The piezometer
Did you know?
A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure (more precisely, the piezometric head) of groundwater at a specific point. A piezometer is designed to … Visa mer The first piezometers in geotechnical engineering were open wells or standpipes (sometimes called Casagrande piezometers) installed into an aquifer. A Casagrande piezometer will typically have a solid casing down … Visa mer • Rheometer • Tensiometer (soil science) Visa mer WebbPiezometers are used for measuring pore water pressures.
