Piezometers
Vibrating Wire Type Piezometer
The Vibrating Wire Type Piezometer is a precision instrument designed to measure pore water pressure in soil, rock, or concrete for monitoring groundwater levels, embankment stability, and seepage in dams and foundations.
Features
- The vibrating wire technology ensures precise and stable measurements, even in harsh environmental conditions.
- Made from high-grade stainless steel, the piezometer is corrosion-resistant and suitable for long-term monitoring.
- An integrated thermistor allows for simultaneous measurement of temperature, aiding in accurate data interpretation.
- Compatible with various dataloggers for easy and reliable data acquisition.

Casagrande Stand Open Stand Pipe Piezometers
It is used to measure pore water pressure in soil and rock formations. The system features a cylindrical ceramic or plastic filter element with either low or high air entry value, sealed at one end with a PVC, brass, or rubber stopper. The opposite end includes a PVC, brass, or rubber bushing to allow easy assembly with PVC pipes.
The depth of the piezometer tip is adjusted by connecting additional PVC pipes and couplings. At the surface, a protective PVC or GI pipe with a cap is used to shield the system from dust and external elements, particularly in open-loop systems designed for level measurement.
Simple yet effective, this device consists of a perforated pipe installed in a borehole, allowing water to enter and rise within the pipe to the level corresponding to the groundwater pressure. Water level is recorded through a Water Level Indicator.
