5.3.3 Set reservoir geometry
The reservoir geometry settings are crucial for the auto tune
program and flow estimations. Please enter values as pre-
cisely as possible, failing to do so will result in inaccurate
measurements.
Navigate to menu “[3A31] Level 1” or press toggle button.
Start from the bottom level (level 1) and set a corresponding
area for each change of shape in the reservoir. It is possible to
use 5 levels and areas. Use as many as required, unused lev-
els/areas should be set to 0/Off.

Level 1 = 0 m
Area 1 = Radius is 0.6 m, area 1 is calculated:

Level 2 = 0.6 m,
Area 2 = Radius is 0.6 m, area 2 is calculated:

Level 3 = 0.5 m
Area 3 = Radius 0.9 m, area 3 is calculated:

Level 4 = 1.5 m
Area 4 = Radius 0.9 m, area 4 is calculated:

Example with rectangular reservoir:
Level= X m,
Area = A x B m
2
Level 1: 0 m
Area 1 : A= 1.2 m, B= 0.5m, area 1 is calculated:
1.2 x 0.5 = 0.6 m
2
Level 2 = 0.6 m,
Area 2 : A= 1.2 m, B= 0.5m, area 2 is calculated:
1.2 x 0.5 = 0.6 m

Level 3 = 0.5 m
Area 3 : A= 1.8 m, B= 0.5m, area 3 is calculated:
1.8 x 0.5 = 0.9 m
2
Level 4 = 1.5 m
Area 4 : A= 1.8 m, B= 0.5m, area 4 is calculated:
1.8 x 0.5 = 0.9 m
