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。
Through the mathematical derivation of some basic laws of physics, various factors that affect the accuracy of the output water depth of the constant-flow bubble level sensor are revealed. In particular, the vertical elevation difference between the two ports of the trachea is the main factor affecting the accuracy of the output water depth. Non-gravitational acceleration or water density, and put forward a more accurate formula for calculating the output water depth.
