The FlowTrac II or III flow pumps provide a unique and versatile way to run flexible wall permeability tests on a wide variety of materials quickly and accurately. By adjusting the gradient or the flow rate across the sample, the system can measure permeabilities of cohesive soils varying from 10-4 to 10-9 cm/sec. With the appropriate test cells, this one system can determine the permeability of some silty clays within minutes.
