Vibrating Wire Piezometer

Vibrating Wire Piezometer

The Vibrating Wire Piezometer (VWP) is the industry standard in pore pressure monitoring. More reliable than a strain-gauge or 4-20 mA piezometer, the Vibrating Wire Piezometer can be used for static water level measurement, tailings dam monitoring, mine dewatering, aquifer monitoring and many other applications.  Constructed from high-quality 316 stainless steel, the VWP is capable of performing with long cable runs with an operation longevity for many years. The HMA Geotechnical Vibrating Wire Piezometer is compatible with most commercially available readouts and dataloggers.
