Rowe Consolidation

FLOWTRAC-II

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

The FlowTrac II system for consolidation testing using the hydraulic Rowe-type consolidation cell automates an entire consolidation test. Once a sample is placed into the Rowe cell, the test condi-tions programmed and the test started, FlowTrac II performs the entire test without intervention. The system automatically initializes, back pressure saturates, and consolidate incrementally by using conditions specified by the user. A typical incremental consolidation test can be completed in 36 to 48 hours on most materials.

This system may be programmed with a series of steps. At the end of each step, the system will automatically move to the next step based on the computer deter-mining that the specified conditions for completion of consolidation for the previous step are reached. Any load-unload-reload pattern may be specified. Flow-Trac II consolidation system lets you complete tests faster with less man time. An entire test can usually be completed in 12 to 24 hours. Complete detailed tabular and graphical reports can be prepared in minutes after completing the test using a PC and a printer or plotter.
