Casagrande and standpipe piezometers

Reference products codes: P101, P112, P112A, TCH, TFH
Casagrande filter unit is used to measure the water pressure in permeable soil. Filter unit is made in syntherised high density polyethylene.

It is available in different models to suite all the customer applications. Filter units have threaded cap joint with two 0.5″ twin tubes or with a 1.5″ single tube. Casagrande piezometers can be read manually with water level meter or automatically with transducer (removable transducervented pressure transducervibrating wire piezometer) connected to OMNIAlog datalogger.

Standpipe piezometers are used to monitor the ground water table. The standpipe filter unit consists of a slotted tube covered by geotechnical fabric for filtered water entry. Standpipe piezometers are mosly read manually with water level meter, but also automatic readings are allowed with vented pressure transducer or vibrating wire piezometer connected to OMNIAlog datalogger.

What is a piezometer, how it works, available technologies and models

With this video presentation, we would like to clarify the concept of “piezometer”, its various classifications (for example open circuit piezometer and closed circuit piezometer), the technologies available for monitoring piezometers (for example vibrating wire piezometers and piezo resistive) and the main models and solutions available.
