摘　　要：设计了一种运用射频导纳原理的液位计,给出了射频导纳液位计的工作原理、电路设计以及无线通信接口的软硬件设计。所设计的液位计不仅改进了传统电容式液位计测量导电黏性液体液位时由于挂料而造成的虚假液位,而且能够明显减少恶劣的工业环境影响,具有高精度,适应范围广等特点。A kind of liquid level instnument based on RF principles was designed, and the working principle, electronic circuits, software and hardware of the instrument were given. The instrument improves traditional capacitive liquid level instrument in deceitful liq- uid level resulted in hang material, and reduces influence obviously in bad industry environment. The instrument has the characteristic of high accuracy, and can be used widely.
