Purging and Filling the Fluid Lines
Operation
2. Purge the low pressure Fluid Reservoir line of air and fill it with fluid.
If your triaxial cell doesn’t have a shut off valve for the upper pore pressure

(or a helper’s).
Turn the Permeability Output valve to the Open position.
As soon as the fluid entering the Fluid Reservoir becomes bubble-free, go
on to step 3.
