material is computed based on the tank volume setup
and the level measurement. The volume of the tank
when full is required to compute the ullage (empty
volume), the % full and the % empty values.

If “mass” is selected, the following menu items are displayed.
Mass
units: Kgram
NEXT↓↓ CHANGE→→
Select the units for the mass measurement. Available
units are: gram, kgram, pound, metric ton, short ton,
long ton, and oz.
material density
0.000 Kgram/cu ft
NEXT↓↓
Enter the material density value. The density value
(mass / volume) must be specified in the same units
selected for mass and volume. Density values < 0.1
are displayed in scientific notation and the units are
not displayed due to display space constraints.
If “rate” is selected the following menu items are displayed.
rate readout will be
rate of:
Distance/time
NEXT↓↓ CHANGE→→
Select a (previously setup) measurement (distance in
this example) for which to compute the rate of
change. Measurement number for rate should be
greater than the number of the base measurement.

Rate will not be computed until the change in the
measurement exceeds the value entered here. Once
rate has been computed, it is recomputed when the
change threshold is exceeded or when the expected
time for the change threshold to be exceeded has
elapsed.
rate smoothing

{0.01 to 1.0} NEXT↓↓
Smoothing factor for rate measurement. A value of
1.0 corresponds to no smoothing (current estimate is
displayed), a value of 0.01 corresponds to the most
smoothing (longest effective averaging time).

Select the reference time interval for the rate
measurement. Choices are: s (seconds), m (minutes),
h (hours), d (days), w (weeks), M(months), and
y (years).
The next menu item is displayed only if “Service Only Items” are enabled.
