  • noun An instrument used to measure specific gravity.
  • noun An instrument used to measure variations in a gravitational field.

  • noun An instrument for determining the specific gravities of bodies, whether liquid or solid. See hydrometer.
  • noun 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.
  • noun 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 Wheeler, Sarah 1996

  • 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.

    Physical Review Focus - 2009

  • Using a sensitive gravimeter (as in reading microgals for use in geophysical exploration) one can take readings at several different heights above the floor.

  • An experiment probing for anomalous vertical gravity on Earth, which has already been performed by us, uses the highest-resolution atomic gravimeter so far.

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

  • 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 2009

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

  • Farther east along the ridge, Geoff Brown was fiddling with his gravity detector. Brown was a soft-spoken British geophysicist with long white hair and matching beard. He had brought with him an aluminum box the size of a car battery that he hoped could be used to track molten magma as it rose to the surface of a volcanic vent. The instrument detected infinitesimal changes in gravity, and because magma is lighter than solid rock, Brown was hoping to tell by testing the gravity field beneath Galeras if there was an eruption on the way . . .

    Joining Brown in his work and watching him inspect his gravity box were two Colombians . . .

    Geoff Brown sat his gravimeter on a makeshift stand, turned and twisted the dials, put his nose right up to the instrument, checked the readings, and took a few notes.

    Geoff Brown was next. The British scientist was anxious to get more familiar with his new gravity instrument and be sure it was working properly—he had been out working the previous day collecting gravity data from the center of Pasto to the top of Galeras, and the numbers his device had recorded had seemed suspect.

    "He told me that the gravity apparatus wasn't working. . . ."
    Id., ch. 10.
