PCT No. PCT/SE92/00324 Sec. 371 Date Dec. 3, 1993 Sec. 102(e) Date Dec. 3, 1993 PCT Filed May 18, 1992 PCT Pub. No. WO92/21009 PCT Pub. Date Nov. 26, 1992A method of determining a load measurement value in dynamic weighing of an object passing over a weighing platform supported by load-sensing means generating a load-dependent weighing signal (S) which rises from a basic level to a peak level, to subsequently fall to the basic level. An at least approximative signal peak value (Speak) is determined as representing the weighed load. The weighing signal is integrated at least during a time interval (t1-t5) about the point where the signal peak value is determined in order to produce a summation result, the time interval being recorded as a measurement time factor (M). Further, a form factor (F) for the weighing signal is calculated in the form of the ratio of the summation result, i.e., the integrated area under the weighing signal (S) for the time interval (t1-t5), to a corresponding rectangular area that would be obtained in static weighing, i.e., the product of a peak value and the above time interval. Finally, the load measurement value is determined as the above-signal peak value with a resolution depending on a quality factor Q=FxMxk, wherein k is a factor chosen while taking into consideration the weighing conditions.
