摘　　要：水流量计在测试过程中通常采用一表一侧的单一性现场测试方式,存在检测效率低下、现场校验精确性不高等问题。因此,为实现其在线校验和远程监控,本文提出一种基于虚拟仪器技术的移动式水流量计在线校准系统,并进行实验验证。试验表明:该系统可将校准精度提高至96%,且稳定性提高了23%,可为后续研究奠定技术基础。In the process of testing,the water flowmeter usually adopts a single field test on one side of the table,but there are problems such as low detection efficiency and low accuracy of field verification.Therefore,in order to realize its online calibration and remote monitoring,this paper proposes an online calibration system for mobile water flowmeter based on virtual instrument technology,and carries out experimental verification.The test results show that the system can improve the calibration accuracy to 96%and the stability by 23%,which can lay a technical foundation for the follow-up research.
