Abstract:
An apparatus for testing a porous medium is provided. The apparatus includes a liquid processing subsystem and a liquid weighing subsystem. The liquid processing subsystem is interfaced with the medium in a manner that establishes liquid contact there-between. The liquid processing and liquid weighing subsystems are sealably interconnected via an interconnecting liquid tube. The liquid weighing subsystem stores a liquid which flows therefrom, through the tube, through the liquid processing subsystem, and into the medium until it is saturated with the liquid. The liquid weighing subsystem automatically measures the weight of the liquid stored therein on an ongoing basis and uses these measurements to determine one or more hydraulic properties of the medium.
