Definition:
A piezometer is a special tool used to measure the pressure of liquids or gases in a system. It helps scientists and engineers understand how much pressure is present, which is important in many fields such as hydrology, civil engineering, and environmental science.
In advanced studies, piezometers can also measure the pressure head, which is the height of a column of liquid that represents the fluid pressure at that point. This is useful in understanding groundwater flow and aquifer characteristics.
While the primary meaning relates to pressure measurement, the term "piezometer" does not have widely recognized alternative meanings outside of scientific contexts.
There are no specific idioms or phrasal verbs directly related to "piezometer," but you might encounter phrases like "measure up" or "gauge the pressure" in general contexts.
In summary, a piezometer is a measuring instrument used specifically for measuring pressure in liquids and gases.
