TherststepinndingGPMistosubtractleavingwaterpressurefromenteringwaterpressure.Thedifferencebetweenthetwo
isreferredtoas∆P.∆PcanbeconvertedtoGPMbylookingintheequipmentspecicatoncatalog.Caution ∆P ≠ GPM
Note: A conversion table must be used to nd GPM from (Delta) ∆P measurements.
