Abstract
A fluid density measurement device includes a float ( ) and a weight ( ), each mounted on links ( ) for essentially vertical movement. A crank ( ) is mounted above the float and weight and is connected to them,by a float link ( ) and a counterweight link ( ) to convert the forces from the float and the forces from the weight to rotational forces on the crank acting in opposite directions. The position adopted by the crank will be dependent upon the density of the fluid in which the instrument is immersed. The links ( ) are arranged so that a good approximation to straight line motion is obtained at the centre of the float and the weight.
