摘要
研究了应用流量计测量流量过程的数据采集、信号处理、标定及动态测试等技术,建立了基于Labview软件、采集卡及测试实验台的流量测试系统,实现了流量的自动、准确测量。并采用一种简单、有效的方法验证了椭圆流量计动态测量的局限性,为研发流体自动测试系统提供了有效的技术支持。
A research on the technology of DAQ （data acquisition）, signal processing, flow - meter calibration and dynamic test in the process of flux testing with flow - meter was carried out. A flux - testing system based on the software of Labview, A/D cards and testing stand was established to realize automatic and exact measurement of flux, and a simple and available method was applied to validate the limit of flow - meter in dynamic testing occasion. Thus, the result of above provides an effective technical support for developing auto test system of liquid.
