- description: Capillary viscometers VPZh are used to determine the kinematic viscosity of transparent liquids at positive and negative temperatures in all industries where fuel and lubricating oils are used, in oil refinery laboratories, in mechanical engineering, construction, etc.ks-company.prom.uaCapillary viscometersPrinciple action is based on the calculation of the time of flow of a given volume of liquid through a narrow hole or tube, at a given pressure difference. Most often, the liquid from the tank flows out by its own weight, in which case the viscosity is proportional to the pressure difference between the liquid flowing out of the capillary and the liquid at the same level flowing out of a very thick tube. If the flow of liquid in the device is carried out only under the influence of gravity (for example, in the Ubbelohde viscometer), then during the operation of the capillary viscometer, the kinematic (not dynamic) viscosity is determined. The capillary viscometer measures viscosities from 10 µPa s (gases) to 10 kPa s. Use viscometers according to ASTM D 445 (GOST 33).ks-company.prom.ua
