Abstract
The flow controller has a closure member of adjustable through-flow cross-section arranged on a storage bin or a gravity discharge pipe, and a regulating drive for regulating the through-flow cross-section. An inclined impact plate is secured on a first lever arm of a balance beam, in downwardly spaced relation to the closure member, so that the impact force on the plate, due to deflection thereby of the product falling through a given distance, is proportional to the actual value of the flow rate as expressed as quantity by weight per unit of time. The balance beam is pivotally connected intermediate its ends to a fixed frame and has at least one counter weight on a second lever arm, and an ajustable force-producing device acts on the balance beam in opposition to the impact force to regulate the through-flow cross-section. The deviation between the desired and actual values of the flow rate of the product, resulting from the interaction between the impact force and the force-producing device, is converted into a corresponding positive or negative pressure signal serving as a regulating signal for the regulating drive. An auxiliary beam is pivotally connected separately to the fixed frame, and the adjustable force-producing device loads the auxiliary beam. A supporting edge is mounted on the auxiliary beam for adjustment longitudinally thereof in engagement with the second lever arm of the balance beam to transmit to the latter a precisely balanced proportion of the load produced by the adjustable force-producing means, indicative of the desired value of flow rate of the product, and acting in opposition to the impact force. The adjustable force-producing device may comprise a weight movable longitudinally of the auxiliary beam in cooperation with a percentage scale, or a pressure responsive diaphragm element acting on the auxiliary beam through a lever arm extending therefrom, and the diaphragm element may be adjustable longitudinally of the auxiliary beam. Several such flow controllers may be individually adjustable with respect to different products and controlled from a central station.
