Master control a control section in a typical paralleling system that provides total system metering and the interface point between the paralleling system and the facility.

主控制主控制是典型的并联系统计量控制设备，也是并联系统与用电设施之间的接口。

So a study on mechatronics of the precise metering feeder of powder and control system is necessary in actually.

因此将机电相结合，研究并设计出一种粉体的精密计量装置与控制系统具有极高的现实意义。

youdao

This device is easy to control, simple in maintenance and low in cost; functionally it can substitute for metering pumps and electromagnetic flow meters used in system.

该装置易于控制，维护维修简单、成本低廉，功能上能取代系统中使用的计量泵和电磁流量计。
