ABSTRACT The present invention is a loss-in-weight weigh feeding system including means separate from the weighing means for detecting extraneous disturbances impinging on such systems and preventing them from adversely affecting the feed rate. The sys- tem includes a container for holding a substance to be fed, means for discharging the substance at a controllable feed rate, means for sensing the weight of the substance in the container and for producing a first signal responsive to the weight, means for generating a control signal in response to the first signal, means for controlling the discharging means in response to the control signal to maintain a desired feed rate, acceleration detection means for producing an acceleration signal in response to an acceleration of the weight sensing means, means for compar- ing the acceleration signal with a predetermined limit and means for inhibiting the action of the control signal on the control means when the comparison shows a difference beyond a predeter- mined size. The acceleration detection means may be an accelero- meter mounted on the loss-in-weight scale in order to detect ver- tical acceleration of the weighing system in either an upward or downward direction. The accelerometer output changes rapidly in response to the vertical acceleration, and the accelerometer out- put is detected and used to trigger a locking or other special control of the feed rate for the system.
