How does a vibrating wire piezometer work
WebVibrating Wire Piezometers contain a high tensile steel wire with a fixed anchor at one end and are attached to a diaphragm in contact with water pressure at the other end. The wire is electrically plucked, with the resonant frequency of vibration proportional to the tension in the wire. This frequency induces an alternating WebJan 30, 2024 · When working with vibrating wire piezometer installation, the initial reading (offset) of the frequency displayed on the portable readout unit should be stable.
