WebGeotechnical Monitoring Products & Services Soil Instruments WebVibrating Wire Piezometers. A vibrating wire piezometer, Figure 1, works on the same principle as tuning a guitar or piano (SINCO, 1994). A steel wire is stretched over a distance. The wire is set to vibrating by “plucking” it with an electromagnetic field. The natural frequency of the wire is a function of the tension in it. By reducing or ...
