Abstract
Apparatus for producing an output signal or indication directly proportional to the density of one or more gases or liquids. A probe holds a vibrating vane immersed in a fluid. The probe is suspended from a pipeline flange by a boss that has upper and lower portions connected together by a thin annular cantilever-like disc in a plane transverse to the probe axis. The boss supports telescoped inner and outer cylinders along an axis normal to the probe axis. The cylinders have an interference fit. The outer cylinder has a uniform outside diameter but an unstressed inside diameter that increases in direct proportion to its length. The same is true of the outside diameter of the inner cylinder. The inner cylinder supports the vane. A seismic mass which vibrates the boss is unsupported except at one end.
