Geomembrane Leak Assessment Shell Shaped Probe: 4,720,669

A leak assessment shell shaped probe for determining the size of a leak in a geomembrane liner by measuring the electric current density through the liner at locations suspected to contain a leaking penetration. By comparing the observed current flow through the liner, as measured by the assessment probe, with simulated current conducting contacts, the equivalent cross-sectional area of the leak perforation may be determined.
