Abstract


With the continuous progress of science and technology , computer technology and microelectronic devices and more widely . Developed based on virtual instrument measurement accuracy , sensitivity , and reliability , as well as the degree of automation has been a qualitative leap, the virtual instrument has also been widely used in the flow measurement . China is a per capita resources are relatively scarce countries , the utilization efficiency of resources with the economic development of the increasingly high demand , and building a socialist harmonious society , indispensable to the accurate measurement of the flow , and thus test the quality of the flow test device and a higher degree of automation requirements . The degree of automation and reliability of existing static volumetric method verification device and dynamic volume is used to test the device is not vulnerable to the impact of the external environment , and the volume of traffic , less objective and accurate mass flow . I consulting the References at home and abroad on the basis of a detailed analysis and study of the verification principle of the flow test standard device proposed static quality law flow test system based on LabVIEW development platform . The technical innovation of the system has three main points . First, as the flow verification device , the accuracy is one of the most critical performance indicators . Of the static quality of law flow standard device to improve the analysis of a variety of factors that affect test accuracy ; Second, the design is based on the hardware and IPC PCI8606 data acquisition card connection circuit to achieve flowmeter certification process automation; constructed based on LabVIEW software platform , real-time control of the certification process and the test results in real-time display processing .
