Instrument overview
The CANNON® Mini-Rotary Viscometer is designed for precision
control of temperature over time, enabling accurate yield stress and
viscosity measurement of oil samples in conformance with ASTM D
3829, ASTM D 4684, ASTM D 6821 and ASTM D 6896 test methods.
Test procedure
Oil samples placed in the CMRV-4500 viscometric cells are heated and
cooled at a predetermined rate according to a user-specified cooling
profile. The cooling profile parameters are downloaded to the CMRV4500 onboard memory via a serial interface with the host computer. The
CMRV-4500 then uses this profile to control the rate of temperature
change, independent of the host computer.
All three methods specify that the samples be initially heated to ensure
that all components of the sample are released into solution. The samples
are then slowly cooled to the test temperature using the user-selected
temperature profile and maintained at test temperature for a specified
soak period. Following the soak period, apparent viscosity (and yield
stress if applicable) for each sample is determined by applying a constant
torque to, and measuring the rotational speed of, a cylindrical rotor which
has been immersed in the sample.
The time required for completion of the ASTM D 3829 test cycle is
approximately 19 hours. The time required for completion of the ASTM
D 4684 (TP-1, two-day) test is 45½ to 53½ hours. The time required for
completion of the ASTM D 6821 test cycle is approximately 18 hours.
The time required for completion of the ASTM D 6986 test cycle is
approximately 43½ to 53½ hours.

CMRV-4500 APPARATUS
CMRV-4500 unit/accessories
The CMRV-4500 unit contains an aluminum block with
a heater for warming the
block. Nine viscometric cells
are closely fitted into nine
holes in the block (see photo).
There are also two thermometer wells in the block.
Lower rotor bearing
Each viscometric cell
consists of an aluminum
block aperture with a
rotor resting in a stainless
steel cup at the base. The
rotor is attached to a rotor
shaft with a pivot point at
the bottom. The pivot
point fits a mating
conical depression at the
bottom of the stainless
steel cup; this mechanism
serves as the lower
bearing. The standard rotor composition is hardened stainless steel. The
drive line rotor composition is Delrin
(NOTE: The drive line rotors/pins/
weights must be purchased separately
from CANNON®.)
DESCRIPTION

Rotor crossbar
Rotor locking pins
Pulley-wheel assembly
The rotor crossbar is
used to hold the loop
at the end of the
thread. It also serves
as an indicator for
(optional) manual
timing of rotor
rotation.
The rotor locking pins
String on rotor and pulley-wheel assembly
are used to prevent
unwanted rotor rotation. When the locking pin is lowered over the rotor
crossbar (see photo), rotation is prevented. When the pins are in the
raised (detent) position, the rotors are free to rotate.
The pulley-wheel
assembly consists
of a V-channel
timing wheel with
a digital-optical
sensor permitting
precise measurement of the wheel
rotation. The
pulley-wheel base
is designed to be
fitted to the
CMR V-4500 slide
track adjacent to
the viscometric
cells. The probe
Slide track with pulley-wheel assembly
cable is connected to the jack on the front of the CMRV-4500 housing.
Winding thread
Slide track
CANNON
The thread used for CMRV-4500 testing is a single, nonelastic strand of
70 cm (28") winding thread of silk, cotton, or similar material (Coats
North America or comparable brand, 0.1 mm radius) with a loop on one
end. One end is wound around the CMRV-4500 rotor. The other end of
the thread is tied to a small rigid plastic ring from which the test weight
may be suspended.
The pulley-wheel assembly is designed to interlock with the pulleywheel slide track and move laterally so it can be aligned with the scored
marks on the track opposite each of the nine rotor shafts.

Hook-weights
Temperature probe
Thermometers
Hook-weights are hung on the plastic ring at
the free end of the thread to apply the required
force to the rotor during yield stress and
viscosity measurements. Nine disk weights,
one hook-cage, and one larger hook-weight are
provided. Weights vary depending on the
ASTM Method used for testing.
CMRV-4500 block temperature is detected by
a 3k-ohm temperature probe, which must be
seated securely in the thermistor aperture at the
rear of the CMRV housing and plugged into
the electronic chassis.
Hook-weights
The CMRV-4500 unit is shipped from CAN-
®
with two thermometers to be used to check the temperature of the
NON
block.
The long thermometer used for the probe and cell calibrations is a
PRINCO mercury-thallium calibrated thermometer with a range of
-46°C to +30°C in .2°C increments and an accuracy of ± 0.01°C
below 20°C.
NOTE
If a thermometer is removed from the CMRV-4500 when the unit is
cooling, plug the thermometer aperture in the Plexiglas® cover to prevent
ice formation around the rotors.
The shorter, high-temperature uncalibrated thermometer has a range
of 0°C to 105°C in 1°C increments with an accuracy of ± 1°C.
Air/Water Heat Exchanger
CMRV-4500 cooling is
accomplished with internal
thermoelectric cells and an
external Air/W ater Heat
Exchanger circulating a
mixture of water and
antifreeze to remove heat
from the thermoelectric
modules.
The Air/Water Heat Exchanger contains the electronics necessary to monitor
the coolant flow rate and regulate the action of the circulating pump
during the running of ASTM-specified temperature profiles. The Heat
Exchanger also supplies DC power for the operation of the CMRV
thermoelectric modules.

Front panel operations
CMRV front panel
Control features
CMRV front panel control features are simple and functional. The central
switch on the front panel is the power switch for the unit. The lightemitting diodes (LEDs) above the switch indicate function of the heating
and cooling systems. The Sensor connection on the right side of the
panel mates with the cable from the pulleywheel optical sensor. The Start
Test button on the left side of the panel is used to initiate CMRVcontrolled testing and calibration routines. The Yield and Viscosity
LEDs light during yield stress or viscosity testing.
