Abstract: Method and apparatus for measuring the viscosity of a liquid is set forth wherein an oscillating element is used to cause excitation of a comparative medium and the damping behavior of the comparative medium is determined as a function of time. The same oscillating element is used to determine the damping behavior of the test liquid as a function of time. The thus measured damping behaviors are compared to determine the viscosity of the liquid.

Abstract: An arrangment for measuring the viscosity of a fluid includes a heated, vertical container which receives a vessel filled with the fluid to undergo a viscosity determination. A pair of vertically spaced sensors are mounted in the peripheral wall of the container and are connected with an evaluating mechanism which includes a timer and a computer. The sensors are also connected with a temperature regulating mechanism which regulates the temperature of the fluid by controlling heating of the container. In operation, the fluid is heated on a predetermined temperature. A standard sphere is then permitted to fall through the fluid. When the sphere passes the uppermost sensor, the latter generates an impulse which activates the timer. Similarly, an impulse deactivating the timer is generated when the sphere passes the lowermost sensor.
