针对LF13-2DPP平台现场液位检测使用的磁浮子液位计多次出现浮子卡滞、浮子穿孔进水等现象,导致生产工艺波动较大,多次造成生产关断的现状,提出了在保留现有磁浮子液位计的基础上,增加双法兰差压液位计作为参考及备用控制回路,实现了控制的无扰动切换,实际投入使用后取得了良好的效果。 Aiming at the phenomenon that the float level gauge of the float level gauge used in the on-the-spot level detection of the LF13-2DPP platform appears floats and perforation of the float, the production process fluctuates greatly and the shut-down of the production is caused several times. Based on the existing magnetic floater level gauge, the double flange differential pressure level gauge is added as a reference and standby control loop to achieve the control of the disturbance-free switchover, and the good effect has been achieved after being put into practical use.
