1、 Recommended distance
1. From the wall to the outer wall of the short pipe installation
2. At a distance of 1/6 of the tank diameter from the tank wall, the minimum distance is 200mm
3. Cannot be installed above the feeding port

2、 Installation precautions
1. The antenna is parallel to the measurement slot wall, which facilitates the propagation of microwaves.
2. The distance between the installation position and the groove wall should be greater than 30cm to avoid mistaking false signals on the groove wall for echo signals.
3. Try to avoid interference sources such as feeding areas and mixers, so that there are no fixed objects within the beam range, and improve the reliability of the signal.
4. The diameter of the connecting pipe should be less than or equal to the length of the shielding pipe (100mm or 250mm).

3、 Installation selection:
1. Antenna size: The larger the antenna, the smaller the beam angle, and the weaker the interference echo.
2. Antenna adjustment: Adjust the antenna to a good measurement position
3. Waveguide tube: A waveguide tube is used to avoid interference with echoes
