초록

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.

대표
청구항

Apparatus for gravimetric metering of bulk material with a weighting container which is supported on at least one weighing cell connected to a weighing electronics and is connected by flexible connections to a bulk material feed line and a discharge line, wherein a pressure sensor is provided on the weighing container for detecting the pressure in the weighing container and the pressure sensor is connected to the weighing electronics for registering a weighing signal only when a limit pressure value is attained.
