Home Test Methods Soil Testing Constant Rate of Flow Permeability Soil Test Equipment Constant Rate of Flow Permeability Soil Test Equipment The constant rate of flow test simply maintains a constant base pressure whilst applying a constant flow through the top of the specimen. A maximum hydraulic gradient can be set which will pause the rate of flow if the pressure differential between the top and the base of the sample gets too large. Please note: Some apparatus may require additional components or software modules to perform certain tests. The following soil test equipment can perform the Constant Rate of Flow Permeability soil test:- Resonant Column Apparatus (Hardin Type) for constant rate of flow permeability soil test Hydraulic Load Frames for Rock for constant rate of flow permeability soil test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for constant rate of flow permeability soil test Environmental Triaxial Testing System for constant rate of flow permeability soil test Environmental Triaxial Automated System for constant rate of flow permeability soil test GDS Small-Strain Hollow Cylinder Apparatus for constant rate of flow permeability soil test Resonant Column Apparatus (Stokoe Type) for constant rate of flow permeability soil test GDS True Triaxial Apparatus for constant rate of flow permeability soil test GDS Large Diameter Cyclic Triaxial Testing System for constant rate of flow permeability soil test Advanced Dynamic Triaxial Testing System for constant rate of flow permeability soil test GDS Enterprise Level Dynamic Triaxial Testing System for constant rate of flow permeability soil test Hydraulic Load Frames for Soil for constant rate of flow permeability soil test Virtual Infinite Stiffness Load Frames for constant rate of flow permeability soil test Triaxial Automated System (Load Frame type) for constant rate of flow permeability soil test Triaxial Testing System (Automated Stress Path type) for constant rate of flow permeability soil test Triaxial Cells for constant rate of flow permeability soil test Infinite Volume Controller for constant rate of flow permeability soil test High Pressure Volume Controllers 8MPa to 100MPa for constant rate of flow permeability soil test Advanced Pressure Volume Controller for constant rate of flow permeability soil test Enterprise Level Pressure Volume Controller for constant rate of flow permeability soil test Standard Pressure Volume Controller for constant rate of flow permeability soil test
