简单介绍传统负迁移方法测量液位的原理,对比三门核电站核岛液位测量和常规岛液位测量实现,通过对差压变送器实际设置标定,提出并验证了智能差压变送器基于负迁移原理进行电流反向输出从而实现液位测量的方法。
Briefly introduce the principle of traditional negative transfer method to measure the liquid level, compare the nuclear island level measurement of Sanmen Nuclear Power Station with the conventional island liquid level measurement. Through the actual setting and calibration of the differential pressure transmitter, the intelligent differential pressure transmitter Based on the principle of negative transfer current reverse output in order to achieve the level measurement method.
