| Abstract: | 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. |
