An apparatus and method for continuously measuring the settling rate, compaction, and clarity of a liquid. A liquid sample containing suspended solids is pumped into the bottom of a reservoir, and clarified liquid is allowed to overflow the top of the reservoir. Settling rate is measured by adjusting the pumping speed to maintain the interface between the clarified and unclarified portions of the suspension at a constant level. The slowing of this measured settling rate as solids accumulate in the test chamber is used to determine the percent ultimate compaction. Clarity is measured by allowing a sample to settle completely in the test chambers, at intervals that are provided by the need to occasionally remove the accumulated solids from the test chamber.
