| Abstract: | This paper introduced the structure and measuring principle of weighing control system of SCHENCK Co., Germany widely used in polyester plant and analyzed the factors that affect measuring precision. Countermeasures had been put forward in light of the problems happened during operation, such as actual feed flow falling short of set value, system shutdown because of excessive instantaneous flow and so on. |
