    • A weighing vibratory apparatus and method. In one embodiment, an infeed vibratory conveyor element feeds a bulk product to a weighing vibratory conveyor element. In another embodiment, bulk product is fed directly to a weighing vibratory conveyor element and flow rate is determined by measuring the loss of weight therefrom. The weighing vibratory conveyor element includes a weight measuring apparatus that weighs the product at the same time that the product is being dispensed through vibrations. The weight measuring apparatus may be coupled to the vibratory conveyor element through damping mechanisms. An electrical signal output of the weight measuring apparatus may be low-pass filtered to provide an improved signal for feeding to a controller for controlling the flow rate.
    • 称重振动装置及方法。 在一个实施例中,进料振动输送机元件将批量产品送入称重振动输送机元件。 在另一个实施例中,大量产品直接供给到称重振动输送机元件,并且通过测量其重量损失来确定流速。 称重振动输送机元件包括重量测量装置,其通过振动在产品分配的同时对产品进行称重。 重量测量装置可以通过阻尼机构联接到振动输送机元件。 重量测量装置的电信号输出可以被低通滤波以提供改进的信号,以供给控制器来控制流量。
