Vibrating wire piezometer is a small-diameter observation for measuring the pressure of a fluid at a specific area in a column. The vibrating wire piezometer converts water pressure to a tensioned steel wire, a frequency signal, and an electromagnetic coil. Also, the vibrating wire piezometer is accurate and easy to read. The vibrating wire piezometer model, GV-2407, is widely spread for measuring ground water elevations and water pressure in road construction, pipe lines, and boreholes. Some features of the vibrating wire piezometer are for monitoring surface water run-off and encroachment of salt water into fresh water aquifers, and for controlling water pressure during consolidation by constant observation.
