gravimetry n
| gravimeter (gr-vm-tr) 1. An instrument used to measure variations in a gravitational field, typically by measuring the rate of acceleration of a falling body. Gravimeters are used to survey geological features with different densities beneath the Earth's surface, such as ore-laden rock or oil fields, that affect the local strength of gravity above them. 2. An instrument, such as a hydrometer, used to measure the specific gravity of a liquid or solid. |
