Automatic Version of Ostwald Viscometer for Conductive Liquids

摘要

In this automatic version of Ostwald electro viscometer some major modifications have been introduced. Namely, we have inserted the Pt wire level sensors within upper glass bulb, modified electrical circuitry with logic XOR gate, added digital stopwatch to find the time of fluidity of some liquids very accurately. In modified version of viscometer there is no requirement of any type of glass window of thermostat to check the liquid levels during fluidity at high temperature. The viscosity measurements were done through electro viscometer with an accuracy of +/- 0.001 mPa s.
