FIELD: invention may be used in semiconductor, food, pharmaceutical and other industries for contactless determination of weight of piece articles presented in the form of thin plates or made from material of low specific density. SUBSTANCE: in compliance with method article is positioned above supporting platform on vertical air currents. Weight is determined by excessive air pressure in pneumatic system with preset height of currents by means of formula G = 2•π•P•r•(r-0,05•x)•W, where G is weight of article; Pis excessive pressure in pneumatic system; ris radius of air current; x is height of current; N is number of currents. EFFECT: increased measurement precision. |
