FRF - Overburden Rig FRF - Liquid Permeability - Porosity @ stress
The rig is produced as a stand-alone unit and is ready for use. The following features are included
FRF - Overburden Rig
  • Hydraulic Confining Pressure system 0 - 700 bar (0 - 10,000 psi) using an air driven pump with a manual handle for fine adjustment of the confining pressure
  • Vacuum pump with liquid/gas membrane accumulator for easy loading and removal of core plugs from the core holder
  • Equipped with a selected number of RES-1250 bayonet quick release core holders, with electrical insulated end-pieces that allow FRF measurements to be made
  • The core holders are mounted on a panel for easy and safe operation
  • LCZ meter with digital display for multiple frequency FRF measurements
  • High accuracy liquid pump and three differential pressure transmitters for measuring individual liquid permeability vs. overburden pressure
  • Graded pipettes to measure individual pore volume (porosity) reduction vs. overburden pressure
  • The rig can be equipped with any number of core holders
  • A spares kit containing consumables and spare parts is also supplied
