A method for controlling or adjusting a metering organ (17) of a pneumatic dispensing machine having a transfer chamber (15) disposed downstream of the metering organ (17, 5) for transferring metered dispensing material to a conveyor line ( 6) a blower (4) for conveyor line request (6) with an airstream and distributor arranged downstream of the conveyor line (6). Calibration tests are performed, with the requested dosing body (17, 5) with a particular type of dispensing material having a predetermined operating parameter for a predetermined sampling period and the mass of dispensing material dosed during the calibration test being detected. gravimetrically, after, from the mass of distribution material obtained, in relation to the sampling period and the operating parameter of the dosing organ (17), a functional relationship between the operating parameter and the actual dosed mass current is calculated and the The metering device (17, 5) is controlled or regulated as a function of this functional relationship to a theoretical mass stream of dispensing material. the mass of dispensing material dosed during the calibration test is detected gravimetrically downstream of the dosing organ (17) and upstream or within the transfer chamber (14) after such dispensing material is transferred to the conveyor line ( 6) and taken out. A pneumatic dispensing machine with a weighing device (100) suitable for this purpose is also disclosed.processo para controle ou regulagem de um órgão dosador (17) de uma máquina distribuidora pneumática, que tem uma câmara de transferência (15) disposta a jusante do órgão dosador (17, 5) para transferência de material de distribuição dosado para uma linha transportadora (6), um ventilador (4) para solicitação da linha transportadora (6) com uma corrente de ar e órgãos distribuidores dispostos a jusante da linha transportadora (6). testes de calibração são feitos, com o órgão dosador (17, 5) solicitado com um determinado tipo de material de dist
