PORE WATER PRESSURE GAGE PERFORMANCE SPECIFICATIONS

A pore water pressure gage measures water pressures in soils or at the interface of the base of structure and natural rock. In soil this is referred to as pore water pressure. Beneath foundations of dams or other hydraulic structures it is referred to as uplift pressure. In neither case is it hydrostatic pressure, although this gage will also measure hydrostatic pressures when it is mounted in a body of water. It is an electrical transducer so constructed as to exclude mechanical pressure of soil grains bearing on each other, and to register only the water pressure between the soil grains. It converts this water pressure into an electrical signal which is carried by a cable to a convenient point for intermittent readings or continuous recordings of the pressures. It is designed to replace hydraulic piezometers which are difficult and expensive to install and to maintain.
