Realization of Liquid Level Real-Time Control System Based on LabVIEW

This paper uses the virtual instrument as a developing method, LabVIEW as the developing environment and digital PED control algorithm to realize liquid level real-time control system. It also gives driving program interfaces, control arithmetic modules, specific program diagrams and main design points for key techniques such as parameter settings. Practical tests show that the system fully meets the various elements of the liquid control and realizes the real-time and rapid control requirements.
