203 -* At room temperature, containers of different materials, such as steel, glass, iron, ceramics, non-foamed plastics and other dense materials, have different detection blind areas and detection limit heights.
204 -* For containers of the same material at room temperature, the detection blind zone and detection limit height are also different for the thickness of the container.
205 -* When the detected liquid level exceeds the effective detection value of the sensor, and the liquid level of the liquid to be measured shakes or tilts, the detected liquid height is unstable.
