Piezometers
Multilevel Piezometer
The Model 4500MLP system overcomes the problems associated with the installation of multiple piezometers in a single drill hole. The 4500MLP is lowered into position and a spring loaded apparatus is actuated forcing specially configured piezometer filter elements into firm contact with the borehole walls. The borehole is then grouted from the bottom in one quick and simple operation.

¹Piezometers with a range of 350 kPa and higher are capable of reading negative pressures to −100 kPa. Please contact GEOKON for more information. Other ranges available on request.
*Please Note: All GEOKON vibrating wire piezometers include tripolar plasma surge arrestors to protect the sensor coils from possible lightning damage. Semiconductor piezometers are also available (see 3400 Series).
