H: Parameters
2.6.5. Dimension L (default 0.0)
Length of the cylindrical section of a horizontal parabolic end tank, in level units.
See page 85 for an illustration.
1. Go to Input > Sensor Calibration > Unit (level) and select desired
level units.
2. Key in the height of the vessel bottom in level units.
2.7. Detailed Setup
2.7.1. Failsafe
2.7.1.1. LOE (Loss of Echo) Timer (default 10)
Amount of time, in minutes, that a Loss of Echo must persist, before the
device goes into Failsafe mode. See page 36 for more details.
2.7.2. Volume
When the vessel shape is too complex for any of the preconfigured shapes, you
can define the shape as a series of segments. First assign a value to each level
breakpoint, then assign a corresponding value to each volume breakpoint.
(Volume values can be percent or volumetric; level values can be percent or
linear.)
Enter up to 32 level breakpoints, where the corresponding volume is known. The
values corresponding to 100% and 0% levels must be entered. The breakpoints
can be ordered from top to bottom, or the reverse. Breakpoints are normalized to 0.
