Model EHOS-35 - Hydraulic Overflow Settlement Gage Brochure

EHOS-35 settlement gage is suitable for monitoring settlement or heave in embankments, embankment foundations and earth dams. It consists of a graduated standpipe and a sealed settlement cell with three accesses - first for an overflow pipe which is connected by a nylon tubing to the standpipe, second allows drainage of excess water from the cell and the third access allows atmospheric pressure to be maintained inside the cell. The cell is installed in soil fill and the standpipe on firm ground outside the structure. De-aired water is filled in the standpipe and tubing connecting it to the cell. Comparing the water level in the standpipe with earlier readings taken gives the settlement/heave to which the cell is subjected.
