Abstract

It has been shown theoretically that the use of a capillary with an annular cross section instead of a cylindrical one reduces the kinetic correction in viscosity measurements using capillary viscometers. A description is given of a viscometer designed for the electric-contact measurement of the viscosity of electroconductive liquids in fractions of a second with an accuracy of 0.1%. In order to increase the reproducibility of the time readings, the electrodes are sealed into the upper part of the reservoir bulb, which is not wetted in the course of measurement. Time is measured by counting electronic pulses at 10-kc frequency using a millisecond counter.
