ABSTRACT:
In a specific application the apparatus of this invention is used to measure the density of cement slurries employed in oil well cementing operations. As the slurry stream is pumped to the bore hole it is split into two parts. One part of the stream is sent through a curved conduit section which is positioned horizontally. The remaining part of the stream travels through a curved conduit section which is in a vertical position. The slurry flow in the vertical conduit sets up a hydrostatic pressure differential between the streams. This pressure difference, which is sensed by a differential pressure indicator, is read directly as units of density on the indicator scale.
