ERI Fill Extensometer

The ERI is a fill extensometer designed to monitor longitudinal displacements between two points inside any type of man-made fill. It is usually installed horizontally in trenches. It may also be installed vertically to measure settlement at the point of contact with the foundation. It is also used to monitor the crest of earthfill dams to locate tension cracks.
