A method and apparatus for the automatic determination of a continuous bulk material through a continuous balance wherein a weighing vessel, an adjustable closure member movable in the weighing vessel for adjusting an outlet cross-section of the weighing vessel and an electronic weight difference measuring device are provided. The closure member provided in the outlet region of the vessel is so arranged that when the closure member is in the open operating position, there is a free mass flow in the weighing vessel and the bulk material flows freely and unhindered from the outlet of the weighing vessel. A control device is connected at its input to the weight measuring device and at its output to the adjustable closure member whereby a signal corresponding to the weight change in the weighing vessel per unit of time is produced, which is used for calculating the parameters of state of the bulk material flow.
