Corrosion Resistant Piezometer (Vibrating Wire) VWP-3700 Series

Geosense VWP-3700 Series of Vibrating Wire piezometers are designed for measuring pore water pressure in harsh environments such as marine, tailings and mine leach heap applications.

Built on the same technology as our standard vibrating wire piezometer the external casings and most importantly the wetted surfaces are made from corrosions resistant titanium.

The measuring principle is the same as standard vibrating wire sensors and uses the well-proven method of converting fluid pressures on a sensitive diaphragm into a frequency signal.

Frequency signals are particularly suitable for the demanding environment of Civil Engineering applications, since the signals are capable of long transmission distances without degradation, tolerant of wet wiring conditions and resistant to external electrical noise. Options of both Polyurethane and Stainless-steel cables gives flexibility depending on the application.
