Notes:
7 _{Gas correction factors are referenced to nitrogen (N2) as calibration gas type. Approximate gas correction factors are provided}
as guidelines only. Individual gas types may perform differently at temperature extremes and varying flow rates.
8 _{When sensing Hydrogen (H2) or Helium (He) it may be necessary to power the mass flow sensor using increased supply voltage:}
Hydrogen typ. 12 V, Helium typ. 15 V
9 _{Hydrogen (H2) flow measurement requires the use of a special sensor. These devices provide normal operation when sensing}
hydrogen flow and are designated with an "H" at the end of the order number.
