摘　　要：该文设计了一种可移动浮子流量计检定装置,该装置具有紧凑的结构、较强的灵活性和低廉的成本,将其与水平流向的水流量装置组合,可用于浮子流量计的检定,节省了引进专用浮子流量计检定装置所需的高额费用。通过理论分析和计算验证了设计方案的可行性,之后研制完成该装置,并进行了不确定度分析和流量稳定性试验,结果令人满意。This paper described a kind of movable liquid flowrate standard facility for float meter which has flow field,the float meters can be calibrated by the new device instead of dedicated facility. Then,the feasibility of the new device is verified by technical analysis and calculation. Finally,the device is installed. The uncertainty analysis and experiments for flowrate stability are finished,which is satisfactory.
