An instrument for measuring pressure head in a conduit, tank or soil. It usually consists of a small pipe or tube tapped into the side of the container, with its inside end flush with, and normal to, the water face of the container, and connected with a manometer pressure gage, mercury or water column or other device for indicating pressure head.

An instrument to measure the pore water pressure.

A device for measuring pore water pressure (i.e. measuring the location of the water table). Some types of piezometers can also be used for collecting water samples. As a result, wells designed specifically for collecting water samples are often referred to, incorrectly, as piezometers.

A device used to measure ground-water pressure head at a point in the subsurface.

A groundwater monitoring well, sealed below the water table, installed for the specific purpose of determining either the elevation of the potentiometric surface or the physical, chemical, biological, or radiological properties of groundwater at some point within the saturated zone, or both.

Instrument for measuring pressure head; usually a small pipe tapped to the side of a closed or open conduit and connected to a pressure gauge or other device for showing pressure.

An extremely sensitive device which can measure subtle changes in air or water pressures in the subsurface.

A cased boring used to determine the level of ground water.

A nonpumping well, generally of small diameter, for measuring the elevation of a water table.

A small diameter tube installed into an aquifer that is used to measure the elevation of the watertable. A piezometer is slotted or screened at the bottom and sealed off above the slotted or screened section.

An instrument which measures hydraulic pressures in a conduit or hydraulic pressures within the fill of an earth dam or the abutment.

An instrument used to measure the elevation of the water table, i.e. how far below the surface groundwater is located.

An instrument for measuring pressure head; usually consisting of a small pipe tapped into the side of a closed or open conduit and flush with the inside; connected with a pressure gage, mercury, water column, or other device for indicating head.

a non-pumping well, generally of small diameter, that is used to measure the elevation of the water table.

A device that measures water pressure.

An instrument which measures hydraulic pressure head.

Vertical tube which is lower and connected to an aquifer, and its upper end located at or above the ground level used to determine the hydraulic head of that aquifer.

An instrument used to measure in situ pore pressures; may be an open standpipe or an enclosed electronic pressure transducer.

A device (tube or pipe) that allows one to determine the elevation of hydraulic head in an aquifer at a given point.

A groundwater well used for measuring pressure water elevation and water pressure.

A piezometer is a small diameter water well used to measure the hydraulic head of groundwater in aquifers. Similarly, it may also be a tube or manometer used to measure the pressure of a fluid at a specific location in a column.
