A process and a device for determining the viscosities of liquids are described, which work quickly, reliably and accurately. The process according to the invention makes use of the fact that disturbing effects are eliminated when measuring the change in the rate of flow of the liquid from the viscometer, while utilizing the change in the hydrostatic pressure during viscosity measurement and that the viscosities can be reliably determined from the measured data by the Hagen-Poiseuille law. The viscometer according to the invention is designed so that the hydrostatic pressure change during measurement is maximal.

Process and device for determining the viscosity of liquids

A capillary viscometer in which the liquid meniscus is detected by sensing electrical resistance changes in hermetically sealed electrical resistors which are spaced apart at the two levels in the measuring tube in which the meniscus is to be detected. The resistors are encased in glass and the electrical leads to these resistors are passed through glass tubes to a cable connector.
