process_flow_from_customer_scfm_<variant>
It the same as flow_from_customer_scfm_<variant>
but computed only if there is ongoing tower activity
for detail check flow_from_customer_scfm
TK700:
process_flow_from_customer_scfm_tk700 = process_flow_from_customer_scfm_ft202_corrected +
v(tk_700_scf, +10m) - v(tk_700_scf, -20m) +
v(hxr_600_ar_scf, +10m) - v(hxr_600_ar_scf, -20m) if !XV1123OUT and !ctx(XV1123OUT, 3m)
else process_flow_from_customer_scfm_ft202_corrected
If XV-1123 is open AND XV-703 is open, then it means virgin gas is coming into the TK-700, which means we’d need to adjust the TK-700 net change. However, this circumstance is expected to be very rare and only possible via manual intervention, so it is fine to omit this condition for now.
TK1101:
process_flow_from_customer_scfm_tk1101 = process_flow_from_customer_scfm_ft202_corrected +
v(tk1101_scf, -1m) - tk1101_scf if !XV1123OUT and !ctx(XV1123OUT, 3m)
else process_flow_from_customer_scfm_ft202_corrected
BELLY
process_flow_from_customer_scfm_belly = process_flow_from_customer_scfm_ft202_corrected - belly_flow_heat_scfm
