It deals with cylindrical storage tanks equipped with upper and lower conical end caps; the distance from the radar flange to the bottom reflector of the tank is 5.6 M. How should the various parameters related to distance and height be set?
Tank height: It is recommended to measure from the lower surface of the radar flange to the lowest edge of the column; this measurement can be extended slightly downward depending on the installation location and conditions. Upper blind zone: from the radar flange to the end of the upper cone, plus 200; or set everything above the actual highest feeding position as a blind zone. Antenna type, tank type – use the actual settings. The filter line can be set to 800 first; it’s best to include a sketch showing the installation location and the distances between various points
You’d better create an operation tree for him:lol
Height: 5.6 m, blind zone: ≥0.4, range: ≤5.2 meters. Set it up as mentioned on the second floor.

Set the bottom of the tank as flat, and the tank height to 5.6 (it’s best to consider the distance from the flange to the lowest point of the cylindrical part as the tank height). The upper limit of the measurement range should be less than or equal to 5.6 minus the blind zone. The initial value for the filtering line can be set at 800; if 475 is available, it’s better to examine that value in detail before setting the filtering line
Setting the measurement this way will definitely result in inaccurate results! For a flat-bottomed tank, the tank height below the bottom semi-circular weld should also be deducted.

Of course, it would be best to set the total height from the flange to the end of the cylinder to the height of the tank, as you mentioned
If he has a need, I can also send him an operation guide
