Construction and Design of Microcontroller Embedded Based Viscometer

Ostwald Viscometer with Photo – Detector system is developed by using Light Emitting Diode and Light Dependent Resistor. The flow time is measured with Microcontroller and output displayed on Liquid Crystal Display. Software is written in computer for the measurement of flow time in embedded `c` and hardware designing is described. The accuracy of the newly designed instrument is in milliseconds.
