API BIO
This API BIO tables are used for Methode3 from the PTB Community. Select API Table
Name PTB-BIO table combined with API BIO to choose the wanted product.
Formula: V(T) = V0 *{1 + [A1 *(T – T0) + A2 *(T – T0)2 + A3 *(T – T0)3]}
V0 = Volume @ base temperature
V(T) = Volume @ observed temperature
T0 = Base Temperature (15° C)
T = Observed Temperature
A1, A2, A3 = Biofuel coefficients
API Gravity
For API tables that require the entry of an API Gravity value, enter that value here. The
value should be the API Gravity of the component at 60  F. The units are degrees API.
Relative Density
For API tables that require the entry of a relative density, enter that value here. The
value should be the relative density of the component at 60  F. Note that Relative
Density is unit less.
Default Density
For API tables that require the entry of density, enter that value here. The value should
be the density of the component at 15  C. The units are kg/m3.
When this value is non-zero, this value will be reported as the component level density
and may be used as the meter level density if a density is not defined at the meter level.
If this value is zero, the meter level density will be used as the component level density.
If this is the main component on a side stream blend, a density will be back calculated
from the meter level density and the side stream meter or component density.
Expansion Coef.
For API tables that require the entry the coefficient of expansion, enter that value here.
The value should be the coefficient of expansion of the component @ 60F or 15 C,
depending on the table.
Hydrometer Used
In cases where a Hydrometer is used to determine API Gravity or Density, enable this
Parameter.
Commodity Type
Only used for API X tables: No type, Crude, Refined and Lubric
Expansion Coef. UOM
Only used for API X tables: C or F
Density UOM
Only used for API X tables: kg/m³ ,API Gravity and Relative Density
Pressure UOM
Only used for API X tables: BAR, PSIG and kPA
Reference
Temperature
This is used for the API X tables, but also for the ethanol tables.( TEC B40 , TEC B100,
TEC E40, TEC E100)
Alcohol Percentage
(Excluding SCS)
This percentage value is only used for the Brazilian alcohol table. This value is needed
to determine the VCF.
API Alarm Time
This parameter is use for unloading Bays when the density, gravity or relative density
device gives an invalid value, because of Air in the line. By increase this parameter in
seconds it is possible to still offload without going into alarm. Last known density will be
used for calculation.
Compressibility Factor
This parameter will overwrite the Compressibility Factor (Fp) which is used to calculate
the CPL. It is required when using a C API table and when CPL is required. In all other
cases this value is optional. If MultiLoad has a known density this value should be set to
zero. The entered factor XXXXX equals in the formula 0.0000XXXXX per pressure unit.
Formula: cpl = 1/(1 - (Fp * pressure))
