摘　　要：基于虚拟仪器的流量测试仪是在传统流量测试仪的基础上,克服了传统流量测试仪的缺点,结合虚拟仪器技术开发出来的一种新型测试仪器。虚拟式流量测试仪以秦氏模型理论为基础,将虚拟仪器技术应用到流量测试领域,从硬件部分、软件部分、仪器面板3个方面详细介绍了流量测试仪的设计方法,将不同的流量测量方式模块化,用虚拟控件取代传统硬件,用虚拟仪器数字量的和显示取代传统流量测试仪的电路运算和表针显示,从而能实现流量的多线程远距离测试。The flowmeter based virtual instrument is a new test instrument, which has more advantages than the traditional flowmeter. This flowmeter is based on Qin's model. Apply to the flowrate measurement realm the virtual instrument technique. The design method has been introduced from hardware, software and panel, modelize the different flowrate measure way, with the virtual instrument's figural calculation and show to replace the traditional flowrate measurement, realize multi-threading long-distance flowrate measure easily.
