- The LoadTrac II/FlowTrac II flow pump provides 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 cm/sec to 10-9 cm/sec.
- With the appropriate test cells, this one system can determine the permeability of some silty clays within minutes.
- The FlowTrac-II base unit includes a stepper motor, lead screw, pressure chamber and piston, pressure transducer, electronic controls and network communications.
- Versions of the unit are available with flow volumes of 250 cc and 750 cc.
- Flow rates can be set to any value between 0.000006 cc/sec. and 3.0 cc/sec.
- Flexible wall tests are run in a fully automated mode with three flow pumps and one LoadTrac-II; the FlowTrac-II’s controls cell pressure and flow of cell, bottom sample and top sample.
- This configuration allows great versatility to run fully automated permeability tests with isotropic, anisotropic or Ko consolidation.
- With the network communications module and the appropriate software, the entire test can be automatically controlled, data captured and displayed in real time, and test reports prepared on a PC.
- With GeoNet-LAN option, the test can be monitored and data reported from any PC located on a LAN to which the LoadTrac II/FlowTrac II system is connected.
- ® Control and editing software runs in Windows 2000, XP, Vista 7
