46 BM 70 M
Input the following parameters:
Tank height
6 m
Reference offset + 1 m
Tank bottom offset 0
The possible measuring range is:
Distance = (1 m + block distance) to 7 m.
Example 2
Reference point for level measurement
differs from the programmed tank bottom
position (in the example, 2 m below the
tank bottom).
Let the tank height be H = 6 m.
Input the following parameters:
Tank height
6 m
Tank bottom offset + 2 m
Reference offset 0
The possible measuring range is:
Level = 2 m to (8 m - block distance)
Example 3
Only a specific part of the level in a very
tall tank is to be measured (in the example,
levels 50m ... 60m).
Input the following parameters:
Tank height
10 m
Tank bottom offset + 50 m
Reference offset 0
The possible measuring range is:
Level = 50 m to (60 m - block distance).
H = 6m
