Description
Durham Geo’s (DGSI) VW piezometers are primarily used to monitor water pressure but can also be used for water level monitoring. They provide both pressure and temperature readouts.
The bodies of the corrosion-resistant VW piezometers are manufactured of titanium while the polyethylene (PE) filters have a polyoxymethylene (POM) housing and the diaphragms are protected by a heat-bonded PTFE coating.
VW piezometers convert water pressure to a frequency signal through a diaphragm, tensioned steel wire, and electromagnetic coil. VW piezometers can be directly grouted-in using a bentonite-cement grout which simplifies the installation of multiple piezometers and can be installed with an inclinometer.
VW piezometers have a high resolution of 0.025% FS, high accuracy, rapid response times, and reliable signal transmission pressure and temperature readouts.
