  • Flowmeter for object-bearing liquids
    Patent number: 5311781
    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.

  • Explosion-proof flow sampling apparatus
    Patent number: 4037472
    Abstract: An apparatus for collecting samples of water from open flows is disclosed. The apparatus includes a controller, a quantimetric chamber and storage means, and provides for automatic collection and storage of liquid samples. The entire device is pneumatically operated and therefore suitable for use in explosive atmospheres.
