Abstract

A viscometer 10 is shown which is modified by the addition of wire probe pairs 11 and 12. The wire probe pairs are provided at spaced joints in the viscometer tube, to detect the presence or absence of a conductive fluid thereat.

Viscosity Measurement for Conductive Fluids

A viscometer 10 is shown which is modified by the addition of wire probe pairs 11 and 12. The wire probe pairs are provided at spaced joints in the viscometer tube, to detect the presence or absence of a conductive fluid thereat.

Each wire probe pair 11 and 12 comprises wires 13 and 14, sealed, by fusing, in the capillary walls of the viscometer 10. Each pair is connected to a timer 15 which continually measures the conductivity of each pair separately. The timer 15 initiates operation when the conductivity between the upper pair of electrodes 11 falls, and continues to run until the conductivity between the lower pair of electrodes 12 falls. The elapsed time is a measure of fluid viscosity.

Alternatively, a single wire may be placed at each of the indicated points 11 and 12 and a ground wire sealed in the wall of the storage bulb 16 of the viscometer 10.
