GetComputedTimeSeries VS GetComputedHydraulicTimeSeries

Hello,
I hope someone would help me!
If I want to estimate the consumption of my pump, Should I use GetComputedHydraulicTimeSeries? Then sum the column corresponding at the pump in the section “Energy” present in the Structure?
I didn’t understand very well the differences between GetComputedTimeSeries and GetComputedHydraulicTimeSeries. Maybe should I sum only the values of the energies corresponding at the moments present in GetComputedTimeSeries(every exact hour)?

Thank you so much
