Abstract
The disclosure herein describes a unit used in an apparatus for measuring the viscosity of a fluid contained in a recipient; the unit includes a vertically displaceable piston at the upper end of which is provided a lifting plate while the lower end is equipped with a spherical head displaceably received in a cup immerged in the fluid. As the piston is lifted, fluid is drawn into the cup. After being raised, the piston is allowed to fall under gravity and the fluid in the cup is expelled through a small clearance between the spherical head and the inner cylindrical wall of the cup. The time required for the piston plate to contact and actuate a switch is proportional to the viscosity of the fluid.
