Gravity measuring apparatus is disclosed. In the preferred and illustrated embodiment, an apparatus utilizing a balanced container floating in a liquid rises and falls according to variations in gravity. Such variations in position are coupled to a measuring apparatus. In one embodiment, a horizontal beam pivotally mounted at one end and connected to the float as its center and nearly balanced about the pivot support at one end is deflected as the float rises and falls. Movement thereof is connected to a multiplier which enlarges the movement by some scale factor convenient to the circumstances in the range of 100 to about 1,000 to form an enlarged deflection of the multiplier adjacent to a motorized recorder, thereby forming a usable output indicia. The multiplier includes a pivotally mounted, upstanding framework having counterbalances so that it can stand vertically above its pivot point and further incorporates a laterally extending arm to which movements of the horizontal beam are coupled, the length of the arm from the pivot compared to the length of the multiplier providing the ratio of multiplication desired.
