The PW series vibrating wire piezometer is designed to measure pore water or other fluid pressure. It is used to monitor engineering works such as hydraulic structures, foundations, retaining walls, dams, embankments, excavations, tunnels, and waste repository sites. Thousands of PW piezometers have been installed in such works throughout the world.

Four models of PW piezometers are available:

The PWS is designed to be embedded in earth fills, at concrete/earth interfaces, or inserted into boreholes and small-diameter pipes. The end of the PWS is fitted with a high or low air entry filter, which protects the sensing element from solid particles, so that only fluid pressure is measured. The filter is easily removable for saturation.

The PWF is a thick-wall version of the PWS for use in direct burial applications.

The PWC is provided with a pipe thread adapter enabling the piezometer to be used as a pressure transducer.

The PWP is designed to be driven into unconsolidated fine grain materials such as sand, silt, or clay. The external housing is a thick-wall cylinder fitted with a conical shoe at one end, and an EW drill rod or standpipe thread adapter at the cable entry end.
