Abstract
The present invention is a method of measuring the total volume of solids in a suspension, comprising the steps of: establishing a potential across a predetermined spatial volume; passing a portion of the suspension through the predetermined spatial volume; substantially continuously measuring the potential across the predetermined spatial volume over a first predetermined period of time; comparing the measured potential with a baseline; and calculating the total volume of solids in the suspension as a function of a total absolute deviation of the measured potential from the baseline. The baseline is preferably a dynamic baseline, and is determined with reference to the starting point of a sharp rise in the measured potential.
