A plunger viscometer with digital readout

Show affiliations


A description is given of a plunger viscometer which can be used to measure viscosities in the range 0.2kP to 1 MP with an accuracy of +or-1.5%. The viscometer consists of a plunger which is forced into a barrel containing the liquid sample by the action of a known mass. A ball-bearing bush is used to eliminate frictional effects from the system supporting the mass. The motion of the plunger is measured optically using a diffraction grating, and a digital measuring system is arranged to display the viscosity of the sample directly. The time necessary to take a measurement is in the range 20-1000 s. Typical sets of results are shown and a comparison is made with results obtained using suspended level capillary viscometers.
