Abstract
A viscoelastometer for measuring and displaying a viscoelastic effect in a liquid such as water, oils, paints, blood or thickened liquids or suspensions including types commonly used as foods or pharmaceuticals as a reproducible force time signature. The viscoelastometer comprises a rigid member suspended from the free end of a resilient, deflectable cantilever which extends from a rigid support, a liquid sample cup associated with a pneumatic cylinder for moving the sample cup at a selected rate between an upper position at which the rigid member is immersed to a predetermined depth in the liquid and a lower position at or before which occurs relaxation and separation of a filament of the liquid which forms between the rigid member and the surface of the liquid during downward movement of the sample cup, strain gauges associated with a portion of the cantilever intermediate the rigid member and the rigid support, and a display associated with the strain guages to display a quantitatively reproducible force time signature representative of the viscosity and elasticity of the liquid as a function of the sensed strain imparted to the cantilever as the sample cup is moved between the upper and lower positions.
