摘　　要：通过对一些基本的物理学定律的数学推导,揭示了影响恒流式气泡液位传感器输出水深精度的各种因素,特别指出了气管两端口竖直高差是影响输出水深精度的主要因素,而非重力加速度或水密度,并提出了更为精确的输出水深计算公式。With math derivation based on some basic physics law,the various factors that affected the precision of the water depth of constant flow bubbler stage sensor output are uncovered,especially pointed out the stage precision was mainly affected by the vertical drop between two ends of the tube,but not the gravity acceleration or water density. A more accurate formula for calculating the water depth of constant flow bubbler stage sensor output is given.
