Step Ten
The
Low Dielectric Medium
function has the following settings (
and should not be performed without first
consulting with the factory
):
When the dielectric constant of the media is ≤ 4, the amplitude of the direct
echo from the media may be low and difficult to detect. However, by
measuring the echo reflected from the bottom of the tank, the media level can
be measured. Two parameters must be input to complete the setup: 1)
Distance from the bottom of the sensor to the tank bottom (Empty Span) and;
2) Distance from the tank bottom to the media level (True Level).
Empty Span
- Distance from the bottom of
the sensor to the tank bottom.
True Level
- Distance from the tank bottom
to the media level.
DK
- Media dielectric constant (determined
by sensor).
Note: Once this feature has been activated, only a factory setting can undo
its activation. A factory reset will erase all active settings including Echo
Curves.
DAMPEN
This function sets the sampling rate for which the sensor updates the current
output. The value is entered in seconds.
Default is 6 seconds
.
Decreasing the value will make the output more responsive to level
changes.
Increasing the value will make the output less responsive to level changes.
OUTPUT MAPPING
This function sets the correlation between the measured value and the current
output. Selections are Linear or Non-Linear.
Default is Linear
.
Keep the setting on Linear.
Note: This setting should not be changed
without first consulting with the factory.
SCALED UNITS
This function sets the type of measurement (Height, Volume, Mass, Flow or
No-Units) and units of measurement (which vary based upon the type of
measurement) displayed and input during configuration.
Default is Height in
Units of feet (ft)
.
