单词 piezometer
释义
piezometer

Chemical Engineering
  • An instrument used to determine the static pressure of a liquid such as in a pipe. It consists of a vertical tube in which the vertical elevation of the liquid is a measure of the pressure. Piezoelectric pressure sensors are used to measure the pressure and convert it to an electrical signal. There are various types commonly used including pneumatic, strain gauges, and vibrating wire sensors. The data is then captured on a data logger.


Geology and Earth Sciences
