0.0673
DVERV 7,187.0 0.7187
DVEHA 14,374.0 1.4374
DVEHB 57,496.0 5.7496
e higher the spring torque, the higher the measurement range. e viscosity measurement range for
each spring torque may be found in Appendix A.
All units of measurement are displayed according to either the CGS (cP) system or the SI (mPa•s) system.
1. Viscosity appears in units of Poise (shown as “P”), centipoise (shown as “cP”), Pascal Seconds
(shown as “Pa•S”) or milliPascal-seconds (shown as “mPa•s”) on the DVE display.
2. Torque appears in units of dyne-centimeters or Newton-meters (shown as percent “%” in both
cases) on the DVE display.
e equivalent units of measurement in the SI system are calculated using the following conversions:
SI CGS
Viscosity: 1 mPa•s = 1 cP
Torque: 1 Newton-m = 107dyne-cm
1 Pa•S = 10 P
References to viscosity throughout this manual are made in CGS units. e DVE Viscometer provides
equivalent information in SI units (see Section II.5: Viscosity Units).

II.3SpindleSelecon
DVELV Viscometers are provided with a set of four spindles and a narrow guard leg; DVERV
Viscometers are provided with a set of six spindles and a wider guard leg; DVEHA and DVEHB
Viscometers come with a set of six spindles and no guard leg (see Appendix F for more information
on the guard leg).
e spindles are attached to the viscometer by screwing them onto the coupling nut on the lower
sha (see Figure II-6). Note that the spindles have a le-handed thread. e lower sha should
be secured and slightly lied with one hand while screwing the spindle to the le. e face of the
spindle nut and the matching surface on the lower sha should be smooth and clean to prevent
eccentric rotation of the spindle. Spindles can be identied by the number on the side of the spindle
coupling nut.
e DVE requires a spindle entry code number to calculate viscosity values. e two-digit code for
each spindle can be found in Appendix D.

AMETEK Brookeld Page 16 Manual No. M15-356-B0916
Note: The DVE will display the spindle entry code that was in use when the
power was turned off. Not all spindles have an entry code number that is
the same as the spindle number. For example: the spindle code entry for
spindle LV-1 is 61 and the spindle code for the UL Adapter is 00.
e motor should be OFF whenever spindles are being removed or attached.

Note: When the motor is ON, any change to the selected speed will be eective

measured torque value and measured viscosity.
e DVE Viscometer employs an optical signal pick-up inside the instrument to detect the torque
value of the calibrated spring. is optical signal pick-up is recorded four times per revolution of
the spindle. When the spindle begins to rotate at a dened speed, four torque values are recorded
during the rst full revolution of the spindle and averaged together. e display reports the average
value for both torque (%) and viscosity (P, cP, Pa•S or mPa•s). ereaer, the next torque value
recorded by the optical signal pick-up is averaged together with the three preceding torque values
and the newly calculated torque (%) and viscosity (P, cP, Pa•S or mPa•s) values are then displayed.
is 4x revolution pick-up and display continues as long as the motor is on.
is algorithm in the instrument rmware is used for all viscosity and torque readings. Consequently,
the wait time to observe the initial displayed readings for torque and viscosity increase with lower
speeds.
It may also be necessary to allow time for the indicated reading to stabilize.
Note: Atspeedsof1 RPM andlower, additional timemayberequiredtoallowfor complete
deection of the torque sensor. e % (torque) and cP (viscosity) will ash until
2 revolutions are achieved and the % torque value is greater than 10%.
e time required for stabilization will depend on the speed at which the Viscometer is running
and the characteristics of the sample uid. For maximum accuracy, readings below 10% should be
avoided. Additional information on making viscosity measurements is available in Appendix B or
the Brookeld publication “More Solutions to Sticky Problems”.
e DVE Viscometer will remember the selected speed and spindle when power is turned o. On
start-up, the viscometer will be set to the previously selected spindle and speed.
Please see Brookeld publication, “More Solutions to Sticky Problems” (Chapter 3), for information
on how to select a speed.

mPAS (mPa•s) Millipascal Second 1 mPAS = 1 cP = 0.01 P = 0.001 PAS
PPoise 1 P = 100 cP = 100 mPAS = 0.1 PAS
Changes to the currently displayed viscosity units are made from the Visc Units screen in the Options
Menu. To change the currently displayed Visc Units, press and hold both the SPEED UP and SPINDLE
UP arrow keys simultaneously to display the Options screen. Use the SPINDLE UP or DOWN arrow
keys to navigate to the Visc Units screen. Push the RANGE key to accept the Visc Units option. To
change the currently set viscosity units, press the spindle up or down keys to scroll to the required
value. Press the RANGE key to accept the change and return to the Default screen.
II.6Range
In the Default screen, pressing the RANGE key allows you to determine the maximum viscosity (full
scale reading) that can be measured by a spindle and speed combination when used with the specic
spring torque of the DVE Viscometer. is value represents the measured viscosity which will be
displayed when the instrument’s % torque reading is at 100. Pressing the key at any time will cause
the current viscosity display to change and show the maximum viscosity. e screen torque display
will now display 100% to indicate this special condition. e maximum viscosity and 100% value
will be displayed for as long as the RANGE key is depressed. Figure II-9 shows the RANGE function
where the No. 2 RV spindle is rotating at 10 RPM. e Full Scale Range is 4000 cP (or 4000 mPa•s).
4000 cP
10RPM 100% s02
Figure II-9
Brookeld recommends that viscosity measurements be made only when the instrument’s % torque
value is between 10 and 100. e FSR (Full Scale Range) represents the maximum value that can be
measured (100% on the torque scale). e minimum viscosity that can be measured is 10% of the
FSR (equivalent to 10 on the torque scale).
Full Scale Range is the same as Range or Autorange on previous versions of Brookeld Viscometers.
e accuracy of the Brookeld Viscometer is expressed as a percentage of the instrument’s FSR.
When using the standard LV (61-64) and RV (2-7) spindles, the instrument’s accuracy is ±1% of
the FSR (see Appendix E).

II.7OutofRange
e DVE gives indications for out of specication or out of range operation. When torque %
readings exceed 100.0% (over range), the display changes to that shown in Figure II-10. You must
either reduce the speed or use a smaller size spindle to correct this condition. Audible noise may
be heard in this case.

If you operate at spindle speeds that produce torque below 10.0% (under-range), the DVE displays
both torque % and viscosity (cP) with ashing unit designations, as shown is Figure II-11. You must
either increase speed or use a larger size spindle to correct this condition.
e parameters of torque % and viscosity (cP) will also ash prior to two complete spindle revolutions.
It is not recommended that readings are taken while parameters are ashing.

Negative torque % will be displayed as shown in Figure II-12. Viscosity values will be displayed as
“- - - -” when the torque % is below zero.
