Where: Gr=Gross volume loaded for the Regular component
Gbm-Ge=Gross volume loaded difference between Blend and Ethanol
Tr=Temperature for the Regular component
((Tbm * Gbm) – (Te * Ge)) / Gr=Back calculated average temperature for the Regular component
Dr=Density for the Regular component
Dr’=Density specified for the Regular component
((Dbm * Gbm) – (De * Ge)) / Gr=Back calculated average density for the Regular component
(see Preset Level Parameter Compute Blend Density)
Nr=Net volume loaded for the Regular component
Nbm-Ne=Net volume difference between the Blend Net Volume and Ethanol Net Volume
Mr=Mass loaded for the Regular component
Mbm-Me=Mass difference between the Blend Mass and Ethanol Mass

Regular meter (Meter Level) values are reported as:
Grm=M1
Trm=T1
Drm=D1 OR Dr
Nrm=Grm*VCFr(Trm,Drm)
Mrm=Nrm * Drm OR Mrm=Grm * D1
Where: Grm=Gross volume loaded for the Regular Meter
M1=Gross volume reported by meter M1 while flowing Regular
Trm=Temperature for the Regular Meter
T1= Volume weighted average temperature reported by probe T1 while flowing Regular
Drm=Density for the Regular Meter
