ABSTRACT:
In order to provide a method of gravimetric metering of bulk materials with a calibration facility thus achieving higher weighing accuracy there is proposed a method wherein the pressure in the weighing container is measured and the weighing signal is only transferred from the weighing electronics to be registered when a limit pressure value is attained, especially atmospheric pressure.
