piezometer

A scientist carefully reads the pressure on the piezometer's dial.

Definition

Noun: 1. A scientific instrument for measuring pressure, particularly fluid pressure: A piezometer is a device used to gauge the pressure of a liquid or gas, often within a confined system like a pipe or the ground. It is especially associated with measuring high pressures. 2. A device for measuring compressibility: In some scientific contexts, a piezometer can be an instrument used to determine the change in volume of a substance under pressure.

Usage Examples
  • Noun:
    • Geologists installed a piezometer to monitor the water pressure in the aquifer.
    • The engineer checked the piezometer reading to ensure the pipeline pressure was within safe limits.
    • Accurate piezometer data is crucial for assessing slope stability.
Advanced Usage
  • "Piezometric head/surface": This refers to the level to which water will rise in a piezometer, representing the hydraulic potential or pressure at a specific point in a groundwater system.
    • The map of the piezometric surface shows the direction of groundwater flow.
Variants and Related Words
  • Piezometric (adjective): Relating to the measurement of pressure, especially groundwater pressure.
    • The piezometric data indicated a rising water table.
  • Piezometry (noun): The measurement of pressure, especially fluid pressure.
    • His research focuses on advances in piezometry.
Synonyms
  • Pressure gauge: A more general term for an instrument that measures pressure.
  • Manometer: An instrument for measuring pressure, typically using a column of liquid.
Notes on Meaning

The core meaning of "piezometer" is an instrument for measuring pressure. While the reference definition specifies "high pressures," its application in fields like hydrogeology often involves measuring natural groundwater pressures, which may not be exceptionally high. The defining characteristic is its function for pressure measurement, not exclusively the magnitude.
