Many different types of piezometer are used during geotechnical monitoring and instrumentation. Piezometer installation is done accurately and with precision to avoid future disruption in the readings.
Piezometers are geotechnical instruments used in the measurement of pore water pressure in soil, dams, concrete structures, etc.Many different types of piezometer are used during geotechnical monitoring and instrumentation. Piezometer installation is done accurately and with precision to avoid future disruption in the readings.
Encardio-rite Model EPP-30V is recommended for installing in an embankment.The following steps are followed for the VW piezometer installation procedure.
NOTE: Make sure to record the initial temperature and reading with the readout unit as it will form the zero reading for the piezometer. Also, note the barometric pressure at the time of initial reading.

NOTE: Piezometer cable should be properly guided through the drill rods & the piezometer or its cable should never be allowed to rotate on inside the rods. Care should also be taken to ensure that the drill rod edges do not cut into the cable sheathing while installing.
NOTE: Make sure that the piezometer cable is inserted through the holes of the adaptor rod, coupling, and the first drill rod in that sequence, before fixing it. It is important to keep the piezometer fixed while rotating the adaptor rod, coupling or the drill rods, as any rotation will get damaged.
NOTE: Great care should be taken while unscrewing the drill rods from the rod adaptor as the piezometer cable running inside the drill rods do not get damaged due to abrasion from the drill rod surface or edges.
