FIELD: measurement equipment.
SUBSTANCE: invention relates to the impeller sensitive element fixed in a driving head of a rheometer which is used for measurement of rheological characteristics of the fluid mediums containing solid particles in the wide range of temperatures and shear rates. Devices for measurement of rheological characteristics of fluid mediums with solid particles in a wide range of temperatures and shear rates allow to obtain more accurate rheological characteristics. Temperatures of measurements can be very high, over 100°C, and the used values of shear rates are typical for production pipeline systems.
EFFECT: creation of impeller sensitive elements allowing to conduct rheological studies the results of which relatively accurately reflect the actual operating conditions, and also allowing to measure accurately the rheological properties of the liquids containing solid particles and to prevent sedimentation of solid particles in samples of liquids when performing rheological measurements.
