  • Abstract:
  • A viscometer is an instrument used to measure the viscosity and flow parameters of a liquid. Viscosity of a liquid is directly proportional to the flow time through a capillary tube. In glass capillary viscometer the time required for the liquid level to drop from one mark to another is generally measured by a stop watch. As the liquid flows quickly through the glass tube, accurate measurement of time by a stop watch is very difficult. To solve this problem a digital watch is constructed which automatically start at upper mark and stop at lower mark of the viscometer. This apparatus works for electro conductive liquid and gives good results. 2-input EX-OR gate is used for automatic start and stop operations of this digital watch. A new electronic method is used here to measure time of rise or time of fall of liquid level automatically.
