摘　　要：分析测量高加水位的液位开关和差压式水位计的原理及其各自的优缺点,提出了消除差压式水位计测量误差的方法,采用差压式水位计的信号作高加水位的保护信号,以完善高加水位的保护控制逻辑,同时也给高加水位保护逻辑的完善提供一种新的思路。The measure theory of level-switch of HPH water level and the differential pressure water level gauge are analyzed and their advantage and disadvantage are compared. The way to eliminate measurement deviation of HPH water level gauge is presented, using the signal of differential pressure water level gauge as the protection signal of HPH to improve the protection control logic.
