The Computer Measuring and Controlling System for the Plugging Meter of the Mobile Sodium Purification Device

The plugging meter of mobile sodium purification device is the special equipment for on-line monitoring the plugging temperature, and according to which to calculate oxygen content in the sodium. This paper introduced the working principle of the test sodium loop, plugging meter and the computer measuring and controlling system. The core of the system was a data acquisition card, and using pure PID control algorithm to complete the whole measuring process of the plugging temperature and solving the plugging temperature by curve fitting method. The system could also display in real time the change curve of flow and temperature in plugging area, and record the test data simultaneously. After multiple debugging and trial running, the system was at good performance which laid foundation on debugging and running for other plugging meters.
