<p>For obtaining accurate product weighing results in ships it is not sufficient to effect a correction of the weighing results by means of an accelerometer, which will only roughly compensate for the weighing errors due to the general movements in the sea. With the invention, corrections are also effected for errors from other marked sources of error, and only thereby it becomes possible to stake on a large-scale rearrangement of the fish industry from land-based to ship-based plants. Thus, corrections are made for errors due to tiltings of the ship and due to the mechanical noise produced by the engine of the ship or by operative implements on the ship; also, a calibration of the weighing system is carried out regularly by means of a calibration system which is effective even during movements in the sea. Moreover, the weighing system, which is passed by a weighing belt, is subdivided in three mutually independent weighing units (12), whereby usable weighing results are obtainable also by occurring weighing noise impacts, even if one of the weighings should be unacceptable.</p> |
