An apparatus and method are disclosed for determining the amount of material remaining in a dry silo 1 that is in communication with a mixing device 2. The apparatus comprises a control unit, a first sensing means operable to sense the position of an outlet valve of the silo, and a second sensing means operable to measure the current of a mixing screw motor of a mixing device associated with the silo, wherein the sensing means are in communication with the control unit, and wherein the control unit is configured to monitor measurements of electrical current from the mixing screw motor to determine the operational status of the mixing screw and is configured to measure the run time of the mixing screw motor at the measured electrical current in order to measure the amount of material passed through the mixing screw. |
