摘要
为多圈环形管流量计设计了一个多点差压信号的自动数据采集系统,可用于测量和记录环形管不同位置上差压测点的数据,进而确定各测点位置差压信号与总流量之间的关系,以及研究环形管流量系数的变化趋势.该数据采集系统具有测量精度高,采集速度快,数据实时保存等特点.
An automated data acquisition system of muhipoint differential pressure signals has been designed for the multi-circle pipe flow meter. It is used： to measure and record the differential pressure signals at different positions of the multi-circle pipe, to find the relation between total flow and the differential pressure signals at different measuring positions, and to research the variation tendencies of the flow coefficient of the multi-circle pipe. The data acquisition system has many features such as high precision, fast collecting rate and data stored in real-time etc.
