Abstract
A method and apparatus for the continuous determination of the flow rate and/or total weight of dry particles, measuring the speed imposed to a movable member by dry particles falling thereon.
Claims8
An apparatus for measuring at least one of weight flow rate and total weight of dry particles, comprising:
- means for channeling dry particles on a substantially vertical flow;
- a rotating member mounted for rotation around a substantially horizontal axis and positioned relative to said means for channeling so that said substantially vertical flow causes rotation of said rotating member around said axis in one direction;
- means for applying a braking force to said rotating member against rotation in said one direction;
- and
- means for correlating speed of rotation of said rotating member and said braking force to determine said at least one of weight flow rate and total weight of said dry particles.

A method for measuring at least one of weight flow rate and total weight of dry particles, comprising the steps of:
- providing said dry particles in a substantially vertical flow;
- positioning a rotatable member in said substantially vertical flow and mounted for rotation around a substantially horizontal axis so as to cause rotation of said rotatable member in one direction;
- applying a braking force to said rotating member against said rotation in said one direction;
- and
- determining said at least one of weight flow rate and total weight of said dry particles from speed of rotation of said rotating member and said braking force.
