PVT Membrane type piezometer
The GEOTECH PVT membrane piezometer is suitable for measuring the pore water pressure where an open standpipe solution is not suitable, e.g. in dense soils or where artesian water pressure is present.
Lower the sensor unit through the connected pipe and let its needle penetrate the filter tip membrane to measure the pore water pressure.
The membrane type filter tip is available in different materials and is delivered with a connection pipe with standard 1” water pipe threads. When installed, the built in membrane will prevent the water from rising up through the pipe.
PVT Needle probe with data logger
Lower the probe through the piezometer pipe. The needle of the probe will penetrate the membrane of the permanently passive filter tip. The probe can be permanently connected or used for reading real-time values upon visit.
Connect your computer via the USB-crocodile clip for monitoring the pore water pressure, starting/stopping logging, setting logging intervals and uploading the log file. The probe can alternatively be connected to a local network with a telematics unit for remote monitoring and/or instant alarms upon critical values.

Piezometer
The pore water pressure can be of great importance for soil properties. This is not least important for the stability of slopes and for protection of roads, bridges and buildings. The GEOTECH PVT direct push piezometers have laser-trimmed ceramic sensors and are optionally available with a built-in data loggers. This sensor type is very stable over time, making it the perfect choice for long-time projects and permanent installations.
We also offer solutions with open standpipe or membrane filter tips. Geotech’s telematics solutions gives you access to the data wherever you are.
Direct push piezometer with memory
The GEOTECH PVT direct push piezometer with memory has a built-in datalogger and operates without the need for additional battery or any other external equipment.
Direct push piezometer
The GEOTECH PVT direct push piezometer has a laser-trimmed ceramic sensor. Connect your computer for instant reading of pore water pressure. Solutions for remote reading are available.
Membrane piezometer
The GEOTECH PVT membrane piezometer is suitable for measuring the pore water pressure where an open standpipe solution is not suitable, e.g. in dense soils or where artesian water pressure is present.
Open standpipe piezometer
The GEOTECH OPEN STANDPIPE piezometer comes with a connection for 1” standard water pipes. It is optionally available with hose connection. We offer a wide range of water level meters.
Telematics solutions for remote reading
The GEOTECH PVT REMOTE GATEWAY provides the capacity to remotely monitor data from of up to eight GEOTECH PVT piezometers.
