ABSTRACT:
A viscosity of liquids is measured by inserting one end of a fine tube into one end of a tubular vessel sealed and maintained at a reduced pressure, while dipping the other end of the fine tube in a liquid to be measured, to cause the liquid to flow into the the vessel through the fine tube under the influence of a difference in pressure between both ends of the fine tube, detecting an internal pressure of the tubular vessel with a pressure sensor connected to the vessel to measure a change of an internal pressure of the vessel with passage of time and a change of a flow rate of the liquid passing through the fine tube with passage of time, and determining a viscosity of the liquid from the change of the internal pressure of the vessel and the change of the flow rate of the liquid. The pressure sensor is connected to the vessel by a device for piercing the other stopper and its output signals are fed to a computer through an A/D converter to calculate the viscosity of the liquid.
