磁翻板液位计为何存在盲区，磁翻板液位计盲区影响液位测量吗？

       首先浮子本身是必须有长度的，即使再短也有长度，那么当液位为零或者接近零的时候，为了达到精确测量的效果，那么浮子肯定是以零液位起始上浮测量，所以盲区必须考虑到零液位以下浮子的长度。这就解释了为什么磁翻板液位计存在盲区，而这些盲区距离都是固定的，而且在下面两种情况下，有所不同计算液位：

       1、罐体的底端下面空间足以满足盲区部分的距离，那么这时候磁翻板液位计两法兰中心之间的距离就是满液位距离，不用考虑盲区。以上两种情况适应侧装磁翻板液位计，如果采用顶装磁翻板液位计，那么磁翻板液位计就不存在盲区问题了。

       2、如果磁翻板液位计罐体的底端下面空间足以满足盲区部分的距离，在设计选型的时候，法兰安装的时候肯定是在罐体底端与顶端之间，这时候计算液位的时候就要考虑盲区。
