Description
The Insulation Factor Dry (0 < Insulation <= 1.0)
indicates how well the tank shell is insulated from the
environmental temperature (AmbientTemp) outside the
tank for the dry portion (Vapour space).
The Insulation Factor Wet (0 < Insulation <= 1.0)
indicates how well the tank shell is insulated from the
environmental temperature (AmbientTemp) outside the
tank for the wet portion (Liquid space).
This correction is only applicable on fixed roof tanks
without stilling well and corrects for the changes in GRH
due to the lifting of the roof caused by the vapor pres-
sure under the roof of the tank.
Selection: Enable / Disable
GRH Pressure Factor:
This indicates level change per unit pressure.
Description
Movement Detection Trip Value.
Whenever MoveDir is calculated, the actual measured
level is compared with [ProductLevel] at the time of the
previous check, see MoveInterval.
If the difference exceeds the value of MoveTrip, thus
reducing the effect of ext
Interval Time for MoveDir Calculation.
MoveIterval (>= 0) is the interval time, in seconds, after
which the movement direction of [ProductLevel] must
be calculated again.
MoveInterval is checked each time that the tank is cal-
culated ([ProductLevel] is me
