Abstract
The flowmeter of this invention computes the volumetric flow rate of a liquid by measuring the changing positions of objects carried in the flow. This information can be combined with data describing the size, shape and fraction of filling of the conduit. By measuring displacement instead of velocity, accurate measurements of liquid movement can be obtained even when flows are moving very slowly, or not at all.
