Abstract:
An apparatus for on-line monitoring of a liquid density comprising:an upright, cylindrical housing that is substantially transparent and fluid-tight defining a cavity therein, a liquid inlet tube in fluid communication with a lower portion of said cavity, a liquid outlet tube in fluid communication with a middle portion of said cavity, a stabilizing plate positioned at said lower portion of said cavity in said housing with said liquid inlet tube connected therethrough for feeding a liquid downwardly toward a bottom of said cylindrical housing, said stabilizing plate partially separates said lower portion of cavity from said cavity, a quantity of liquid in said cavity having a top level substantially at the same elevation of said liquid outlet tube, a density indicator constructed of a float and a measuring stick integrally joined together such that when the float is submerged in said liquid, the measuring stick is emerged above said top level of the liquid, and at least two positioning guides fixedly attached to said cylindrical housing adapted for guiding said measuring stick in a substantially upright position.
