ABSTRACT:
A vibration viscosimeter having a resilient wire loop to be vibrated and an electrical drive therefor. The energizing signal for the drive is alternately kept 30 degrees lagging and 30 degrees leading the vibration or vice versa. Viscosity may then be computed as a function of the signal periods and six constants.
