    摘要: An apparatus for measuring and a method for controlling the static charge developed by a flowable solid as it passes through a conduit. The flowable solid is conveyed through the conduit in such a manner that the powder develops a static charge due to the triboelectric effect as it moves against the conduit walls. The static charge on the solid is then measured using a static charge measuring device such as a Faraday drum or cage.
