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.

Durham Geo’s Low-Pressure VW Piezometers are specially designed to monitor small changes in pore-water pressure. Low-Pressure VW Piezometers can also be used, in conjunction with a barometer, to monitor water levels in open wells and weirs.

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.

VW piezometers are available in standard, corrosion-resistant, heavy-duty, and low-pressure models.

Custom cable lengths are available for all models.
