Coarse-grained Soil Permeability Test System HC-APC

System Description

The Coarse-Grained Soil Permeability Test System performs permeability tests on soil samples with a maximum particle size below 60 mm. The entire test process is automatically controlled. The hydraulic head is variable and adjustable. Parameters such as seepage discharge, permeability coefficient and hydraulic gradient are dynamically monitored in real time. The post-processing program automatically processes data and generates test results.

System Features

• Pneumatic proportional valve controls pressure and hydraulic head with large water flow capacity.

• Drainage is measured by electronic balance, with high-speed data acquisition and calculation.

Optional Upgrades

• High hydraulic head permeability test

• Volume-pressure controller (high-precision pressure control)
