A Viscosity cup is a simple gravity device that permits the timed flow of a Known volume of liquid passing through an orifice located at the bottom.
Code | LGL62 |
- Under ideal conditions, this rate of flow would be proportional to the Kinematic Viscosity (expressed in stokes and centistokes) that is dependent upon the specific gravity of the draining liquid.
- However, the conditions in a simple flow cup are seldom ideal for making true measurements of viscosity.
- It is important when using a Viscosity Cup and when retesting liquids that the temperature of the cup and the liquid is maintained, as ambient temperature makes a significant difference to viscosity and thus flow rate.
