We get the same two questions almost every week about the CSC Bostwick Consistometer:

             1) What angle do I use to set it up?

             2) How do I level the Consistometer?

Principle of Operation

The principle of the CSC Bostwick Consistometer is based on the slump cone. In this procedure, a cone is filled with the material to be tested. It is then set on a level surface with the open area facing downward. The cone is pulled away and after a fixed time, the amount that the material slumped is measured.  The thicker the material, the less slumping occurs.

The answer, like most answers in the crazy measurement world, is, “it depends”. To find out what it depends on, we'll start with defining viscosity.

In our business, we use the word “sieve” to describe a piece of equipment that separates different sized particles  using a woven wire screen. To others, “sieve” can mean something very different.
