Abstract
A flow rate sensor particularly for use with pelleted, granular, or powdered materials having a support and a pivotal member which is pivotally mounted to the support for pivotal movement about a generally vertical axis. An arm extends from the pivotal member and a deflection plate is mounted at the extended end of the arm for impingement of a vertical flow of material thereagainst such that the deflection plate resolves the vertical flow of material into a horizontal force component producing horizontal deflection of the deflection plate and angular deflection of the pivotal member about the pivotal axis. The pivotal mounting for the pivotal member includes a thin shim secured to the pivotal member and support providing flexing of the shim over a section thereof located between the pivotal member and the support. Also included is a transducer for translating the degree of deflection of the pivotal member into signals indicating the flow rate of the material, and a damper for dampening oscillation of the pivotal member.
