Apparatus for measuring flow of granular particles in conduit
First Claim
1. An apparatus for measuring at least one of flow rate or flow volume of material thru a material feed system, said apparatus comprising wall means providing a peripherally closed material passage means, said wall means providing an open, substantially unencumbered entry section and a downstream outlet section, said passage means having a generally vertically oriented flow axis, force reactive means rotatably mounted on said apparatus by connector means and extending within said outlet section for rotation therein about a rotational axis which is only generally coextensive with said flow axis, said force reactive means being provided with blade means having contact surface adapted for contact with a downwardly falling flowstream of said material within and thru said sections, said blade means having its contact surfaces free of any encumbrances and being adapted for rotation upon contact with said flowstream of material with said contact portions, signal means having signal generating and transmission structure associated with said force reactive means and responsive to the rotation of said force reactive means to provide material flow information to operating personnel.

Abstract
A blade device in a helix configuration suspended in a conduit means flowing full of granular materials such as crushed coal to rotate with the flow thus indicating by a turning or electrical output device both the rate and accumulated volume of flow of the granular material.
