Viscosity (cP)
In taking viscosity measurements with the DV-I+ Viscometer there are two considerations which
pertain to the low viscosity limit of effective measurement.
1) Viscosity measurements should be taken within the equivalent % Torque Range from
10% to 100% for any combination of spindle/speed rotation.
2) Viscosity measurements should be taken under laminar flow conditions, not under turbu-
lent flow conditions.
The first consideration has to do with the accuracy of the instrument. All DV-I+ Viscometers
have a full scale range allowable error of (+/-) 1% of any spindle/speed in use. We discourage
taking readings below 10% of range because the potential viscosity error of (+/-) 1% is a rela-
tively high number compared to the instrument reading.
The second consideration involves the mechanics of fluid flow. All rheological measurements of
fluid flow properties should be made under laminar flow conditions. Laminar flow is flow wherein
