Description
This indicates whether Water volume is calculated
based on Tank TCT or separate Water TCT.
Selection: None | Main TCT | Separate Water TCT
Note:
Often the water content is much smaller than the actual
heel volume of the tank. In these cases the use of the
regular TCT for assessing the free water volume is use-
less.
Often also the (free) water level is measured in a sepa-
rate 'water sump' as innage. Consequently a zero read-
ing is not equivalent with the zero volume of the TCT
(which is by definition equal to the heel volume).
Hence the need to be able to define a separate (Free)
water TCT, which is only used for calculating the water
volume which can then be subtracted from the TOV.
The file name and path of the water TCT file selected by
the user.
Water Volume under Range.
Whenever the Free Water Level drops below the mini-
mum Value, the Water Volume will no longer be calcu-
lated. The "WaterVolumeUnderRange" will be used
instead.
This entity is configured by the service tool.
Status "reduced accuracy" of Water Volume is not
inherited by derived data.
Status "manual" of (manually entered) ProductTC
(Alpha), is not inherited by derived data.
Status "manual" of (manually entered) [CTL], is not
inherited by derived data.
Status "not calibrated" of Water Volume is not inherited
by derived data if water is measured automatically
Status "stored" of the following entities is not inherited
by derived data:
•
WaterVol (WaterLevel was measured via a Water
Dip: 811/854/954 gauge)
•
ProductDRef ([DObs] was measured via a Density
Dip: 854/954 gauge)
