piezometer
/ˌpʌɪɪˈzɒmɪtə
/noun
An instrument for measuring the pressure of a liquid or gas, or something related to pressure (such as the compressibility of liquid). Piezometers are often placed in boreholes to monitor the pressure or depth of groundwater.Horizontal movement is measured by inclinometers, and multiple-point vibrating-wire piezometers provide information on groundwater pressure....
- The instrumentation includes various gauges embedded in the dam structure or installed around the dam body, such as uplift pressure cells, thermometers, piezometers, stress and strain meters, and coordimeters.
- Two piezometers were installed to measure groundwater levels.
Origin
Early 19th century: from Greek piezein 'press, squeeze' + -meter.
