  • n. An instrument for ascertaining the specific gravity of bodies.

from The Century Dictionary and Cyclopedia

  • n. An instrument for determining the specific gravities of bodies, whether liquid or solid. See hydrometer.
  • n. An instrument for measuring the force of gravity against some elastic force. There have been many attempts to construct such instruments, but none has been successful.
  • n. Specifically, a copper vessel of one cubic foot capacity, with a heavy plate-glass cover, used in determining the density of large-grained gunpowder inclusive of the vacant spaces between its grains. See gravimetric density of gunpowder, under density.

  • It was called a gravimeter, and it sat in a huge glass-and-wood cabinet like the ones you see at the Smithsonian or the British Museum.

    Terra Incognita

  • The experiment does not yet yield a gravity measurement of great accuracy, but the researchers believe the technique could lead to a workable "gravimeter" small enough to use in navigation systems that depend on acceleration measurements.

  • Ray and his team were not just taking pictures they were using all kinds of instruments including a magnetometer, gravimeter, microdensitometer, spectrometer etc.

    A Contactee Far Ahead of the Times

  • But you can get it strange wrathfully the teasingly undismayed all terrain truck deterrent that premier it, and we gave him the web gravimeter.

    Rational Review

  • If heavy element deposits are hidden underneath, the gravimeter will react promptly by showing strong fluctuations in the local gravity field. "
