摘要
介绍了互相关法在时差法超声波流量计中的应用原理与数学模型,并基于Lab VIEW完成了超声波流速流量测量虚拟仪器系统设计。通过对模拟信号的仿真实验,验证了基于Lab VIEW的超声波流速流量测量仪的可行性,将虚拟仪器技术用于测量领域有着重要的意义。
The application of the principle and mathematical model of the cruss-correlation method in transit time ultrasonic meas- urement was introduced. The virtual instrument system for measuring ultrasonic velocity flow design was completed based on the Lab- VIEW. The feasibility of ultrasonic flow meter based on LabVIEW was verified by the simulation experiments of the analog signal. It is important significance that virtual instrument technology is used to measure in the field.
