Abstract
An on-line method for consistency (percent solids by weight) testing of slurries. An aqueous slurry is deaerated and subjected to a nuclear density (gamma radiation) gauge which is oriented to irradiate the slurry along the axis of a pipe section. Pipe elbows at the ends of the test pipe section permit simple attachment of the nuclear density gauge so that the axially-aligned radiation can be used with various pipe lengths. The electrical output of the gauge is read to immediately furnish a real time reading of consistency.
