Flowmeter automatic verification system based on virtual instrument

To improve the automation level of flow measurement device in the lab, enhance the ability of experiment, and make the efficiency of using these equipments higher, a remote measurement and control system for flow meter verification which based on Labview and PLC is designed in this paper. This system can realize volume and master meter method for verification. Experimental results show that it is easy to build a remote measurement and control system based on virtual instrument. By using this system, the teaching and scientific research value can be full used, and the reasonable allocation of limited resources can be achieved.
