Piezometers
Piezometer Tips
A piezometer tip containing a porous element is connected via rigid tubing to ground level. Piezometric pressure at the tip is indicated by the head of water that develops inside the standpipe tubing. This water level is usually measured by lowering a dipmeter probe from ground level. Remote reading systems can also be supplied.
Porous HDPE or ceramic piezometer elements are available with an average pore diameter of approximately 60 microns and a permeability of approximately 3 x10-4m/sec. The tips are supplied with a .75" BSP threaded connector.
uPVC Piezometers
Lengths of standpipe tubing are supplied, complete with all necessary connectors. For borehole installations, it is normal to use rigid PVC. Piezometer pipe with an internal diameter of 19 mm is available in lengths of one and three metres. Each end is threaded .75" MBSP and supplied with one threaded socket for connection.

Galvanised Piezometers
Galvanised piezometer pipes are high strength steel. They are ideal for when the pipe must be physically driven or hammered into the ground.
