高铁对混凝土配方中液体外加剂的用量有时较少，精度要求还很高，要求控制在±1%，且要求每一盘的精度均需达标。本文设计了一套精确的外加剂计量系统，该系统包括粗计量管路和精计量管路，在两套管路上增加电动阀门，通过单片机控制阀门的开关，并在精计量管路上增加球阀，可手动调节精计量的落差值，使外加剂的计量精度达到设定要求。

The amount of high-speed rail on liquid admixtures for concrete in the formula is sometimes less, precision is high, demand controlled in ±1%, and the requirements of each disc precision required standards. This paper designs a set of exact additive measuring system, the system includes a rough measuring line and the precise metering pipeline, increase the electric valve in the two sets of lines, the switch control valve, ball valve and increase in precision measurement line, you can manually adjust the precision metering gap value, the measuring accuracy of admixture to set requirements.
