| 摘要 |
A densitometer apparatus is disclosed which is adapted for accurately measuring the density of a liquid and particularly of a slurry flowing in a pipeline. The apparatus includes a pipe section which is coupled to the rest of the pipeline by substantially friction and resistance free hydrostatic bearings in such a manner that the pipe section is able to move, at least to a limited extent, in a direction parallel with the earth's gravitational field. The weight of the pipe section is accurately measured together with the weight of the slurry or liquid contained therein by load cells, strain gauges or the like. A unique flow velocity meter is also disclosed. The flow velocity meter includes two densitometers positioned at a predetermined distance from one another on the pipeline, and measures the time it takes a density fluctuation pattern to travel from one densitometer to another. |
