The standard method for measuring pore water pressure below the water table employs a piezometer, which measures the height to which a column of the liquid rises against gravity; i.e., the static pressure (or piezometric head) of groundwater at a specific depth. [6] Piezometers often employ electronic pressure transducers to provide

Pressure reference system (PRS) is an enhancement of the inertial reference system and attitude and heading reference system designed to provide position angles measurements which are stable in time and do not suffer from long term drift caused by the sensor imperfections. [1]
Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.
Literally "earth description"), a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. Technical geography as a distinct term in the English language within the discipline of geography dates back at least as far as 1749 to a book published by English printer Edward Cave at St John's Gate, Clerkenwell.
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
Telemetry is used to communicate the variable measurements of flow and tank level sensors detecting fluid movements and/or volumes by pneumatic, hydrostatic, or differential pressure; tank-confined ultrasonic, radar or Doppler effect echoes; or mechanical or magnetic sensors. [26] [27] [28
