ABSTRACT:
A density measuring device having a float with a marker provided therein that is connected by a pair of springs to each of the two supports which are on opposite sides of the float along a guide. A sonic waveguide arrangement is provided extending along this guide past at least one of the supports which can measure the relative positions of the float to thereby determine the effective buoyant force on the float and so the density of the fluid in which the float is submerged. Use of a further float permits determining fluid levels.
