The instrument used for measuring depth of water table is known as

A. Lysimeter

B. Psycrometer

C. Piezometer

D. Evaporimeter

Answer: Option C

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.
