ADM003GVAE1005 347
MASS AVAILABLE - AVAILABLE MASS
This process variable is the Mass of product that can safely be issued from the tank. FuelsManager normally
calculates this by subtracting the Mass at the minimum working level from the current Mass. However, this value
can be measured by automatic tank gauging systems or manually entered by the operator
VOL STRAP - H20 - STRAP VOLUME MINUS WATER VOLUME
This process variable is the tank strapping volume minus the water volume. FuelsManager normally calculates
this by subtracting the current water volume from the current strapping volume. However, this value can be
measured by automatic tank gauging systems or manually entered by the operator
VOL STRAP - COR EXP - STRAP VOLUME MINUS CTSH
This process variable is the tank strapping volume minus the thermal expansion effect of the tank shell.
FuelsManager normally calculates this by subtracting the volumetric effect of the tank shell correction factor from
the current strapping volume. However, this value can be measured by automatic tank gauging systems or
manually entered by the operator
VOL NET - C&W - NET VOLUME MINIUS C&W CORRECTION
This process variable is the Net Std. volume minus the correction for sediment and water. FuelsManager
normally calculates this by subtracting the correction for sediment and water from the current Net Std. volume.
However, this value can be measured by automatic tank gauging systems or manually entered by the operator
TANK SHELL COR. FAC - TANK SHELL CORRECTION FACTOR
This process variable is the tank shell correction factor, used to correct gross volume for the effects of tank shell
thermal expansion. FuelsManager normally calculates this from product temperature, ambient temperature, shell
material, and type of tank shell, the variable can also be linked to automatic gauging systems or manually
entered if required
C&W COR. FAC - C&W CORRECTION FACTOR
This process variable is the correction for sediment and water, used to correct gross volume for the effects of
water and sediment in the bottom of the tank. FuelsManager normally calculates this from water level and solids
level variables, the variable can also be linked to automatic gauging systems or manually entered if required
BSW VOLUME - VOLUME FOR %BSW
This process variable is the volume base, sediment and water impurities in the tank. FuelsManager normally
calculates this from the %BSW value and the current gross volume. However, the value can also be measured
by automatic tank gauging systems or manually entered by the operator
TANK BOTTOM VOLUME - TOTAL BOTTOM VOLUME
This process variable is the combined water and solids volumes in the tank. FuelsManager normally calculates
this by adding the water volume to the solids volume values. However, the value can also be measured by
automatic tank gauging systems or manually entered by the operator
VAPOR TEMP. - VAPOR TEMPERATURE
This process variable is the temperature of the vapor space above the product in the tank. This variable is
usually measured by automatic tank gauging but can be manually entered by the operator. This data is normally
only applicable to tanks containing liquified hydrocarbons.
