Solution (By Examveda Team)

Piezometer is the device used to measure the depth of the water table as it estimates the pressure of underground water. It converts water pressure to a frequency signal via a diaphragm and a tensioned steel wire. A change in pressure on the diaphragm causes a change in the tension of the wire hence, the pressure or depth of the water can be calculated.
