The hydraulic consolidation system (Rowe Cell system) is used because of its multiple drainage (up to eight conditions) options as well as the capability to test large diameter samples using water pressure on a flexible diaphragm. Furthermore, free strain and equal strain can be applied on the top of the sample through a flexible platen or a rigid one.

The FlowTrac flow pumps automate the entire consolidation test using conditions specified, with typical completion in 24 to 48 hours. The system automatically initializes, back pressure saturates, and consolidates incrementally without intervention by the user.
